react navigation How to close the DrawerNavigator nested StackNavigator? - react-native

I want to close the Drawer on screen: ExportClues, but it is not working.
This is my code.
const Drawer = DrawerNavigator( {
Navigators: {
screen: Navigators
},
{
initialRouteName: 'Navigators',
drawerWidth: Metrics.screenWidth - 95,
drawerPosition: 'right',
contentComponent: MenuNavigator
}
})
const Navigators = StackNavigator({
...screen
})
const MenuNavigator = StackNavigator({
ExportClues: {
screen: ExportClues,
},
...other screen
})
It is ExportClues Component:
export default class index extends Component {
render() {
return(
<View
style={{flex: 1, backgroundColor: '#ffffff'}}
>
<TouchableOpacity
onPress={()=>{
this.props.navigation.navigate('DrawerClose');
// It is not work
}}
>
<TouchableOpacity/>
</View>
)
}
}
Sorry, My english is very poor.
How to get MenuNavigator Parent Navigator as DrawerNavigator?

Looking at the link you provided, you are trying to include the Drawer component incorrectly:
You write
import Drawer from './drawer'
and try to use component
but your drawer.js file is exporting "CustomerManagerDrawerNavigator"
export default CustomerManagerDrawerNavigator;
which means your code should be
import CustomerManagerDrawerNagivator from './drawer'
and your component should be called as
in the render() function.
If you want to use DrawerNavigator you need to to change your
const MenuNavigator = StackNavigator({
to
const MenuNavigator = DrawerNavigator({
to close the drawer while in ExportClues, you would call
this.props.navigation.navigate('DrawerClose'); // close drawer
which I see you have but you aren't passing any navigationOptions to in your Navigator configuration, so you don't have access to the navigate function. You need something like the code below:
navigationOptions: ({navigation}) => ({
.../*Your navigation options here */
}),
to pass navigation as a prop to your open Drawer
I would review the React-Navigation homepage for DrawerNavigator located at https://reactnavigation.org/docs/navigators/drawer for more details or if possible post a link to a working repository

How to navigate to another screen from a function component?

I have a tabBarNavigation and i have a Home component. In the Home component i want to be able to navigate between two different screens. I have a component called ReadButton which when pressed should take me to another screen called 'BookScreen'. Now i have written so my HomeStack component have two screens 'HomeScreen' and 'BookScreen'. My problem is i cant make the 'ReadButton' to navigate to 'BookScreen' when pressed. It says ''Undefined is not an object(evaluating props.navigation.navigate).
...//This is in the main class provided by react
const HomeStack = createStackNavigator(
{
Home: HomeScreen,
Book: BookScreen,
},
config
);
const tabNavigator = createBottomTabNavigator({
HomeStack,
LinksStack,
SettingsStack,
});
tabNavigator.path = '';
export default tabNavigator;
...
//Below is the ReadButton class in a seperate file
import {withNavigation} from 'react-navigation'
const ReadButton = (props) => {
const [ReadPressed, setReadPressed] = useState(true)
const {navigate} = props.navigation.navigate
if(ReadPressed){
return(
<View>
<TouchableOpacity style={styles.buttonstyle} onPress={navigate("Home")}>
<Text style={styles.textstyle}> READ </Text>
</TouchableOpacity>
</View>
)
}
else {
return(
props.book
)
}
}
// Another class where i have my <ReadButton>
function BookCover(){
<TouchableOpacity style={styles.bottomFlexItemWhenClicked} onPress= .
{() => setBookCoverState(true)}>
<Text style={styles.BackgroundText}>{props.text}</Text>
<ReadButton book={props.book} navigation={props.navigation}>
</ReadButton>
</TouchableOpacity>)}
}
export default withNavigation(ReadButton);
Now i have tried putting 'Book: BookScreen' over 'Home: HomeScreen' and then the screen actually shows but i cant navigate between them. What am i missing?
Maybe you can try hooks?
install hooks: yarn add react-navigation-hooks#alpha
and then use it in your function component:
import { useNavigation } from 'react-navigation-hooks'
export default function Screen1 () {
const { navigate } = useNavigation()
return (
<Button
title='Try'
onPress={() => { navigate('Screen2') }}
/>
)
}
Please note that components inside the HomeScreen or BookScreen won't receive the navigation prop.
1.Either you send them manually like this
<ReadButton navigation={this.props.navigation}/>
or
2.Use the built in withNavigation of react-navigation like this
import {withNavigation} from 'react-navigation'
const ReadButton=(props)=>{}//Now you can access navigation prop here
export default withNavigation(ReadButton)
Second method will come to handy when your component is deeply nested and you want to access the navigation prop without manually passing the props.

React-Navigation: Navigation onPress doesn't work

I am a bit confused about this navigation system. I have root which I contain navigations in it. And I have two different screens. No problem till here. I put initialRoute and displaying SignInScreen. Also put a button for Sign Up screen but that button isn't working.
Root.js
const ScreenNavigator = createStackNavigator({
SignIn: SignInScreen,
SignUp: SignUpScreen,
},
{initialRouteName: 'SignIn' }
);
const ScreenContainer = createAppContainer(ScreenNavigator);
export default class Root extends Component{
render(){
return(
<ScreenContainer style={styles.container} />
);
}
}
and SignInScreen:
import SignUpScreen from '../screens/Signup';
export default class SignInScreen extends Component{
constructor(props){
super(props);
}
render(){
return(
<View style={styles.container}>
<Text>Sign in Screen </Text>
<Button
title={'Sign up'}
onPress={() => this.props.navigation.navigate('SignUpScreen')}
/>
</View>
);
}
}
is it something that I am missing here? Thank you for help.
There is nothing wrong in the code, you just miss spell the route.
There is no route name SignUpScreen, correct route name is SignUp and SignIn
confusion is due to change in api of react navigation
before we define a route like
Login: {
screen: LoginScreen
}
so login is a route name and screen is just a component we need to render
but after 2^ version, it changed to
{SignIn: SignInScreen}
so now name is SignIn and component is SignInScreen
even if you want a route name as component just do
const ScreenNavigator = createStackNavigator({
SignInScreen,
SignUpScreen,
},
now you route name is SignInScreen and SignUpScreen
hope this information is enough
Issue in route name.
onPress = {() => this.props.navigation.navigate('SignUp')}
Try to keep the route names in constant file. It may make things easier to handle.
const routes = {
route1: 'route1',
route2: 'route2',
};
const ScreenNavigator = createStackNavigator({
[routes.route1]: Screen1,
[routes.route2]: Screen2,
},
{initialRouteName: routes.route1 }
);

React native set state from drawer navigator to other component

On first screen I have a component having some listing of products say ProductListing.js. And on drawer navigator I have some check boxes. I want to set state of ProductListing.js when I am clicking on any check box of navigator.
App.js
import React, {Component} from 'react';
import Router from './src/config/routes';
export default class App extends React.Component {
render () {
return (
<Router/>
);
}
}
Router.js
export default DrawerNavigator({
Dashboard: {screen: Dashboard},
CreateLogin: {screen: CreateLogin},
Test: {screen: Test}
}, {
contentComponent: SideMenu,
drawerWidth: 300,
drawerPosition: 'right'
});
SideMenu.js
render () {
const { data, searchTerm, searchAttribute, ignoreCase, checked } = this.state;
return (
<View style={styles.container}>
<ScrollView>
<View>
<TextInput
style={styles.search} placeholder={"Search"}
onChangeText={searchTerm => this.setState({ searchTerm })} />
<SearchableFlatList
data={data} searchTerm={searchTerm}
searchAttribute={searchAttribute} ignoreCase={ignoreCase}
renderItem={({ item, index }) => <CheckBox
title={item.name +' ('+ item.count+')'}
onPress={() => this.handleChange(item.id)}
checked={checked[item.id]} />
}
keyExtractor={({id}, index) => index.toString()} />
</View>
</ScrollView>
<View style={styles.footerContainer}>
<Text>Apply filter by choosing filter values</Text>
</View>
</View>
);
}
}
ProductListing.js
constructor(props){
super(props);
this.state ={ isLoading: true,isloadmore: false, page :1,dataSource: [],countryFilter:0, gradesFilter:'',country:'',totalRecord:0};
}
render(){
const { navigation } = this.props;
return(
<View style={{flexDirection:'column',paddingRight:8}}>
<Button
title='Filter'
buttonStyle={{backgroundColor:'#000000',borderRadius:2}}
onPress={() => navigation.dispatch(DrawerActions.openDrawer())}
/>
</View>
);
}
Now on click of handleChange in SideMenu.js I want to update state of gradesFilter in ProductListing.js where I am updating my product listing.
You can easily achieve this with a portal! Take a look here.
You can pass the parameters from drawer to the Product screen via navigation params.
For this, you need to stackNavigator inside your DrawerNavigator like:
Router:
const MyStack = StackNavigator({
Dashboard: {screen: Dashboard},
CreateLogin: {screen: CreateLogin},
Test: {screen: Test}
});
const MyDrawer = DrawerNavigator({
Main: { screen: MyStack }
},
{
contentComponent: SideMenu,
drawerWidth: 300,
drawerPosition: 'right'
});
export const Router = StackNavigator({
Login: {screen: Login},
Drawer: {
screen: MyDrawer,
navigationOptions: { header: null } } //prevent double header
});
Now you can navigate and pass parameter from login or Dashboard or anyother screen via Drawer like
_login() {
this.props.navigation.navigate('Drawer', { parameter: userName });
}
And to use this parameter you need to access:
const { parameter } = this.props.navigation.state.params;
which you can further use to set state like
this.setState({
productSelection: parameter)};
Another approach can be via, listener/ Callback handler.

NativeBase Drawer Props

Is it possible to pass props at Sidebar of Drawer (SideBar i'ts my custom component). In this example test props isn't shown in SideBar
render () {
const sideBar = <SideBar onRest={this.changeToRest} test="12" />
return (
<Drawer ref={ref => (this.drawer = ref)} content={sideBar}>
....
Yes it's possible to pass the props to the sidebar custom component
<SideBar onRest={this.changeToRest} test="12" />
1.Here you can pass the test="12" as a props
2.You can get the props at the sidebar component {this.props.test} like that
You can add the Sidebar component to the Drawer DrawerNavigator like below
const DrawerNav = DrawerNavigator({
MainScreen: {
screen: TabNav
},
ProfileScreen: {
screen: ProfileNav
},
NotificationScreen : {
screen: NotificationNav
},
RewardScreen: {
screen : RewardNav
}
},{
drawerPosition: 'left',
initialRouteName: 'MainScreen',
contentComponent: props => <SideBarNav {...props} test="12"/>
});

React Navigation StackNavigator not appearing when used inside another view

I'm attempting to use a React Navigation StackNavigator for a process that includes a static component at the top of the page and varying components at the bottom. The code I'm using is:
const Navigator = StackNavigator ({
splash: Splash,
prompt: Prompt,
pinCheck: PinCheck
}, {
initialRouteName: 'splash'
});
export default class Login extends React.Component
{
constructor (props)
{
super (props);
// code to set up animation state
}
componentDidMount()
{
// code to set up animation
}
finish_ (state)
{
this.props.navigation.navigate ('main', state);
}
render()
{
const screen = Dimensions.get('screen');
return (
<KeyboardAvoidingView style={Global.styles.verticalFill} ref={this.saveContainerRef}>
<ScrollView style={{flex: 1}} contentContainerStyle={{justifyContent: 'space-between'}}>
<Animated.View style={{opacity:this.state.fade1,alignItems:'center'}} >
<Image
style={{width:screen.width * 0.6,height: screen.height*0.55}}
source={imgLogo}
resizeMode='contain'
/>
<Navigator />
</Animated.View>
</ScrollView>
</KeyboardAvoidingView>
);
}
}
When I run this, however, my initial route component is not shown. It works correctly if I swap <Navigator/> to <Splash/> however, so the component itself definitely works in this context.
Any ideas what's wrong?
There is a problem in your navigation setup.
All the routes in the StackNavigator must declare a screen
as mentioned in the docs
const Navigator = StackNavigator ({
splash: {
screen: splash
},
prompt: {
screen: prompt
},
pinCheck: {
screen: pinCheck
}
}, {
initialRouteName: 'splash'
})
