[reamal]

My issue is about [Mobile]
I try clean content in the QuillEditor.

[reamal]

change _controller value is work, but should have a better way ?
setState(() { _controller = QuillController.basic(); });

  void clean() {
    replaceText(0, plainTextEditingValue.text.length-1, '', TextSelection.collapsed(offset: 0));
  }
