When I added flutter_camera_ml_vision to an existing project, I got the following error.
Execution failed for task ':app:checkDebugAarMetadata'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
> Could not find com.google.firebase:firebase-ml-vision:.
Required by:
project :app > project :firebase_ml_vision
I didn't know what caused it, so I copied the code (from the official website). After that, I tried to link firebase and added only flutter_camera_ml_vision, but I got the same error as above.
The main.dart is the same as the URL above, and the other files that I changed are as follows. The version of flutter_camera_ml_vision is 3.0.1. As a supplement, the ./gradlew command succeeds.

I got similar when using firebase_ml_vision: ^0.12.0+2
,
then I downgrade to firebase_ml_vision: ^0.9.10
and added following in app/build.gradle
:
implementation platform('com.google.firebase:firebase-bom:28.0.1') implementation 'com.google.android.gms:play-services-vision:20.1.3'
then app can be compiled.
