Question

Has anyone had any luck embedding compose in a Flutter application Trying to sneak in a cheeky bit in an AlertDialog via a `ComposeView ` but getting `java lang IllegalStateException ViewTreeLifecycleOwner not found from androidx appcompat widget AlertDialogLayout`

czuckie · Answer

I did end up creating my own `FlutterActivityAppCompat` just incase it was some AppCompatActivity stuff that needed to be going but that didn t seem to help disappointed

Ian Lake · Answer

Keep in mind that the dialog s view is in a totally separate window from the activity s view hierarchy so nothing in the activity level is going to help the dialog s view needs to have a LifecycleOwner set

I hope this is to join the compose side fully smirk

< Ian Lake> I did not keep that in mind How does a dialog typically get its lifecycle owner set then For now I ve thrown in the towel FWIW I really would like this to be compose having done compose for a good while now going to Flutter is like going from Kotlin to Java Like I can see the structural similarities but crikey so much typing

Ian Lake · Answer

Compose s `Dialog` composable pulls the owners from the activity which isn t perfect but good enough tm in just about every case <https cs android com androidx platform frameworks support + androidx main compose ui ui src androidMain kotlin androidx compose ui window AndroidDialog android kt l=355|https cs android com androidx platform frameworks support + androidx main compose lin androidx compose ui window AndroidDialog android kt l=355>

Ian Lake · Answer

That does assume that your activity implements `ComponentActivity` or its subclasses `FragmentActivity` or `AppCompatActivity` which do have those owners set for you already

Ian Lake · Answer

Which means you could set each owner just by calling `ViewTreeLifecycleOwner set yourDialogLayout yourActivity ` and `yourDialogLayout setViewTreeSavedStateRegistryOwner yourActivity `

thanks for the explanation Ian I might just give it a go and see if I can t smuggle some compose into the app that way
