More details here flutter/flutter#96405. The problem is that we are not using await for invokeMapMethod in the MethodChannelCamera.initializeCamera method:

final Completer<void> _completer = Completer<void>();
onCameraInitialized(cameraId).first.then((CameraInitializedEvent value) {
_completer.complete();
});
_channel.invokeMapMethod<String, dynamic>(
'initialize',
<String, dynamic>{
'cameraId': cameraId,
'imageFormatGroup': imageFormatGroup.name(),
},
);
return _completer.future;

The solution to is to asynchronously catch PlatformException and passing it to _completer.

Fix flutter/flutter#96405

If you had to change anything in the flutter/tests repo, include a link to the migration guide as per the breaking change policy.
