Question: Is there any suitable way to unsubscribe event on tab change

[sadi304]

Hello,
I am aware of the issue that component life cycle hooks don't get called if a tab is rendered already. I have an event in a tab (Shake Event), the problem is even when i switch the tab the event is already subscribed as componentwillunmount is never called from that screen (that leads to no remove listener of the event to be called). So in other screen the event is occuring also. I am asking for help if there's any suitable way to handle this scenario. I am not using redux. TIA

Have you tried using the tabBarOnPress to take care of the issue?

@spencercarli , there is a problem in that case. If backbutton is pressed or again home tab then the event is not instantiated again . No idea why this is happening .

Can you put together a demo of the behavior you're seeing? I'm not sure I'm following

okay i will post the code . later .

you can use this.props.navigation.addListener for this! https://reactnavigation.org/docs/navigation-prop.html#addlistener-subscribe-to-updates-to-navigation-lifecycle
