My function using image labeller.

Future<void> _labelScanner() async{
    result='';
    FirebaseVisionImage visionImage = FirebaseVisionImage.fromFile(_pickedImage);
    ImageLabeler labeler = FirebaseVision.instance.imageLabeler();
    final List<ImageLabel> labels = await labeler.processImage(visionImage);
    for(ImageLabel label in labels){
      print(label.toString());
    }
  }

Project level build.gradle file As mentioned in their official docs link. I have added the maven repository in both buildscript and dependency section.

buildscript {

            url 'https://maven.google.com/'
