reorder method

Future<String> reorder(String playlistId, { required int rangeStart, required int insertBefore, int rangeLength = 1, String? snapshotId, })

Reorders items in a playlist with playlistId and its optional snapshotId against which you want to make the changes.

rangeStart is the position of the first item to be reordered.

insertBefore is the position where the item(s) should be inserted. To reorder the item(s) to the end of the playlist, simply set insertBefore to the position after the last item.

rangeLength is the amount of items to be reordered. Defaults to 1 if not set. The range of items to be reordered begins from the rangeStart position, and includes the rangeLength subsequent items.

If snapshotId is null, the current id is used.

Returns a new snapshotId for the playlist.

Implementation

Future<String> reorder(String playlistId,
    {required int rangeStart,
    required int insertBefore,
    int rangeLength = 1,
    String? snapshotId}) async {
  assert(rangeStart >= 0, 'rangeStart out of bounds');
  var body = <String, dynamic>{
    'range_start': rangeStart,
    'insert_before': insertBefore,
    'range_length': rangeLength,
  };
  if (snapshotId != null) {
    body['snapshot_id'] = snapshotId;
  }
  return _reorderOrReplace(playlistId, jsonEncode(body));
}
