Question: Markdown Formatting Not Applied on First Use in FleatherField

[gitStanda]

I need to have 2 different FleatherFields & I don't want to have 2 toolbars shown at the same time - so depending on the focused field, I show toolbar with selected field's controller.

However, I’m experiencing an issue with both FleatherFields where formatting options (e.g., bold, italics, etc.) are not applied correctly when selected before typing. You can see the issue on the attached video.

It seems like the formatting doesn’t persist until the user types at least one character first. This issue occurs only before any text is entered—after that, the controller behaves normally.

Steps to Reproduce:

1. Tap into a FleatherField.
2. Without typing anything, select bold, italics or any other option from the toolbar.
3. Start typing text.
4. Notice that the formatting options are unchecked, and the text is not formatted as expected.

Expected Behavior: The selected formatting (bold, italics, ...) should be applied correctly from the first character typed after being selected in the toolbar.

My code:

• I tried to extract only the most relevant code.

class _ManualFlashcardScreenState extends ConsumerState<ManualFlashcardScreen> {
  late final FleatherController _frontSideController;
  late final FleatherController _backSideController;
  final FocusNode _frontFocusNode = FocusNode();
  final FocusNode _backFocusNode = FocusNode();
  FleatherController? _activeController;

  @override
  void initState() {
    super.initState();
    _frontSideController = FleatherController(
      document: widget.flashcard != null
          ? ParchmentDocument.fromDelta(widget.flashcard!.frontSide.toDelta())
          : ParchmentDocument(),
    );
    _backSideController = FleatherController(
      document: widget.flashcard != null
          ? ParchmentDocument.fromDelta(widget.flashcard!.backSide.toDelta())
          : ParchmentDocument(),
    );

    _frontFocusNode.addListener(_updateActiveController);
    _backFocusNode.addListener(_updateActiveController);

    if (widget.flashcard == null) _frontFocusNode.requestFocus(); // creating flashcard, not editing
  }

  void _updateActiveController() {
    setState(() {
      if (_frontFocusNode.hasFocus) {
        _activeController = _frontSideController;
      } else if (_backFocusNode.hasFocus) {
        _activeController = _backSideController;
      }
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        children: [
          FleatherField(
            controller: _frontSideController,
            focusNode: _frontFocusNode,
            enableSuggestions: false,
          ),
          FleatherField(
            controller: _backSideController,
            focusNode: _backFocusNode,
            enableSuggestions: false,
          ),
          if (_activeController != null)
            FleatherToolbar.basic(controller: _activeController!),
        ],
      ),
    );
  }
}

Question

Is this behavior expected with FleatherField, or is there something wrong in my code that might be causing it? Any advice on how to resolve this would be appreciated!

Might be a bug as well, not sure to be honest

BTW just tested this out on iOS simulator and it works. So maybe the issue is just on Android or the Emulator itself?

Encountering the same situation, it is necessary to input once in advance on Android to enable the style, while iOS does not require this.
