takeSnapshot method

Future<UCapturedPhoto?> takeSnapshot({ UPhotoFormat format = UPhotoFormat.jpeg, int quality = 90, })

Grabs the current preview frame as an image without a full capture cycle. Much faster than takePhoto and silent, at preview resolution.

Implementation

Future<UCapturedPhoto?> takeSnapshot({UPhotoFormat format = UPhotoFormat.jpeg, int quality = 90}) async {
  final int? id = _sessionId;
  if (id == null) return null;
  try {
    final Map<Object?, Object?>? raw = await UCameraChannel.invokeMap("takeSnapshot", <String, Object?>{
      "sessionId": id,
      "format": format.name,
      "quality": quality,
    });
    return raw == null ? null : UCapturedPhoto.fromMap(raw);
  } on UCameraException catch (error) {
    _fail(error);
    return null;
  } catch (error) {
    _fail(UCameraException(code: UCameraErrorCode.unknown, message: "$error"));
    return null;
  }
}
