[iPad]camera preview is cropped when compared with native camera

[seidoragutierrez]

Hello,

I am programming an app for iOS and Android in Flutter that must use the camera to automatically capture images every second. I have to create a screen in portarit orientation that shows the preview of what I want to photograph and that preview must fit the width of the screen. However, I am unable to get it to work correctly on iOS as the CameraPreview doesn't display all the visual information that it should. On Android, however, everything looks fine. Below I attach two images that show the problem. On the left is the image that I get in flutter on iOS, while on the right is the one that should appear.

I have done the tests in an iPad mini 4.

Thanks

Steps to Reproduce

1. Execute flutter run on the code sample on iPad mini

Actual results (left) vs Expected result (right)

Code sample

```dart import 'package:camera/camera.dart'; import 'package:flutter/material.dart'; List cameras = []; Future main() async { // Fetch the available cameras before initializing the app. try { WidgetsFlutterBinding.ensureInitialized(); cameras = await availableCameras(); } on CameraException catch (e) { print('Error in fetching the cameras: $e'); } runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', theme: ThemeData( primarySwatch: Colors.blue, ), debugShowCheckedModeBanner: false, home: TakePictureScreenG( camera: cameras.first, ), ); } } class TakePictureScreenG extends StatefulWidget { const TakePictureScreenG({Key? key, required this.camera}) : super(key: key); final CameraDescription camera; @override TakePictureScreenGState createState() => TakePictureScreenGState(); } class TakePictureScreenGState extends State { late CameraController _controller; late Future _initializeControllerFuture; final num resWPreset = 2160; final num resHPreset = 3840; final ResolutionPreset resolutionPreset = ResolutionPreset.ultraHigh; @override void initState() { super.initState(); _controller = CameraController(widget.camera, resolutionPreset); _initializeControllerFuture = _controller.initialize(); } @override void dispose() { _controller.dispose(); super.dispose(); } @override Widget build(BuildContext context) { return Scaffold( body: Stack(children: [ _buildCamera(), ]), ); } Widget _buildCamera() { return FutureBuilder( future: _initializeControllerFuture, builder: (context, snapshot) { if (snapshot.connectionState != ConnectionState.done) { return Center( child: Column( mainAxisAlignment: MainAxisAlignment.spaceAround, children: [ Spacer(), Text("LOADING CAMERA"), CircularProgressIndicator(), Spacer() ], ), ); } var sizeWScreen = MediaQuery.of(context).size.width; return Container( width: sizeWScreen, height: resHPreset * sizeWScreen / resWPreset, child: CameraPreview(_controller), ); }, ); } } ```
