update mask blocking backspace on iOS

[JulioCRFilho]

Hi guys, as the title says, I'm not being able to delete any character in the input field.

Here's the code:
doc.addListener(() { doc.updateMask( doc.text.length >= 15 ? '00.000.000/0000-00' : '000.000.000-000'); });

This problem only occurs on iOS simulator, I hadn't the chance to test it on a device yet. I even tried it on different versions of iOS simulator but nothing changed.

Any thoughts on this?

Same thing is happening here when using beforeChange (just like the documentation).

It works fine on Android devices but on iOS I can't delete anything.

_controller.beforeChange = (String previous, String next) {
      if (next.length > 9)
        _controller.updateMask('000.000.000-00');
      else
        _controller.updateMask('000000-0');
      return true;
};
