Redux integration
It is extremely easy to use Redux in an app with React Navigation. It's basically no different than without React Navigation.
import { Provider } from 'react-redux';
import { NavigationContainer } from '@react-navigation/native';
// Render the app container component with the provider around it
export default function App() {
return (
<Provider store={store}>
<NavigationContainer>
{/* Screen configuration */}
</NavigationContainer>
</Provider>
);
}
Notice that we wrap our components in a Provider
like we'd normally do with react-redux
. Ta da! Now feel free to use connect
throughout your app.
Use a component that is connect
ed in options
Create a component, connect
it to the store, then use that component in the title
.
function Counter({ value }) {
return <Text>Count: {value}</Text>;
}
const CounterContainer = connect(state => ({ value: state.count }))(Counter);
<Screen
name="Test"
component={TestScreen}
options={{ title: () => <CounterContainer /> }}
/>
Pass the state you care about as a param to the screen
If the value isn't expected to change, you can just pass it from a connected component to the other screen as a param.
<Button
title="Go to static counter screen"
onPress={() =>
props.navigation.navigate('StaticCounter', {
count,
})
}
/>
function StaticCounter({ route }) {
return (
<View style={styles.container}>
<Text style={styles.paragraph}>{route.params.count}</Text>
</View>
);
}
So our component will look like this:
<RootStack.Screen
name="StaticCounter"
component={StaticCounter}
options={({ route }) => ({ title: route.params.count })}
/>
Can I store the navigation state in Redux too?
This is not possible. We don't support it because it's too easy to shoot yourself in the foot and slow down / break your app.
However it's possible to use redux-devtools-extension
to inspect the navigation state and actions, as well as perform time travel debugging by using the devtools
package.
