React Navigation how to get back to specific screens?
I am using react-navigation:^1.0.0-beta.9
, is there a way to go back to a specific screen (and not the previous one)? I also integrated mine react-navigation
with redux
. I looked through the documentation and saw what the back
parameter takes key
, but I don't understand it and tried to put it in the screen name, for example back({ key: 'Screen B' })
, but it doesn't work, probably because it expects key
, which is randomly generated, unless specifically stated.
For example, I have this StackNavigator
Screen A
- Screen B
- Screen C
- Screen D (Current)
Let's say I'm on now Screen D
, and I wanted to go back to Screen B
, how would I achieve it?
I don't want to use navigation.navigate('Screen B')
, because this will add another screen to the stack, not what I expect.

1. Inside, screen D
send some action:
const {navigation} = this.props;
navigation.dispatch({
routeName: 'B',
type: 'GoToRoute',
});
2.Set this action in MyStackNavigator.js
const MyStackNavigator = new StackNavigator(//...);
const defaultGetStateForAction = MyStackNavigator.router.getStateForAction;
MyStackNavigator.router.getStateForAction = (action, state) => {
if (state && action.type === 'GoToRoute') {
let index = state.routes.findIndex((item) => {
return item.routeName === action.routeName
});
const routes = state.routes.slice(0, index+1);
return {
routes,
index
};
}
return defaultGetStateForAction(action, state);
};
and then you can go from screen D
to screen B
directly
