Trying to select an empty text with a ParagraphStyle on a TextField causes a crash.
This crash occurs with both TextField and BasicTextField.
- Place the composable function below.
TextField(
value = TextFieldValue("hoge\n"),
onValueChange = {},
modifier = Modifier
.fillMaxWidth()
.height(200.dp),
visualTransformation = {
val styledText = buildAnnotatedString {
append(it.text)
addStyle(
start = 5,
end = 5,
style = ParagraphStyle(),
)
}
TransformedText(
styledText,
OffsetMapping.Identity,
)
},
)- Long-press on the second line of the text field.
- The app will crash with an FATAL EXCEPTION like below.
