When doing a hot restart on Android, it will freeze up due to an issue with Google Maps Flutter library:

I/flutter ( 4550): ----------------FIREBASE CRASHLYTICS----------------
I/flutter ( 4550): PlatformException(Renderer already initialized, Renderer initialization called multiple times, null, null)
I/flutter ( 4550): #0      MapsInitializerApi.initializeWithPreferredRenderer (package:google_maps_flutter_android/src/messages.g.dart:2945:7)
I/flutter ( 4550): <asynchronous suspension>
I/flutter ( 4550): #1      GoogleMapsFlutterAndroid.initializeWithRenderer (package:google_maps_flutter_android/src/google_maps_flutter_android.dart:494:9)
I/flutter ( 4550): <asynchronous suspension>
I/flutter ( 4550): #2      main.<anonymous closure> (package:campus_mobile_experimental/main.dart:36:7)
I/flutter ( 4550): <asynchronous suspension>

Also suspected to not work on iOS. The package can currently be upgraded without any breaking changes.
