camera_extended is a fork of Flutter's official camera plugin that adds native aspect-ratio support (16:9, 4:3, 1:1). Instead of cropping a frame after capture, it configures the camera at the native sensor level through CameraX on Android and AVFoundation on iOS — so a 1:1 request yields a genuinely wider field of view rather than a centre crop of a 4:3 or 16:9 frame.

• Native aspect-ratio selection — 16:9, 4:3 and 1:1 configured at the sensor level, not a post-capture crop
• Native 1:1 square on Android (e.g. 1088×1088, 720×720); falls back to 4:3 on iOS
• Wider field of view with 4:3 or 1:1 instead of a centre crop of a 16:9 frame
• Drop-in replacement — the full official camera API plus the aspect-ratio additions
• takePictureAsBytes() returns a Uint8List directly, skipping file I/O for ML pipelines and uploads
• Per-device video stabilization via getSupportedVideoStabilizationModes() and setVideoStabilizationMode()

camera_extended is API-compatible with the official camera package — the same CameraController, CameraPreview, capture and video methods behave identically. It replaces camera in your dependencies; the only additions are the optional aspectRatio constructor parameter, the targetAspectRatio getter, takePictureAsBytes(), the video-stabilization methods and the CameraAspectRatio enum. Migrating is a dependency swap plus an import change.

# 1. Swap the dependency in pubspec.yaml
# -  camera: ^0.11.0
# +  camera_extended: ^1.2.4

// 2. Update the import
import 'package:camera_extended/camera_extended.dart';

// 3. Optionally request an aspect ratio
CameraController(
  camera,
  ResolutionPreset.high,
  aspectRatio: CameraAspectRatio.ratio4x3,
);

Add the dependency to your pubspec.yaml in place of camera:

dependencies:
  camera_extended: ^1.2.4

Or add it from the command line:

flutter pub add camera_extended

Enumerate the cameras with availableCameras(), create a CameraController with the aspect ratio you want, call initialize(), then render CameraPreview and capture with takePicture().

import 'package:camera_extended/camera_extended.dart';

late List<CameraDescription> cameras;

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  cameras = await availableCameras();
  runApp(const MyApp());
}

// Create a controller with a native aspect ratio.
final controller = CameraController(
  cameras.first,
  ResolutionPreset.high,
  enableAudio: false,
  aspectRatio: CameraAspectRatio.ratio4x3, // sensor-level ratio
);

await controller.initialize();

// Show the live preview: CameraPreview(controller)
// Capture a still image:
final XFile photo = await controller.takePicture();

camera_extended is a federated plugin. You depend on the single camera_extended package; it pulls in three published siblings that provide the platform interface and the native implementations.
