Android ComposeView, Composable is gone upon returning to Screen from stack

[emitchel]

Description

tldr; Jetpack ComposeViews do not maintain state or recompose upon returning to a Screen with a ComposeView driving a component of the Screen.

Suppose you have three screens, screens A, B and C

Screen B has a View that links to a ComposeView(..) from Android
Navigating to Screen C, then returning to Screen B, the ComposeView driven component is gone

According to this issue tracker, https://issuetracker.google.com/issues/284424175, the issue lies within how ScreenFragment recycles the views

Project to repro (thanks to @thevoiceless) - https://github.com/thevoiceless/RN-Compose-Playground

Steps to reproduce

1. Use a SimpleViewManager to wrap a ComposeView
2. Build the ComposeView with a simple Text(..)
3. But that ComposeView in Screen A
4. Navigate to Screen B
5. Navigate BACK to Screen A
6. Notice that the ComposeView is gone but the wrapper of the view itself is still in the hierarchy

Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

Hi @emitchel, thanks for filling this issue!
Yeah, using Jetpack Compose along React Native Screens have already been heavily discussed in our internal Screens Team 😄 We've got this task of supporting Jetpack Compose on our agenda. Thanks!
