I'm using a BasicTextField with an annotated string to make a rudimentary rich text editor. However, the styles keep getting removed whenever the value is updated via the onValueChange callback. Am I missing something about the functionality of the BasicTextField? Code in thread.

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            
            var value by remember {
                mutableStateOf(TextFieldValue(
                    annotatedString = buildAnnotatedString {
                        withStyle(SpanStyle(fontWeight = FontWeight.Bold)) {
                            append("Bolded")
                        }
                        append(" should not be removed")
                    },
                    selection = TextRange(28)
                ))
            }

            BasicTextField(value = value, onValueChange = { value = it })

        }
    }
}

Compose doesn't support rich text editing yet. We use this ticket to track this work https://issuetracker.google.com/issues/139320381
Feel free to vote or drop a comment with your use case

Oh. That's surprising considering the BasicTextField interface allows for, and properly renders, styled text.

We haven't done the implementation but we made sure that we have API in place.

Thank you for sharing these @Anastasia [G]! I know building support for that is definitely going to be an undertaking. I have a working prototype on desktop using a swing-based component wrapped inside compose and I can put the mobile version on hold for now. Is building this functionality something that's considered a high priority? Or is it a bit too use-case specific to warrant attention?
