Deep linking support

Providing a way for the deep linking support in the boilerplate code.

Describe the solution you'd like
I wanted to implement the deep linking support in the boilerplate. Therefore I made below adjustments in the code we have:

— Provided we have another screen available where we want to implement deep linking support.
— In the App/Navigators/AppNavigator.js file, we would need to define the screen name in the stack navigator. Along with that, we would need to supply path attribute to define a unique screen name as per the code segment below:

const StackNavigator = createStackNavigator(
    {
      SplashScreen: SplashScreen,
      MainScreen: {
        screen: ExampleScreen,
      },
      ChatScreen: {
        screen: ChatScreen,
        path: 'chat', // this attribute defines deep linking path
      },
  },
  {
    initialRouteName: 'SplashScreen',
    headerMode: 'none',
  }
)

— Then we would need to set the host in the App/Containers/Root/RootScreen.js and the same host needs to be set in the AppNavigator component props as per the code segment below:

render() {
    //Deep linking prefix
    const prefix = 'thecodingmachine://';

    return (
      <View style={styles.container}>
        <AppNavigator
          uriPrefix={prefix}
          // Initialize the NavigationService (see https://reactnavigation.org/docs/en/navigating-without-navigation-prop.html)
          ref={(navigatorRef) => {
            NavigationService.setTopLevelNavigator(navigatorRef)
          }}
        />
      </View>
    )
  }
}

— As a next step, we would need to set the host and scheme in Android manifest file. And for iOS, we would need to set the same in the Info tab in the xcodeproject.

Describe alternatives you've considered
— That was the simplest solution I could manage, but happy to explore and adapt the code.
— @AurelGit - happy to prep this solution as PR if you think it will be fruitful. Thanks.

Hey @saurabhd !

Sounds perfect :) We did it the same way on our projects, and it could be useful to have it in the boilerplate directly.

We will be very happy to have the PR :)

Thanks !
