I was wondering where to put functions that must be executed on the opening of the app. Not on foregrounding. In my case a check whether the user is already signed in or not, so that I can redirect to an AuthenticationScreen if necessary.
The function for the retrieval of the ExponentPushToken, for example, is called in the navigation/RootNavigation.js by default, which feels kind of unintuitive…
What do you think and how do you handle those things?
I have now tried to add the check for the authentication in the componentWillMount of the RootComponent, which works fine. But if the authentication has not been done, I need to redirect to the AuthenticationScreen. The issue is, that in the RootComponent I am not able to use this.props.navigation.navigate(…) to redirect. Do you know how to work this out?
Without having a chance to see your code, it would be difficult to know if the navigation property is provided by the parent correctly. I would try to reorganize some of your code or read more into the docs for react-navigation to see how the property is provided in the first place.
