the following error occurs when using flutter camera plugin, I've added the permission to the manifest file, and still not working.

You can also now use this plugin : CamerAwesome

Official plugin has been quite abandonned. This plugin includes flash, zoom, auto focus... and no initialisation required.

I also received this error when using Flutter camera plugin example when I changed it from CameraController.startVideoRecording() to CameraController.startImageStream(Function<CameraImage>).

To resolve this issue I commented/removed imageFormatGroup: ImageFormatGroup.jpeg at CameraController instantiation:

controller = CameraController(
  cameraDescription,
  ResolutionPreset.medium,
  enableAudio: enableAudio,
  //imageFormatGroup: ImageFormatGroup.jpeg, //remove or comment this line
);

This may happen because CameraImage received at startImageStream uses YUV image encoding.
