Args: autofocusSeconds (int?): The number of seconds to autofocus. Defaults to 3. quality (PhotoQuality): The quality of the photo. Defaults to PhotoQuality.medium. autofocusType (AutoFocusType): The type of autofocus. Defaults to AutoFocusType.average.

Returns: Future

Throws: Exception: If the photo capture fails.

Implementation

    throw Exception("Cannot take photo via SDK without library helpers");
  }
  if (!isAwake) {
    await frame.runLua("frame.camera.wake()", checked: true);
    await Future.delayed(const Duration(milliseconds: 500));
    isAwake = true;
  }

  final response =
      frame.bluetooth.waitForDataOfType(FrameDataTypePrefixes.photoData);
  await frame.runLua(
      "cameraCaptureAndSend(${quality.value},${autofocusSeconds ?? 'nil'},'${autofocusType.name}')");
  final imageBuffer = await response;
