Flutter CameraPreview is blurry, noisy, and zoomed in

Question

I have a Google Pixel 3 and am using Flutter's camera plugin at version 0.8.1.

CameraPreview is blurry, noisy, zoomed in, and generally looks worse than Android's camera app.

Android Camera App:

Flutter CameraPreview:

This is how I'm instantiating the CameraController:

final cameras = await availableCameras();
final controller = CameraController(
  cameras[0],
  ResolutionPreset.veryHigh,
  enableAudio: false,
  imageFormatGroup: ImageFormatGroup.yuv420,
);

I tried all 4 cameras:

• Camera 0 is on the front and is the one in question
• Camera 1-3 is on the back and they are all the same. Their quality is similar to Android's Camera App.

Anyone run into this issue?

Experiencing the same issue. Made any progress resolving this? – Beerbohm

Did you ever fix this? – Simplicity

Woof, still no fix? This seems like it may possibly be caused by an incorrect aspect ratio. OP, did you still have the same issue after the pictures were taken? – Luckin

I have the same problem. Camera plugin doesn't allow to take a photo normally because it take too much time to focus (several seconds), and image stream makes photo blurry even in preview mode. – Horvath

try using the image_picker plugin, you can adjust the image quality and resolution easily.

void pickImage() async {
    var image = await ImagePicker().getImage(
      source: ImageSource.camera,
      preferredCameraDevice: CameraDevice.front,
      imageQuality: 100,
      maxWidth: 5000,
      maxHeight: 5000,
    );
    setState(() {
      _image = File(image.path);
      print(_image);
    });
  }

That won't work. I'm looking to show the camera feed in a widget. – Tilford
