After Alice update i am getting those errors on application start-up. Thought app is running just fine, i can't access Alice (no push-notification, shake gesture doesn't bring up Alice UI).

Unhandled Exception: ServicesBinding.defaultBinaryMessenger was accessed before the binding was initialized.
If you're running an application and need to access the binary messenger before `runApp()` has been called (for example, during plugin initialization), then you need to explicitly call the `WidgetsFlutterBinding.ensureInitialized()` first.
If you're running a test, you can call the `TestWidgetsFlutterBinding.ensureInitialized()` as the first line in your test's `main()` method to initialize the binding.

Can you share your example? Especially class with main.

Also try call WidgetsFlutterBinding.ensureInitialized() before init Alice.
