iOS - Pickers not showing as part of module, but works when run as standalone.

[Jimmybee]

Describe the bug
Using FilePickerResult result = await FilePicker.platform.pickFiles(type: FileType.image); works fine when running as a straight forward Flutter project in the iOS simulator, showing both gallery picker and file picker.

Neither picker is appearing when using it as a flutter module in an iOS project.

    lazy var flutterEngine = FlutterEngine(name: "my flutter engine")

flutterEngine.run()
 GeneratedPluginRegistrant.register(with: self.flutterEngine)

Set FlutterViewController by:

window = UIWindow(frame: UIScreen.main.bounds)
window?.makeKeyAndVisible()
let flutterEngine = (UIApplication.shared.delegate as! AppDelegate).flutterEngine
let flutterViewController = FlutterViewController(engine: flutterEngine, nibName: nil, bundle: nil)
window?.rootViewController = flutterViewController

Hi, I might need help on this one as I don’t have a clue what might be causing it.

@Jimmybee this should be fixed with 2.1.4 thanks to #539. Let me know if it fixed for you and feel free to reopen this is you still experience any issue.

Thank you!
