Using onEnter/onExit from Component

[luco]

Is there a way from using onEnter and onExit from component itself?
I mean, I want to call a function from my component every time I enter on it.

I tried using on Scene component, but wasn't lucky.

I wanted to do something similar. Calling Actions.refresh() in the transitioning scene rerenders the new scene so you could put something in componentWillReceiveProps

@luco Have you tried to add onEnter/onExit on containers or on child? It works only for child. I've just added possibility to define them on component level (as static functions), please check.

Shouldn't this be working?

<Scene key="login" component={Login} title="Login" onEnter={this.doSomething} />

[aksonov]

Depends from what is this.doSomething. Just put onEnter={()=>console.log("onEnter!")} to see log

[rochapablo]

Yep, you're right! I may be doing something wrong. Thank you.

I still don't really understand how onEnter works. Is it possible to call a function from the component from there? Is there a tutorial / doc on how to use it?

[aksonov]

Demo is in progress... You may define it as static component function

Is there such event listener for Drawer? I need to listen for Drawer opens/closes. I can't find this in docs.

<Drawer /> is the same as <Scene drawer />. When it opens/closes is the onEnter/onExit event - but you can also use only react-navigation for that with NavigationEvents.

EDIT: This event is available for Drawer only react-native-router-flux@^4.0.2 - previous versions does not support it.

EDIT2: Check out the examples folder - I believe there are something there showing it.
