问题 I'm building a React Native app with TypeScript. I'm doing my component tests using Jest and Enzyme. I'm also using React Navigation I'm struggling to write the unit test for clicking my button.

问题 I have a React Native application which I have implemented. Currently the app opens up on a loading screen which after mounting checks the firebase.auth().onAuthStateChanged(...) feature. The app basically decides whether or not to got to the login screen or to main screen depending on whether or not the user is already authenticated.

问题 I am creating a react native app using expo, and I am creating a dropdown in the header. On iOS the dropdown works as desired, and goes 'above' the main content, while on Android it is clipped or goes 'under'. I am not sure if in reality iOS is acting strange, or Android is.

问题 Is it possible to nest a Tab Navigator inside of a Drawer Navigator and then navigate to a specific tab from the Drawer? Consider this very basic set up: const PrimaryNav = createBottomTabNavigator({ ScreenOne, ScreenTwo }) export const DrawerNavigator = createDrawerNavigator({ Home: { screen: PrimaryNav, drawerLabel: 'Option 1', }, Investment: { screen: PrimaryNav, drawerLabel: 'Option 2', } }) Obviously, this set up will just resolve to the first item in the TabNav regardless of which

问题 I have just implemented an Auth stack and having an issue with my TabNavigator - when I click my second "Favourites" tab which is in my tab navigator and referenced the MainNavigator within my switch I get the message There is no route named 'Favourites' in the navigator with the key 'Dashboard.
