React native elements header background image - react-native

I made a header using react native elements, and I want to add background image into it. Is there anyway to do it?
I am using react-native-elements: "^0.19.1"
Here is my header code
render() {
return (
<View style={{ paddingTop: Constants.statusBarHeight, backgroundColor: color.light_grey }}>
<Header
leftComponent={this.props.left ? this.props.left : <IconWrapper name='menu' color='black' size={28} style={styles.icon} onPress={() => Actions.drawerOpen()} />}
centerComponent={<Text style={styles.headerText}>{this.props.title}</Text>}
rightComponent={this.props.right ? this.props.right : <IconWrapper name='handbag' type='simple-line-icon' color='black' size={28} style={styles.icon} onPress={() => Actions.BagContents()} />}
outerContainerStyles={[styles.headerOuterContainer, { height: 0.08 * windowHeight() }]}
/>
</View>
)
}
}

You can always create your own <Header/> component, probably will take you more time but you will be able to understand it and edit it as you like. I created a simple Header component to show you how you can accomplish adding a background image to your header. See the snack #abranhe/stackoverflow-56729412
Header.js
import React, { Component } from 'react';
import { View, TouchableOpacity, StyleSheet, Dimensions, ImageBackground } from 'react-native';
export default class Header extends Component {
renderContent() {
return (
<View style={styles.content}>
<View style={styles.left}>{this.props.left}</View>
<View style={styles.center}>{this.props.center}</View>
<View style={styles.right}>{this.props.right}</View>
</View>
);
}
renderHeaderWithImage() {
return (
<ImageBackground style={styles.container} source={this.props.imageSource}>
{this.renderContent()}
</ImageBackground>
);
}
renderHeaderWithoutImage() {
return (
<View style={[{ backgroundColor: '#f8f8f8' }, styles.container]}>
{this.renderContent()}
</View>
);
}
render() {
return this.props.image
? this.renderHeaderWithImage()
: this.renderHeaderWithoutImage();
}
}
const styles = StyleSheet.create({
container: {
top: 0,
position: 'absolute',
width: Dimensions.get('window').width,
backgroundColor: '#f8f8f8',
borderBottom: 1,
borderColor: '#f8f8f8',
shadowColor: '#000',
shadowOffset: { width: 0, height: 2 },
shadowOpacity: 0.5,
},
content: {
width: '100%',
flexDirection: 'row',
justifyContent: 'space-between',
alignItems: 'center',
marginTop: Dimensions.get('window').height * 0.03,
height: Dimensions.get('window').height * 0.045,
},
left: {
marginHorizontal: 5,
},
center: {
marginHorizontal: 5,
},
right: {
marginHorizontal: 5,
},
});
and then on when you want to use the Header component you can set the image prop to true, eg:
import React from 'react';
import { Text, View, StyleSheet } from 'react-native';
import { Ionicons } from '#expo/vector-icons';
import Header from './components/Header';
export default () => {
return (
<View>
<Header
image
imageSource={{ uri: 'https://yourimage.png' }}
left={<Ionicons name="md-arrow-round-back" size={25} />}
center={<Text>Projects</Text>}
right={<Ionicons name="ios-camera" size={25} />}
/>
</View>
);
};
and then if you set the image prop to false you will remove the image from the background.
<Header
image={false}
imageSource={{ uri: 'https://yourimage.png' }}
left={<Ionicons name="md-arrow-round-back" size={25} />}
center={<Text>Projects</Text>}
right={<Ionicons name="ios-camera" size={25} />}
/>

There is ReactNative's component ImageBackground you can use it.
like this,
<ImageBackground source={...} style={{width: '100%', height: '100%'}}>
<Header
leftComponent={this.props.left ? this.props.left : <IconWrapper name='menu' color='black' size={28} style={styles.icon} onPress={() => Actions.drawerOpen()} />}
centerComponent={<Text style={styles.headerText}>{this.props.title}</Text>}
rightComponent={this.props.right ? this.props.right : <IconWrapper name='handbag' type='simple-line-icon' color='black' size={28} style={styles.icon} onPress={() => Actions.BagContents()} />}
outerContainerStyles={[styles.headerOuterContainer, { height: 0.08 * windowHeight() }]}
/>
</ImageBackground>
You can always style it your way.

assuming you are using react-navigation
You need to add a custon header component in navigationOptions,
import { Header } from 'react-navigation';
static navigationOptions = ({ navigation }) => {
return {
header: (props) => <View >
<LinearGradient
style={{ height: '100%', width: '100%', position: 'absolute' }}
start={{ x: 0, y: 1 }} end={{ x: 1, y: 0 }} colors={['#1A9EAE', '#4EAE7C']}
/>
<Header {...props} style={{ backgroundColor: Colors.transparent }} />
</View>,
}
}

This works for me.
<Header
backgroundImage={require("../../assets/images/btn-header-background.png")}
centerComponent={{
text: i18n.t("stats.title"),
style: { fontFamily: "FunctionLH", fontSize: 30, color: "#fff" }
}}
containerStyle={{
backgroundColor: "transparent",
justifyContent: "space-around"
}}
statusBarProps={{ barStyle: "light-content" }}
/>

What's my mistake when using ternany operator with isTextInputFocused property in react-native?

I have a textInput. When i click on the textInput, i want "Search Icon" to be passive, but when i dont click on the textInput, i want "Search Icon" to be active,
Its strangely not doing what I want. As I look at my code, it looks correct, but i must have something wrong because it doesnt work as i wanted.(not giving an error tho)
App.js
import React from 'react';
import { StyleSheet, Text, View, TextInput, isTextInputFocused } from 'react-native';
import Search from "./src/icons/search.svg";
import {Loupe} from "./src/icons/loupe.png";
const App = () => {
return (
<View style={styles.container}>
<View style={styles.firstPart}>
<Text style={styles.date}>Saturday, Feb 21</Text>
<View style={styles.package}>
<Text style={styles.packageText}>Your Package</Text>
<View style={styles.plusIcon}>
<Text style={styles.textPlus}>+</Text>
</View>
</View>
{isTextInputFocused ? (<Search height={25} width={20} fill={"#00FF00"} style={{ position: "absolute", top: 90, left: 30, zIndex: 0 }} />):
(<Search height={25} width={20} fill={"#A9A9A9"} style={{ position: "absolute", top: 90, left: 25, zIndex: 20 }}/>)}
<TextInput style={styles.input} placeholder="Search" placeholderTextColor="gray"></TextInput>
</View>
{/* { !isTextInputFocused && (<View>
<Search height={30} width={30} fill={"#00FF00"} />
</View>)} */}
</View>
);
};
const styles = StyleSheet.create({
container:{
margin:10,
},
firstPart:{
backgroundColor: "mediumblue",
borderTopRightRadius:40,
borderTopLeftRadius:40,
padding:20,
},
date:{
fontSize:15,
color:"white",
},
package:{
flexDirection: "row",
justifyContent: "space-between",
},
packageText: {
fontSize:25,
color:"white",
flexDirection: "column",
},
plusIcon: {
height:25,
width:25,
borderRadius:25,
backgroundColor:"blue",
marginTop:5,
},
textPlus: {
fontSize:25,
fontWeight:"bold",
color:"white",
marginLeft:5,
},
input: {
height:40,
borderWidth:.5,
borderRadius:10,
marginVertical:10,
backgroundColor:"darkslateblue",
padding:5,
}
});
export default App;
You can use the TextInput component's onFocus, onBlur props to focus information on an input. Sample code is available below.
const [text, setText] = useState("")
const [inputFocus, setFocus] = useState(false)
return (
<View style={styles.container}>
<Text>
{inputFocus ? "Focused" : "Not Focused"}
</Text>
<TextInput
value={text}
onChangeText={setText}
onFocus={() => setFocus(true)}
onBlur={() => setFocus(false)}
style={{
width: "100%",
height: 44,
backgroundColor: "gray"
}}
/>
</View>
)

KeyboardAvoidingView doesn't work properly on my app

I searched a lot about this issue and I don't know what to do now so I decided to ask here and any help would be appreciated. in my register screen I have some input that user must fill and for the last one I need to avoid keyboard overlay. so I used KeyboardAvoidingView component to solve this but as you can see in the screenshot the device keyboard still overlay my input (birth date).
here is my code for this screen :
import React, { useState } from 'react';
import { View, Text, KeyboardAvoidingView, Image, Dimensions, PixelRatio, StyleSheet } from 'react-native';
import { widthPercentageToDP as wp, heightPercentageToDP as hp } from 'react-native-responsive-screen';
import { COLORS } from '../Constants/COLORS';
import PrimaryButton from '../Components/PrimaryButton';
import PrimaryInput from '../Components/PrimaryInput';
import CheckBox from '../Components/CheckBox';
const Register = (props) => {
const [lisenceTerm, setLisenceTerm] = useState(true);
const [privacyPolicy, setPrivacyPolicy] = useState(true);
return (
<View style={styles.screen}>
<View style={styles.imageContainer}>
<Image style={styles.image} source={require('../assets/Img/office_5.jpg')} />
</View>
<View style={styles.loginContainer}>
<View style={styles.headerContainer}>
<Text style={styles.headerText}>Join us</Text>
</View>
<KeyboardAvoidingView style={styles.inputContainer}>
<PrimaryInput placeholder='Name Surname' />
<PrimaryInput placeholder='Your Email' />
<PrimaryInput placeholder='Phone Number (05***)' />
<PrimaryInput placeholder='Birth Date' />
</KeyboardAvoidingView>
<View style={styles.checkBoxContainer}>
<CheckBox text='Kvkk sözleşmesini okudum, kabul ediyorum' active={lisenceTerm} onPress={() => setLisenceTerm(!lisenceTerm)} />
<CheckBox text='Kullanıcı sözleşmesini okudum, kabul ediyorum' active={privacyPolicy} onPress={() => setPrivacyPolicy(!privacyPolicy)} />
</View>
<View style={styles.buttonsContainer}>
<PrimaryButton
buttonStyle={styles.button}
textStyle={styles.buttonText}
title='Register' />
</View>
</View>
</View>
)
}
const styles = StyleSheet.create({
screen: {
flex: 1,
},
imageContainer: {
width: '100%',
height: '34%'
},
image: {
width: '100%',
height: '100%'
},
loginContainer: {
backgroundColor: 'white',
width: '100%',
height: '71%',
position: 'absolute',
zIndex: 1,
bottom: 0,
borderTopLeftRadius: 40,
borderTopRightRadius: 40,
alignItems: 'center'
},
buttonsContainer: {
width: '100%',
justifyContent: 'center',
alignItems: 'center'
},
button: {
justifyContent: 'center',
alignItems: 'center',
width: '75%',
paddingVertical: '3%',
marginTop: hp(1.2),
borderRadius: hp(3.5),
backgroundColor: COLORS.royalBlue
},
buttonText: {
fontSize: hp(3.2),
fontFamily: 'BalooPaaji2ExtraBold',
color: 'white'
},
arrow: {
right: 20
},
inputContainer: {
width: '100%',
justifyContent: 'center',
alignItems: 'center',
marginBottom: hp(1),
},
headerContainer: {
marginTop: hp(3),
marginBottom: hp(2),
width: '75%',
},
headerText: {
fontSize: hp(3.5),
fontFamily: 'BalooPaaji2Bold',
color: COLORS.royalBlue
},
checkBoxContainer: {
width: '70%',
justifyContent: 'flex-start',
marginBottom: hp(1)
}
})
export default Register;
and here below is the result. btw I used behavior and keyboardVerticalOffset props to control the way this component behave but still same problem.
Your KeyboardAvoidingView component must be on top of render tree
In order to scroll onto your Join us view, you must set a ScrollView in your KeyboardAvoidingView and those component must be on top of renderer.
Try this (based on my iOS / android setup) :
import { KeyboardAvoidingView, ScrollView } from 'react-native';
const Register = (props) => {
const [lisenceTerm, setLisenceTerm] = useState(true);
const [privacyPolicy, setPrivacyPolicy] = useState(true);
return (
<KeyboardAvoidingView
style={{ flex: 1 }}
behavior={(Platform.OS === 'ios') ? 'padding' : null}
enabled
keyboardVerticalOffset={Platform.select({ ios: 80, android: 500 })}>
<ScrollView>
<View style={styles.screen}>
<View style={styles.imageContainer}>
<Image style={styles.image} source={require('../assets/Img/office_5.jpg')} />
</View>
<View style={styles.loginContainer}>
<View style={styles.headerContainer}>
<Text style={styles.headerText}>Join us</Text>
</View>
<View style={styles.inputContainer}>
<PrimaryInput placeholder='Name Surname' />
<PrimaryInput placeholder='Your Email' />
<PrimaryInput placeholder='Phone Number (05***)' />
<PrimaryInput placeholder='Birth Date' />
</View>
<View style={styles.checkBoxContainer}>
<CheckBox text='Kvkk sözleşmesini okudum, kabul ediyorum' active={lisenceTerm} onPress={() => setLisenceTerm(!lisenceTerm)} />
<CheckBox text='Kullanıcı sözleşmesini okudum, kabul ediyorum' active={privacyPolicy} onPress={() => setPrivacyPolicy(!privacyPolicy)} />
</View>
<View style={styles.buttonsContainer}>
<PrimaryButton
buttonStyle={styles.button}
textStyle={styles.buttonText}
title='Register' />
</View>
</View>
</View>
</ScrollView>
</KeyboardAvoidingView>
)
}
you need to install react-native-keyboard-aware-scroll-view by
yarn add react-native-keyboard-aware-scroll-view
and you need to wrap KeyboardAwareScrollView instead of KeyboardAvoidingView
like
import {KeyboardAwareScrollView} from 'react-native-keyboard-aware-scroll-view';
<KeyboardAwareScrollView>
<View>
...
</View
</KeyboardAwareScrollView>
import { useHeaderHeight } from "#react-navigation/elements"
import {
Keyboard,
Platform,
TouchableWithoutFeedback,
View,
KeyboardAvoidingView
} from "react-native"
const Chat = () => {
// This is the crucial variable we will place it in
// KeyboardAvoidingView -> keyboardVerticalOffset
const headerHeight = useHeaderHeight()
return (
<TouchableWithoutFeedback onPress={Keyboard.dismiss}>
<KeyboardAvoidingView
style={{ position: "absolute", bottom: 0, left: 0, right: 0 }}
behavior={Platform.OS === "ios" ? "padding" : "height"}
// If you want the input not to stick exactly to the keyboard
// add a const here for example headerHeight + 20
keyboardVerticalOffset={headerHeight}
>
<View style={{ flex: 1, justifyContent: "flex-end" }}>
<InputWrapper>
<RawInput />
</InputWrapper>
</View>
</KeyboardAvoidingView>
</TouchableWithoutFeedback>
)
}

React Native animation transition opacity from 0 to 1 does not work

I am using expo with Android Virtual Device .I am trying to mimic this animation behavior from this example, https://codepen.io/borntofrappe/pen/qwqPwq,
Here is what it looks like right now:
I use flag array to represent which button is clicked, if the certain button is clicked, I will call handleSpeedBtn function to change its corresponding flag, when the flag is true, it will provide buttonTextLayer style to this button. Right now,I am having trouble displaying the buttonTextLayer style in animation style.It applies buttonTextLayer style to the button without any animation, besides, I do not have any errors when I run the code. Just change the opacity from 0 to 1 probably would not make my app looks like the example I found on codepen, but I just want to see the animation at least. Thanks for help!

React Native - Image bigger than parent

Like in tinder, i have a screen with 3 Image Pickers. When I pick an image from the gallery, I want it to persist inside the TouchableOpacity container. However, the image overlaps the container.
I have been been trying various things mentioned here but the image still overlaps like in the image below:
What is the problem?
/* eslint-disable react-native/no-inline-styles */
import React, { useState } from 'react'
import {
Text,
View,
Image,
Button,
TouchableOpacity,
StyleSheet,
Dimensions,
} from 'react-native'
import ImagePicker from 'react-native-image-crop-picker'
import { FontAwesomeIcon } from '#fortawesome/react-native-fontawesome'
import { faPlusCircle } from '#fortawesome/free-solid-svg-icons'
import Colors from '../../../constants/Colors'
const { width: WIDTH } = Dimensions.get('window')
const ProfileEdit = () => {
const [photo, setPhoto] = useState(null)
const handleChoosePhoto = () => {
ImagePicker.openPicker({
width: 300,
height: 400,
cropping: true,
}).then((image) => {
setPhoto({
uri: image.path,
width: image.width,
height: image.height,
mime: image.mime,
})
console.log(image)
})
}
return (
<View style={styles.main}>
<View style={styles.button_row}>
<View style={styles.buttonWrapper}>
<TouchableOpacity
onPress={() => handleChoosePhoto()}
style={styles.button}>
{photo ? (
<Image source={photo} style={styles.photo} />
) : (
<FontAwesomeIcon
icon={faPlusCircle}
color={Colors.defaultColor}
size={22}
style={styles.icon}
/>
)}
</TouchableOpacity>
</View>
<View style={styles.buttonWrapper}>
<TouchableOpacity
onPress={() => handleChoosePhoto()}
style={styles.button}>
<FontAwesomeIcon
icon={faPlusCircle}
color={Colors.defaultColor}
size={22}
style={styles.icon}
/>
</TouchableOpacity>
</View>
<View style={styles.buttonWrapper}>
<TouchableOpacity
onPress={() => handleChoosePhoto()}
style={styles.button}>
<FontAwesomeIcon
icon={faPlusCircle}

/>
</TouchableOpacity>
</View>
</View>
</View>
)
}
const styles = StyleSheet.create({
main: {
flex: 1,
},
icon: {},
button: {
height: `${100}%`,
backgroundColor: Colors.defaultWhite,
padding: 2,
alignItems: 'center',
justifyContent: 'center',
borderRadius: 3,
},
buttonWrapper: {
width: WIDTH / 3,

flexWrap: 'wrap',
flexDirection: 'row',
},
photo: {
width: WIDTH / 2,
height: WIDTH / 2,
// borderRadius: 3,
resizeMode: 'contain',
},
})
export default ProfileEdit
correct answer as described here
"However because images will try to set the width and height based on the actual size of the image, you need to override these style properties"
<Image
style={{
flex: 1,
alignSelf: 'stretch',
width: undefined,
height: undefined
}}
source={require('../../assets/images/onboarding-how-it-works.png')}
/>
Instead of calculating image width try this:
<TouchableOpacity
onPress={() => handleChoosePhoto()}
style={styles.button}>
{photo ? (
<View style={styles.photoContainer}>
<Image source={photo} style={styles.photo} />
</View>
) : (
<FontAwesomeIcon
icon={faPlusCircle}
color={Colors.defaultColor}
size={22}
style={styles.icon}
/>
)}
</TouchableOpacity>
const styles = StyleSheet.create({
photoContainer: {
// flex: 1
},
photo: {
height: WIDTH / 2,
width: '100%',
resizeMode: 'contain'
}
});
I prefer ImageBackground instead. Below is the code to achieve you the desired View:
<ImageBackground
imageStyle={styles.image}
style={styles.imageContainer}
source={{uri: this.state.imageUri}}>
<TouchableOpacity onPress={this._pickImage} style={{
height: WIDTH/2,
width: WIDTH/2,
justifyContent: "center",
alignItems: "center"}}>
<Entypo name="camera" color={Colors.GREY} size={35}/>
</TouchableOpacity>
</ImageBackground>

Customizing default navigation bar of react-native-router-flux

I am using react native router flux for navigation in my react native project. Router flux has a default navBar.
Is there a way to customize the navBar? like, changing colour of text and background.
I tried editing the file in node_modules/react-native-router-flux/src/navBar.js but it doesn't seem to work.
Please help me.
In your Router.js file where you create your scenes give a navBar property like for eg:
navBar={NavBar} and here my NavBar is actually a NavBar.js file in which I have customized the navigation bar
just have a look on my codes if that helps u
Router.js file:
import React from 'react';
import { Scene, Router } from 'react-native-router-flux';
import mainScreen from './components/mainScreen';
import challengeScreen from './components/challengeScreen';
import NavBar from './components/NavBar';
const RouterComponent = () => {
return (
<Router>
<Scene key="root">
<Scene key="homeScreen" component={mainScreen} hideNavBar={1} />
<Scene
key="screen2" component={challengeScreen} navTransparent={1}
navBar={NavBar}
/>
</Scene>
</Router>
);
};
export default RouterComponent;
NavBar.js file
import {
View, Image, StatusBar, TouchableWithoutFeedback
} from 'react-native';
import React, { Component } from 'react';
import { Actions, Router, Scene } from 'react-native-router-flux';
class NavBar extends Component {
render() {
return (
<View style={styles.backgroundStyle}>
<StatusBar />
<View style={{ flexDirection: 'row' }}>
<TouchableWithoutFeedback onPress={() => Actions.homeScreen()}>
<Image
source={require('./Images/back-arrow.png')}
style={styles.backarrowStyle} />
</TouchableWithoutFeedback>
<Image
source={require('./Images/help.png')}
style={styles.helpStyle} />
<Image
source={require('./Images/setting.png')}
style={styles.settingStyle} />
</View>
</View>
);
}
}
const styles = {
backgroundStyle: {
backgroundColor: 'transparent'
},
backarrowStyle: {
resizeMode: 'contain',
flexDirection: 'row',
width: 50,
height: 50,
left: 0,
justifyContent: 'flex-start'
},
helpStyle: {
resizeMode: 'contain',
width: 50,
height: 50,
left: 220,
justifyContent: 'flex-end',
position: 'relative'
},
settingStyle: {
resizeMode: 'contain',
width: 50,
height: 50,
justifyContent: 'flex-end',
position: 'relative',
left: 210
}
};
export default NavBar;
This helped me to customize navigation bar
hope that it helps you
You should add navigationBarStyle property for customizing navigation bar.You can review following code:
<Scene key="key1" icon={TabIcon} title="book-open">
<Scene key="key2" hideNavBar={false}
navigationBarStyle={{backgroundColor:'transparent',marginTop:8, borderBottomWidth:0}}
component={TestComponent}
title=""/>
</Scene>
Also this subject is mentioned in here.https://github.com/aksonov/react-native-router-flux/issues/160
There is a working example in the examples folder of the react-native-router-flux repository.
For instance, your custom navbar would be:
import { Image, Platform, StyleSheet, Text, TouchableOpacity, View } from 'react-native';
import React from 'react';
import { Actions } from 'react-native-router-flux';
const styles = StyleSheet.create({
container: {
height: Platform.OS === 'ios' ? 64 : 54,
flexDirection: 'row',
paddingTop: 20,
},
navBarItem: {
flex: 1,
justifyContent: 'center',
},
});
export default class CustomNavBar extends React.Component {
// constructor(props) {
// super(props)
// }
_renderLeft() {
if (Actions.currentScene === 'customNavBar1') {
return (
<TouchableOpacity onPress={() => console.log('Hamburger button pressed')} style={[styles.navBarItem, { paddingLeft: 10 }]}>
<Image
style={{ width: 30, height: 50 }}
resizeMode="contain"
source={{ uri: 'https://upload.wikimedia.org/wikipedia/commons/thumb/b/b2/Hamburger_icon.svg/1200px-Hamburger_icon.svg.png' }}
/>
</TouchableOpacity>
);
}
return (
<TouchableOpacity onPress={Actions.pop} style={[styles.navBarItem, { paddingLeft: 10 }]}>
<Image style={{ width: 30, height: 50 }} resizeMode="contain" source={{ uri: 'https://image.flaticon.com/icons/png/512/0/340.png' }} />
</TouchableOpacity>
);
}
_renderMiddle() {
return (
<View style={styles.navBarItem}>
<Text>{this.props.title}</Text>
</View>
);
}
_renderRight() {
return (
<View style={[styles.navBarItem, { flexDirection: 'row', justifyContent: 'flex-end' }]}>
<TouchableOpacity onPress={() => console.log('Share')} style={{ paddingRight: 10 }}>
<Image style={{ width: 30, height: 50 }} resizeMode="contain" source={{ uri: 'https://cdn3.iconfinder.com/data/icons/glypho-free/64/share-512.png' }} />
</TouchableOpacity>
<TouchableOpacity onPress={() => console.log('Search')} style={{ paddingRight: 10 }}>
<Image style={{ width: 30, height: 50 }} resizeMode="contain" source={{ uri: 'https://maxcdn.icons8.com/Share/icon/p1em/Very_Basic//search1600.png' }} />
</TouchableOpacity>
</View>
);
}
render() {
let dinamicStyle = {};
if (Actions.currentScene === 'customNavBar1') {
dinamicStyle = { backgroundColor: 'red' };
} else {
dinamicStyle = { backgroundColor: 'yellow' };
}
return (
<View style={[styles.container, dinamicStyle]}>
{this._renderLeft()}
{this._renderMiddle()}
{this._renderRight()}
</View>
);
}
}
It works perfectly for me. Just don't forget to set the navBar property of your Scene or Stack:
<Scene navBar={CustomNavBar} key='myKey' component={MyComponent} />
react-native-router-flux provide some api to do this, take a look at https://github.com/aksonov/react-native-router-flux/blob/master/docs/API_CONFIGURATION.md, maybe titleStyle and navigationBarStyle are what you need.
