iOS crash when deleting a chip with the keyboard

[Axort]

Works great! But there's an issue (only in iOS):
When pressing the keyboard's delete key after a chip, the app crashes. This is the log:

*** First throw call stack:

I think is a Flutter issue and not a problem with this package because I can replicate this in any TextField when trying to delete this >`< character. But I don't know if you have noticed this and if you know the solution to this crash.

Thanks!

i am also facing the same issue

[taljacobson]

does this issue still exist?

[agordeev]

Yes, it does.
Is there any way to prevent the user from deleting symbols by keyboard? This issue is actually a blocker from using the package in any real app on iOS.

Disabling composing in the TextEditingValue stops the crash on iOS.

void _updateTextInputState() {
    final text = String.fromCharCodes(_chips.map((_) => kObjectReplacementChar));
    _value = TextEditingValue(
      text: text,
      selection: TextSelection.collapsed(offset: text.length),
      //composing: TextRange(start: 0, end: text.length),
    );
    if (_connection == null) _connection = TextInput.attach(this, TextInputConfiguration());
    _connection.setEditingState(_value);
  }

Hi all,
Kindly confirm if this issue is fixed, I've merged a fix by @dgsc-fav.

Hi, looks like this has been fixed. I recommend removing the issue from the Package home page, as it looks like it is still a problem?
