Disable back button in react navigation

Question

I\'m using react native navigation (react-navigation) StackNavigator. it starts from the Login page throughout the whole lifecycle of the app. I don\'t want to have a back

Answer 1

The SwitchNavigator would be the way to accomplish this. SwitchNavigator resets the default routes and unmounts the authentication screen when the navigate action is invoked.

import { createSwitchNavigator, createStackNavigator, createAppContainer } from 'react-navigation';

// Implementation of HomeScreen, OtherScreen, SignInScreen, AuthLoadingScreen
// goes here.

const AppStack = createStackNavigator({ Home: HomeScreen, Other: OtherScreen });
const AuthStack = createStackNavigator({ SignIn: SignInScreen });

export default createAppContainer(createSwitchNavigator(
  {
    AuthLoading: AuthLoadingScreen,
    App: AppStack,
    Auth: AuthStack,
  },
  {
    initialRouteName: 'AuthLoading',
  }
));

After the user goes to the SignInScreen and enters their credentials, you would then call

this.props.navigation.navigate('App');
