updateClipTrim method

void updateClipTrim(int index, Duration start, Duration end)

Sets the clip's in/out points in file time. Image clips have no source length, so for them the range only sets the display duration.

Implementation

void updateClipTrim(int index, Duration start, Duration end) {
  if (index < 0 || index >= _clips.length) return;
  final clip = _clips[index];

  if (clip.isImage) {
    final length = end - start;
    final duration = length < const Duration(milliseconds: 100)
        ? const Duration(milliseconds: 100)
        : length;
    _clips[index] = clip.copyWith(
      duration: duration,
      startTime: Duration.zero,
      endTime: duration,
      clearConvertedVideoFile: true,
    );
  } else {
    final max = clip.duration > Duration.zero ? clip.duration : end;
    var s = start < Duration.zero ? Duration.zero : start;
    var e = end > max ? max : end;
    if (e - s < const Duration(milliseconds: 100)) {
      e = s + const Duration(milliseconds: 100);
      if (e > max) {
        e = max;
        s = e - const Duration(milliseconds: 100);
        if (s < Duration.zero) s = Duration.zero;
      }
    }
    _clips[index] = clip.copyWith(
      startTime: s,
      endTime: e,
    );
  }
  _clips[index].markEdited();
