How Display Quill Content Without Extra Line or Space at the End

[Abolfazlnezami2000]

I am encountering an issue where the Quill editor always shows an extra line or space at the end. When I save the editor content and try to display it, I receive an output with {"insert": "\n"} at the end.
If I attempt to remove this, I encounter the error: "Invalid document delta. Document delta must always end with a line-break."

How can I display the Quill editor content without this extra spacing at the end?

Steps to Reproduce

code :

@override
Widget build(BuildContext context) {
  final controller = FleatherController();
  final document = json.decode(data.descriptionField!.getLocalizedStr(App.appLocale)) as List<dynamic>;
  controller.compose(ParchmentDocument.fromJson(document).toDelta());
  return FleatherEditor(
    controller: controller,
    readOnly: true,
    showCursor: false,
  );
}
