Using mobx store in react-navigation createStackNavigator

问题

I would like to use Mobx store variable in createStackNavigator in react-navigation. Specifically, I would like to change the initial route dynamically (so that user can change the initial screen) using the store. would this be possible? Something in the line of...

const stack = createStackNavigator({
Home:{
   ...
},
{
  initialRouteName: this.props.store.initialScreen
{
})

Because this is not a class, I cannot integrate mobx store. Any ideas to change the initialRoute dynamically is appreciated! Thanks

You can have class-based StackNavigator this way:

class YourStack extends React.Component {
  render() {
    const { initialScreen } = this.props.store;

    const RouteConfigs = {
      //
    };

    const NavigatorConfigs = {
      initialRouteName: initialScreen,
    };

    const Stack = createStackNavigator(RouteConfigs, NavigatorConfigs);
    return <Stack />;
  }
}
