Using the FlutterAppDelegate

Letting your application’s UIApplicationDelegate subclass
FlutterAppDelegate is recommended but not required.

The FlutterAppDelegate performs functions such as:

Forwarding application callbacks such as openURL
to plugins such as local_auth.

Keeping the Flutter connection open 
in debug mode when the phone screen locks.
