SetLooping is not working, and play makes StackOverflow

[com8599]

env

ffmpeg_kit_flutter: ^6.0.3
flutter_video_info: ^1.3.2
video_trimmer: ^3.0.1

I want to seek to _startValue and play when end dragging rightcircle, but when I drag rightcircle, it play at _endValue and not looping.
And I make this code.
But, the code makes stackoverflow.

TrimViewer(
  trimmer: trimmer,
  viewerHeight: 56.0,
  viewerWidth: MediaQuery.of(context).size.width,
  maxVideoLength: const Duration(seconds: 30),
  onChangeStart: (value) => _startValue = value,
  onChangeEnd: (value) => _endValue = value,
  onChangePlaybackState: (value) => setState(() {
    _isPlaying = value;
    if (!_isPlaying) {
      trimmer.videoPlayerController
          ?.seekTo(Duration(seconds: _startValue.toInt()));
      // trimmer.videoPlayerController?.play(); <= it makes stackoverflow
    }
  }),
),

stackoverflow message

I think that there are infinite loop in TrimViewer,
Can you fix this problem?

I found out a solution

  void _onDragUpdate(DragUpdateDetails details) {
    if (!_allowDrag) return;

    if (_dragType == EditorDragType.left) {
      _startCircleSize = widget.editorProperties.circleSizeOnDrag;
      if ((_startPos.dx + details.delta.dx >= 0) &&
          (_startPos.dx + details.delta.dx <= _endPos.dx) &&
          !(_endPos.dx - _startPos.dx - details.delta.dx > maxLengthPixels!)) {
        _startPos += details.delta;
        _onStartDragged();
      }
    } else if (_dragType == EditorDragType.center) {
      _startCircleSize = widget.editorProperties.circleSizeOnDrag;
      _endCircleSize = widget.editorProperties.circleSizeOnDrag;
      if ((_startPos.dx + details.delta.dx >= 0) &&
          (_endPos.dx + details.delta.dx <= _thumbnailViewerW)) {
        _startPos += details.delta;
        _endPos += details.delta;
        _onStartDragged();
        _onEndDragged();
      }
    } else {
      _endCircleSize = widget.editorProperties.circleSizeOnDrag;
      if ((_endPos.dx + details.delta.dx <= _thumbnailViewerW) &&
          (_endPos.dx + details.delta.dx >= _startPos.dx) &&
          !(_endPos.dx - _startPos.dx + details.delta.dx > maxLengthPixels!)) {
        _endPos += details.delta;
        _onStartDragged(); <- my code
        _onEndDragged();
      }
    }
    setState(() {});
  }
...
/// Drag gesture ended, update UI accordingly.
void _onDragEnd(DragEndDetails details) {
  setState(() {
    _startCircleSize = widget.editorProperties.circleSize;
    _endCircleSize = widget.editorProperties.circleSize;
    if (_dragType == EditorDragType.right) {
      videoPlayerController
          .seekTo(Duration(milliseconds: _videoStartPos.toInt())); <- my code
         //  .seekTo(Duration(milliseconds: _videoEndPos.toInt())); <- pure code
    } else {
      videoPlayerController
          .seekTo(Duration(milliseconds: _videoStartPos.toInt()));
    }
  });
}

please fix the line
