flutter web - html_editor_enhanced throwing error when try to change the font-family or font size

Question

found the answer of the problem

Here is the code for my Html editor. which is running perfectly, But when I try to change the font size or type, in total whenever I click on any drop down menu it throwing error in web, but working perfectly in Android.

Update :: I found out that, It's a bug with the package: they have mentioned it there. use this method, solves the problem and works fine. The current workaround is to build and/or run your Web app with flutter run --web-renderer html and flutter build web --web-renderer html.

HtmlEditor(
                controller: controller, //required
                htmlToolbarOptions: const HtmlToolbarOptions(
                  dropdownMenuMaxHeight: 100,
                  dropdownMenuDirection: DropdownMenuDirection.down,
                  dropdownItemHeight: 60,
                ),

                htmlEditorOptions: const HtmlEditorOptions(
                  hint: "Your text here...",
                  autoAdjustHeight: true,
                  spellCheck: true,
                  adjustHeightForKeyboard: true,
                  androidUseHybridComposition: true
                ),
                otherOptions: const OtherOptions(height: 400, decoration: BoxDecoration()),
              ),

This is the image of the HtmlEditor code output:

Whenever I try to change the fontsize or click on any dropdown menu: this error is showing from the focus_manager.dart- file

  // Request that an update be scheduled, optionally requesting focus for the
  // given newFocus node.
  void _markNeedsUpdate() {
    assert(_focusDebug('Scheduling update, current focus is $_primaryFocus, next focus will be $_markedForFocus'));
    if (_haveScheduledUpdate) {
      return;
    }
    _haveScheduledUpdate = true;
    scheduleMicrotask(_applyFocusChange);
  }
