Camera - MissingPluginException(No implementation found for method requestPermissions on channel flutter.baseflow.com/permissions/methods

I receive this error message once I am trigger the camera.

MissingPluginException (MissingPluginException(No implementation found for method requestPermissions on channel flutter.baseflow.com/permissions/methods))

It occurs on the Permission.camera.request in the below codes

Future<void> _startCameraStream() async {
    final request = await Permission.camera.request();
    if (request.isGranted) {
      await BodyDetection.startCameraStream(
        onFrameAvailable: _handleCameraImage,
        onPoseAvailable: (pose) {
          if (!_isDetectingPose) return;
          _handlePose(pose);
        },
        onMaskAvailable: (mask) {
          if (!_isDetectingBodyMask) return;
          _handleBodyMask(mask);
        },
      );
    }
  }```
