BufferQueueProducer spam. Camera does not get closed properly.

[nietsmmar]

After taking a picture this is spammed in my logs continuesly:

BufferQueueProducer(17233): [SurfaceTexture-0-17233-2](this:0x7c579000,id:4,api:1,p:17233,c:17233) queueBuffer: slot 1 is dropped, handle=0x802a4640

it won't stop to spam this. And I can't open CameraSnapScreen again. If I do it won't find the camera. So for me it seems like the camera is not closed properly?

my code:

Navigator.of(navContext)
    .push(
  MaterialPageRoute(
    builder: (context) => CameraSnapScreen(
        cameraType: CameraType.back, appBar: AppBar(title: Text("Take Picture"))),
  ),
)
