Answer 1

i was using remember { } wrong, i was trying to use it in dicString function to remember obtained string. That caused the issue. I fixed that by adding the resource id to the remember function as parameter. remember( id ) { }

Answer 2

I had this happen when returning from a composable due to lack of data from within the construction of a composable.

val dataOrNull by viewModel.data.collectAsState(null)

Box {
    MyComposable(
        data = dataOrNull ?: return
    )
}

I fixed this by returning prior to constructing the tree

val dataOrNull by viewModel.data.collectAsState(null)

val data = dataOrNull ?: return

Box {
    MyComposable(
        data = data
    )
}

Answer 3

I experienced the same issue on compose version compose_version = '1.1.0' The fix was to remove the return statement from a composable function. Example:

@Composable
fun Foo() {
    if (true) return // convert to else statement
    Text(text = "foo")
}
