CameraController with ResolutionPreset.max causes Unsupported format Error

[noze12]

Steps to reproduce

1. create new flutter project
2. add camera dependency with flutter pub add camera
3. copy camera example code and paste it to main.dart
4. run on iOS device

Expected results

app starts and displays camera preview

Actual results

app crashs

in Xcode console

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AVCaptureDevice _setActiveFormat:resetVideoZoomFactorAndMinMaxFrameDurations:sessionPreset:] Unsupported format (<FLTDefaultCaptureDeviceFormat: 0x3024dd5e0>) - use -formats to discover valid formats'
...

When I change resolutionPreset to other value, it works correctly.

Code sample

Code sample

import 'package:camera/camera.dart';
import 'package:flutter/material.dart';

late List<CameraDescription> _cameras;

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  _cameras = await availableCameras();
  runApp(const CameraApp());
}

/// CameraApp is the Main Application.
class CameraApp extends StatefulWidget {
  /// Default Constructor
  const CameraApp({super.key});

  @override
  State<CameraApp> createState() => _CameraAppState();
}

class _CameraAppState extends State<CameraApp> {
  late CameraController controller;

  @override
  void initState() {
    super.initState();
    controller = CameraController(_cameras[0], ResolutionPreset.max);
    controller.initialize().then((_) {
      if (!mounted) {
        return;
      }
      setState(() {});
    }).catchError((Object e) {
      if (e is CameraException) {
        switch (e.code) {
          case 'CameraAccessDenied':
            // Handle access errors here.
            break;
          default:
            // Handle other errors here.
            break;
        }
      }
    });
  }

  @override
  void dispose() {
    controller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    if (!controller.value.isInitialized) {
      return Container();
    }
    return MaterialApp(
      home: CameraPreview(controller),
    );
  }
}

I can confirm it happens on an iPhone 15 (iOS 18.2) and iPhone SE 2022 (18.0) too:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AVCaptureDevice _setActiveFormat:resetVideoZoomFactorAndMinMaxFrameDurations:sessionPreset:] Unsupported format (<FLTDefaultCaptureDeviceFormat: 0x303ac57a0>) - use -formats to discover valid formats'

Switching the ResolutionPreset from max to ultraHigh seems to fix it.
It happened while I was upgrading from flutter 3.27.3 to 3.29.0, using camera package version 0.11.1.

Thanks for your report. I also can reproduce this issue on iPhone 7, iOS 15.8.3

I would like to add that specifying the fps is also crashing the app. I had it set to 30 and once I removed the line, it began to work normal, as long as the ResolutionPreset was not max

@noze12 which version of camera plugin are you using? if it's the latest version, can you try to revert to earlier version and see if it's a regression?
