Exposing a `suspend fun` from a nested Fragment to...

Exposing a suspend fun from a nested Fragment to be called by the parent Fragment. What’d happen if the nested Fragment gets killed before the suspension point returns?

[octylFractal]

depends on who's calling the suspend fun, if it runs in the nested Frag context then it will be canceled, if it runs in the parent Frag context then it won't

[Gabriel Feo]

It’d be called from the parent fragment. Do you know a way to simulate a Fragment being killed, without the Activity being killed?

[Gabriel Feo]

This library is an example, it attaches a child fragment to a parent fragment and suspends for the permission results: https://github.com/sagar-viradiya/eazypermissions/blob/master/coroutinespermission/src/main/java/com/eazypermissions/coroutinespermission/PermissionManager.kt

[octylFractal]

the deferred is a different case

[octylFractal]

if the fragment is removed from memory, it's likely that the deferred's continuation would be removed too

[octylFractal]

thus the coroutine would never resume

@sagar-viradiya Q on your library above ^^
