Method `onChange` is called when widget initializes

[zjamshidi]

I'm using SleekCircularSlider in a StreamBuilder to show the audio player's progress. Also, users could use the slider to seek the player. The problem is that method onChange is called even when the user is not selecting the slider. Here is my code:

  Widget positionIndicator(MediaItem mediaItem, PlaybackState state,
      AudioProcessingState processingState) {
    if (processingState == AudioProcessingState.none) {
      return SleekCircularSlider(
          appearance: CircularSliderAppearance(
              spinnerMode: true,
              size: 225,
              customWidths: CustomSliderWidths(trackWidth: 4, progressBarWidth: 13)));
    }
    double seekPos;
    return StreamBuilder(
      stream: Rx.combineLatest2<double, double, double>(
          _dragPositionSubject.stream,
          Stream.periodic(Duration(milliseconds: 200)),
              (dragPosition, _) => dragPosition),
      builder: (context, snapshot) {
        double position =
            snapshot.data ?? state.currentPosition.inMilliseconds.toDouble();
        double duration = mediaItem?.duration?.inMilliseconds?.toDouble();
        print("positionIndicator $position/$duration ${state.processingState}");
        return Column(
          children: [
            if (duration != null &&
                !(position == 0 && state.processingState != AudioProcessingState.ready))
              SleekCircularSlider(
                appearance: CircularSliderAppearance(
                    size: 225,
                    startAngle: 270,
                    angleRange: 360,
                    customWidths:
                    CustomSliderWidths(trackWidth: 4, progressBarWidth: 13)),
                min: 0.0,
                max: duration,
                initialValue: seekPos ?? max(0.0, min(position, duration)),
                innerWidget: (double percentage) => Text(''),
                onChange: (double value) {
                  print('on change');
                  _dragPositionSubject.add(value);
                },
                onChangeEnd: (value) {
                  print('on change end');
                  AudioService.seekTo(Duration(milliseconds: value.toInt()));
                  seekPos = value;
                  _dragPositionSubject.add(null);
                },
              ),
            if (duration == null ||
                (position == 0 && state.processingState != AudioProcessingState.ready))
              SleekCircularSlider(
                  appearance: CircularSliderAppearance(
                      spinnerMode: true,
                      size: 225,
                      customWidths:
                      CustomSliderWidths(trackWidth: 4, progressBarWidth: 13))),
          ],
        );
      },
    );
  }

despite the documentation mentioned:

onChangeOnChange(double value) ... Called during a drag when the user is selecting a new value for the slider by dragging.

Hmm, that's strange... I will look into when I finally find time to work on it again :)

For me either.

It has been fixed in v. 1.2
