Integration with stackNavigator
Hi,
How can i implement stack navigator in SceneMap instead of passing the component name.
In SceneMap it only accepts the react component not the stack navigator which is causing this.props.navigation undefined in nested component.
like i want to pass it in similar way.
const HomeNavigator = createStackNavigator( { Home: HomeScreen, Details: DetailsScreen }, { initialRouteName: "Home" } );
_renderScene = SceneMap({ '1': HomeNavigator, '2': Screen2, '3': Screen3, '4': Screen4, '5': Screen5, '6': Screen6 });
It only accepts the react class component not the StackNavigator.
Hi @phonegap20 - sorry for the delay in getting back to you. We do this today and it works well. Here is how I do it. Its really simple, just pass a function in like this:
_renderScene = SceneMap({
'1': () => HomeNavigator
...
Thanks for your feedback.
Can you share the complete working example please ?
I am sorry to inform you that i also tried it at my end and SceneMap is from react-native-tab-view library and does not exist in react-native-vertical-tab-view.
Kindly share a working example.
Thanks a lot in advance !
React native tab view is a dependency of this project, but this project exports it as well. Here is our implementation, it may be a bit more complex then you looking for because we also use react-native-web and enable different tabs on production/staging versus development/preview environments, but you can see our implementation here. Note many of the imported screens are other navigators like Stack and Tabs:

// treated as 'any' until we can remedy this. If you need to edit this file
// uncomment the [untyped] section of flowconfig so that flow will provide
// you meaningful type check feedback during development. Unfortunately, you
// need to enable the [untyped] section otherwise jenkins will fail the build
// due to the RNTV flow errors.
