I'm trying to use Firebase RemoteConfig in my Flutter Web App, but when I call the method "fetchAndActivate", a strange error occurs:
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
RemoteConfig.instance.fetchAndActivate();
Error:
Error: Expected a value of type 'int', but got one of type 'Null'

Update: New version with Remote Config support on the web was released.
At this time, Remote config is not supported on Flutter Web. Link.
