@override Future<List<CameraMacOSDevice>> listDevices({ CameraMacOSDeviceType? deviceType, })

Call this method to discover all camera devices.

Implementation

@override

    {CameraMacOSDeviceType? deviceType}) async {
  try {
    final Map<String, dynamic>? args =
        await methodChannel.invokeMapMethod<String, dynamic>(
      'listDevices',
      {
        "deviceType": deviceType?.index,
      },
    );
    if (args == null || args["devices"] == null) {
      throw FlutterError("Invalid args: invalid platform response");
    }
    List<Map<String, dynamic>> devicesList = List.from(args["devices"] ?? [])
        .map((e) => Map<String, dynamic>.from(e))
        .toList();
    List<CameraMacOSDevice> devices = [];
    for (Map<String, dynamic> m in devicesList) {
      CameraMacOSDevice device = CameraMacOSDevice.fromMap(m);
      devices.add(device);
    }
    return devices;
  } catch (e) {
