initialize method

Future<void> initialize({ double? aspectRatio, })

Attempts to open the given video File and load metadata about the video.

Update the trim position depending on the maxDuration param Generate the default cover _selectedCover Initialize minCrop & maxCrop values base on aspectRatio

Throw a VideoMinDurationError error if the minDuration is bigger than videoDuration, the error should be handled as such:

 controller
    .initialize()
    .then((_) => setState(() {}))
    .catchError((error) {
  // NOTE : handle the error here
}, test: (e) => e is VideoMinDurationError);

Implementation

Future<void> initialize({double? aspectRatio}) async {
  await _video.initialize();

  if (minDuration > videoDuration) {
    throw VideoMinDurationError(minDuration, videoDuration);
  }

  _video.addListener(_videoListener);
  _video.setLooping(true);

  // if no [maxDuration] param given, maxDuration is the videoDuration
  maxDuration = maxDuration == Duration.zero ? videoDuration : maxDuration;

  // Trim straight away when maxDuration is lower than video duration
  if (maxDuration < videoDuration) {
    updateTrim(
        0.0, maxDuration.inMilliseconds / videoDuration.inMilliseconds);
  } else {
    _updateTrimRange();
  }

  cropAspectRatio(aspectRatio);
  generateDefaultCoverThumbnail();
