thumbnailData static method

Future<Uint8List?> thumbnailData({
  1. required String video,
  2. Map<String, String>? headers,
  3. ImageFormat imageFormat = ImageFormat.PNG,
  4. int maxHeight = 0,
  5. int maxWidth = 0,
  6. int timeMs = 0,
  7. int quality = 10,
})

Generates a thumbnail image data in memory as UInt8List, it can be easily used by Image.memory(...). The video can be a local video file, or an URL repreents iOS or Android native supported video format. Specify the maximum height or width for the thumbnail or 0 for same resolution as the original video. The lower quality value creates lower quality of the thumbnail image, but it gets ignored for PNG format.

Implementation

static Future<Uint8List?> thumbnailData({
  required String video,
  Map<String, String>? headers,
  ImageFormat imageFormat = ImageFormat.PNG,
  int maxHeight = 0,
  int maxWidth = 0,
  int timeMs = 0,
  int quality = 10,
}) async {
  assert(video.isNotEmpty);
  final reqMap = <String, dynamic>{
    'video': video,
    'headers': headers,
    'format': imageFormat.index,
    'maxh': maxHeight,
    'maxw': maxWidth,
    'timeMs': timeMs,
    'quality': quality,
  };
  return await _channel.invokeMethod('data', reqMap);
