Is State<T> only available for recompose in Android Studio Compose?

Question

I have read the article State and Jetpack Compose.

I see the UI will be recomposed automatically when a State<T> variable is changed in Android Studio Compose.

Does it mean the State<T> is unique variable who can recompose UI automatically ? and must other types such as LiveData, Flow be convert to a State in order to update UI automatically?

Answer 1

Yes, you have to convert them as mentioned in the docs.

Key Point: Compose will automatically recompose from reading State objects.

If you use another observable type such as LiveData in Compose, you should convert it to State before reading it in a composable using a composable extension function like LiveData.observeAsState().
