Proper way of using onEnter / success?

[EnriqueDev]

Hi! First of all congratulations for this awesome work you have done so far, it has been very useful. I would like to know what is the correct way to use the onEnter/success props of the scene and if can I call component methods from there.

Thanks.

PD: If someone explains it properly I could maybe write a doc/example and make a pull request.

You can call static function onEnter of component or just pass it as prop to Scene. If it returns non-null value RNRF makes automatic transition to scene defined by success (failure otherwise)

Sorry, no access to component methods - it just accesses to your navigation state, like navBar static methods.

So inside my component I should call:

static onEnter = (callback) => {
    callback()
}

?

[aksonov]

Current state params are passed to onEnter. So you could try to pass callback, like
Actions.login({callback}) and then your onEnter will be executed with {callback} param.

My main problem here is that as ReactNavigation does not unmount tabs, all the component's lifecycle methods are not called and it's impossible to perform requests in the usual place. Using the current API v4 what would you recommend as an approach (not code, I just need some guidance)?.

Thanks for your time!

I believe onEnter is way to go. Another way is to use type=replace instead of tabs, so your scenes will be unmounted.

good enough. Is there a way to set the lazy prop when using TabNavigator?

[aksonov]

Yes, just pass lazy prop
