Compile error on "Using the device camera (p.510)"

[stefvenmans]

Hi!

I am trying to get the device camera example from the cookbook running but get the following compile error. I used the main.dart, camera.dart, picture.dart and pubspec.yaml file provided here without changing anything.

This is the error stack I am getting:

Running "flutter pub get" in camera_app...
The plugin firebase_mlkit_language uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.
