Controlling initial state of a destination StackNavigator from initial SwitchNavigator screen

Question

I have a SwitchNavigator 'switch'. It's initial state 'root' is a screen component that is just loading state and determining the correct initial route (A, or B) of a StackNavigator 'stack'.

--switch
     --root
     --stack
        -A
        -B

what's the right way for the 'root' component to tell the Switch Navigator to switch to 'stack' and then start with either 'A or B' conditionally?

Answer 1

In the root component, when your job is done, just call navigation.navigate like this:

this.props.navigation.navigate(condition ? 'A' : 'B');
