Hi folks, is there a substitute for ViewTreeObserver.OnPreDrawListener in Compose? Looking for a way to delay startup due to data initialization. Was looking on https://developer.android.com/about/versions/12/features/splash-screen but can’t connect it with compose.

reading the example, I'm pretty sure the compose equivalent is :

[nitrog42]

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContent { 
        val isReady by viewModel.isReady
        if(isReady) {
            //The composable of your app
        }
    }
}

Imho the result of this code will be a blank screen 🙂

Not on Android 12

For lower versions, you can use the compat lib (https://developer.android.com/about/versions/12/splash-screen-migration#splashscreen_compat_library)

However, I did not find a way to use the Splash Screen API with Compose and custom splash screen animations

Thanks, it’s still something! 👍

File a bug! I was just talking to the dev that implements this and they said to please file a bug. But file a bug and link it and I will send it to them!
