I'm trying to set up a simple screen navigation bar using react-navigation. I've got the navigation working but can't make any icons appear on each tab.
I've tried using FontAwesome instead of IonicIcons but the same Box with an X through it appears in place of the desired icon.
import React, {Component} from 'react';
import {createBottomTabNavigator, createAppContainer} from 'react-navigation';
import Icon from 'react-native-vector-icons/Ionicons';
import HomeScreen from './screens/HomeScreen'
import SearchScreen from './screens/SearchScreen'
import ScanScreen from './screens/ScanScreen'
const TabNavigator = createBottomTabNavigator({
Home: {
screen: HomeScreen,
navigationOptions: {
tabBarIcon: () => (<Icon name="md-home" />)
}
},
Scan: {
screen: ScanScreen
},
Search: {
screen: SearchScreen
}
});
export default createAppContainer(TabNavigator);
You have to link it react-native-vector-icons, in your command prompt:
react-native link react-native-vector-icons

I'm getting the following error from my React Native Android app.
'The component for route Dashboard must be a React component. For example:
import MyScreen from './MyScreen'
...
Dashboard: MyScreen
You can also use a navigator:
import MyNavigator from './MyNavigator'
...
Dashboard: MyNavigator'
I believe the following code is the problem. I have no idea how to fix it though, and would really appreciate some help.
import { createStackNavigator, createAppContainer, createMaterialTopTabNavigator, createDrawerNavigator } from "react-navigation";
import Login from './Login';
import Dashboard from './Dashboard'
import PatientsScreen from './PatientsScreen'
const AppNavigator = createStackNavigator(
{
Home: { screen: Login },
Dashboard: { screen: DrawerNavigator, screen: DashboardTabNavigator }
},
{
headerMode: 'none'
}
);
const DashboardTabNavigator = createMaterialTopTabNavigator({
Patients: PatientsScreen
})
const DrawerNavigator = createDrawerNavigator (
{
Dashboard: { screen: Dashboard }
},{
initialRouteName: 'Dashboard'
}
)
export default createAppContainer(AppNavigator);
Here's a screenshot of what I am trying to achieve. The top left burger menu is a drawer navigator, and the tabs for patients, devices and recordings are what I'm working on now. I'm trying to use tab navigation logic with those. In the code I posted above, I am trying to set up a route to navigate to the PatientsScreen from the Dashboard.
Create your TopTabNavigator and DrawerNavigator before your StackNavigator.
You might check Dashboard: { screen: DrawerNavigator, screen: DashboardTabNavigator }, you're using the key twice, so only DashboardTabNavigator will be used.
From what you said and the screenshot you posted, I did it like this :
const DashboardTabNavigator = createMaterialTopTabNavigator({
Patients: PatientsScreen,
Recordings : RecordingsScreen,
Devices : DevicesScreen
})
const DrawerNavigator = createDrawerNavigator (
{
Dashboard: { screen: DashboardTabNavigator }
},{
initialRouteName: 'Dashboard'
}
)
const AppNavigator = createStackNavigator(
{
Home: { screen: Login },
Dashboard: {screen : DrawerNavigator }
},
{
headerMode: 'none'
}
);
Can you try below code
I have added mock RecordingScreen, DeviceScreen, change this as per your need
import { createStackNavigator, createAppContainer, createMaterialTopTabNavigator, createDrawerNavigator } from "react-navigation";
import React, {Component} from "react";
import {View, Text} from 'react-native';
import Login from './Login';
import Dashboard from './Dashboard'
import PatientsScreen from './PatientsScreen'
class RecordingsScreen extends Component {
render(){
return <Text>Recordings</Text>
}
}
class DevicesScreen extends Component {
render(){
return <Text>Devices</Text>
}
}
const DashboardTabNavigator = createMaterialTopTabNavigator({
Patients: PatientsScreen,
Recordings: RecordingsScreen,
Devices: DevicesScreen
});
const AppStack = createStackNavigator({
Dashboard: DashboardTabNavigator
});
const DrawerNavigator = createStackNavigator(
{
DrawerStack: AppStack
},
{
headerMode: "none"
}
);
const AppNavigator = createStackNavigator(
{
Home: Login,
Dashboard: DrawerNavigator
},
{
headerMode: 'none',
initialRouteName: 'Dashboard'
}
);
export default createAppContainer(AppNavigator);
I have two flows in my app in the main flow.. one is stack navigation and the other is drawer navigation. Stack navigation is working okay but drawer one is giving me this error -
Invariant Violation: The navigation prop is missing for this navigator. In react-navigation version 3 you must set up your app container directly. More info:
https://reactnavigation.org/docs/en/app-containers.html
App.js
import { createAppContainer,

I have also added <HomeDrawerNavigator/> component in my Homescreen.js.
I am new to react native and I am using React navigation 3.x. This is
my project structure.
Mydemo
----routes
--Home.route.js
----src
--pages
--AddUser.js
----App.js
Below I am sharing my route configurations:-
Home.route.js code:-
import { createStackNavigator, createAppContainer } from "react-navigation";
import AddUser from '../src/pages/AddUser';
const HomeStack = createStackNavigator({
Add:{
screen: AddUser
}
})
export default createAppContainer(HomeStack);
App.js Code:-
import {createSwitchNavigator} from 'react-navigation';
import HomeStack from './routes/Home.route';
export default createSwitchNavigator({
Home: HomeStack
}, {
initialRouteName: 'Home',
});
But I am getting this error:-
The navigation prop is missing for this navigator.
can anyone please guide me about what I am doing wrong ?
Thank you.
createAppContainer must be on top of your navigation config =>
Home.route.js
import { createStackNavigator } from "react-navigation";
import AddUser from '../src/pages/AddUser';
export default createStackNavigator({
Add: AddUser
})
App.js
import {createSwitchNavigator, createAppContainer} from 'react-navigation';
import HomeStack from './routes/Home.route';
const AppNavigator = createSwitchNavigator({
Home: HomeStack
}, {
initialRouteName: 'Home',
});
export default createAppContainer(AppNavigator);
I'm learning react native with configuring tabNavigator, DrawerNavigator, and StackNavigator into one without NativeBase or Expo with a single react-navigation library.
I achieved it but there comes an error when I perform some specific sequence in my application.
The application starts with Tab Screen. -> Change Tab -> Open Drawer -> Goto Stack -> open Drawer and then go to Tabs gives this error.
Here is my code :
App.js
import React from 'react';
import {Drawer} from "./src/navigation/MergedNavigator";
import {View,Text} from "react-native";
const App = () => (
<View style={{flex: 1,backgroundColor: '#293656'}}>
<Drawer />
</View>
);
export default App;
MergedNavigator.js
import {DrawerNavigator,StackNavigator,createBottomTabNavigator} from 'react-navigation';
// stack navigation screens
import DetailScreen from '../screens/detail';
import MainScreen from '../screens/main';
import ForgotScreen from '../screens/ForgotScreen';
import RegisterScreen from '../screens/RegisterScreen';
// tab navigator screens
import LoginScreen from '../screens/Login';
import TabOne from '../screens/tabA';
import TabTwo from '../screens/tabB';
//plain
export const stack = StackNavigator({
DetailScreen:{screen:DetailScreen},
MainScreen:{screen:MainScreen}
},{
initialRouteName:'DetailScreen'
});
const secondStack = StackNavigator({
RegisterScreen:{screen:RegisterScreen},
ForgotScreen:{screen:ForgotScreen}
},{
initialRouteName:'ForgotScreen'
})
export const Tabs = createBottomTabNavigator({
Login:{screen:LoginScreen},
TabOne:{screen:secondStack},
TabTwo:{screen:TabTwo}
},{
animationEnabled:true
})
export const Drawer = DrawerNavigator({
Tabs:{screen:Tabs},
Stack:{screen:stack}
})
And all other imported stack screen has nothing but the title.
What's the problem here with my code? Or is there any better way I can achieve these all 3 Navigators with only react-navigation?
There is an issue with the sub actions being reset inside the Stack which can be seen here
Therefore the workaround for this issue would be to wrap your createBottomTabNavigator inside a createStackNavigator with headerMode: none in order to achieve the desired effect.
Info
By adding a StackNavigator nested directly within a DrawerNavigator, the sub actions will be reset only to the StackNavigator defined and won't affect the child screen states, therefore it won't throw the error, as mentioned in the code
if (route.index !== undefined && route.index !== 0) {
subAction = NavigationActions.reset({
index: 0,
actions: [
NavigationActions.navigate({
routeName: route.routes[0].routeName,
}),
],
});
}
MergedNavigator.js
import ForgotScreen from '../screens/ForgotScreen';
import RegisterScreen from '../screens/RegisterScreen';
// tab navigator screens
import LoginScreen from '../screens/Login';
import TabOne from '../screens/tabA';
import TabTwo from '../screens/tabB';
//plain
export const stack = StackNavigator({
DetailScreen:{screen:DetailScreen},
MainScreen:{screen:MainScreen}
},{
initialRouteName:'DetailScreen'
});
const secondStack = StackNavigator({
RegisterScreen:{screen:RegisterScreen},
ForgotScreen:{screen:ForgotScreen}
},{
initialRouteName:'ForgotScreen'
})
export const Tabs = createBottomTabNavigator({
Login:{screen:LoginScreen},
TabOne:{screen:secondStack},
TabTwo:{screen:TabTwo}
},{
animationEnabled:true
})
const TabStack = createStackNavigator({ //... Adding the Stack here
Tabs: {screen: Tabs}
}, {
headerMode: 'none'
})
export const Drawer = DrawerNavigator({
Tabs:{screen:Tab},
Stack:{screen:stack}
})
Here's a modified Snack with header's enabled
import { StackActions, NavigationActions } from 'react-navigation';
let { navigation } = this.props;
let resetAction = StackActions.reset({
key: undefined,
index: 0,
actions: [NavigationActions.navigate({ routeName: 'YourScreen' })],
});
navigation.dispatch(resetAction);
When you set the key to undefined, the navigator uses the actual stack, not the root.
First of all your main issue is you cann't create more than one StackNavigator() on your code.
Please try different navigator for redirection like below example code.
import {DrawerNavigator,StackNavigator,createBottomTabNavigator,createMaterialTopTabNavigator} from 'react-navigation';
// stack navigation screens
import DetailScreen from '../screens/detail';
import MainScreen from '../screens/main';
import ForgotScreen from '../screens/ForgotScreen';
import RegisterScreen from '../screens/RegisterScreen';
// tab navigator screens
import * as TAB from '../tab';
export const stack = StackNavigator({
DetailScreen:{screen:DetailScreen},
MainScreen:{screen:MainScreen}
},{
initialRouteName:'DetailScreen'
});
const secondStack = createMaterialTopTabNavigator({
RegisterScreen:{screen:RegisterScreen},
ForgotScreen:{screen:ForgotScreen}
},{
initialRouteName:'ForgotScreen'
})
export const Tabs = createBottomTabNavigator({
Login:{screen:TAB.Login},
TabOne:{screen:secondStack},
TabTwo:{screen:TAB.TabB}
},{
animationEnabled:true,
initialRouteName:'Login'
})
export const Drawer = DrawerNavigator({
Tabs:{screen:Tabs},
Stack:{screen:stack}
},
{
animationEnabled:true,
initialRouteName:'Tabs'
})
hope above code snippet is useful for you.
How can I integrate redux with navigation drawer using react navigation in react native. here is my code without redux
import React, { Component } from "react";
import { AppRegistry } from "react-native";
import { StackNavigator, DrawerNavigator } from "react-navigation";
import DrawerMenu from "./containers/DrawerMenu";
import BarChart from "./containers/BarChart";
import PieChart from "./containers/PieChart";
import LineChart from "./containers/LineChart";
const MainScreenNavigator = StackNavigator ({
bChart: { screen: BarChart },
pChart: { screen: PieChart },
lChart: { screen: LineChart }
});
const Drawer = DrawerNavigator (
{
Main: { screen: MainScreenNavigator }
},
{
contentComponent: DrawerMenu,
drawerWidth: 200
}
);
export default Drawer;
Its not suggested to connect React Navigation with Redux (redux-integration). Personally, I never had any problems when they are seperated even when I use several nested navigators. You don't have to keep the navigator in the store. You should consider seperating them.
