ImageLabeler class

Used for finding ImageLabels in a supplied image.

When you use the API, you get a list of the entities that were recognized: people, things, places, activities, and so on. Each label found comes with a score that indicates the confidence the ML model has in its relevance. With this information, you can perform tasks such as automatic metadata generation and content moderation.

A image labeler is created via imageLabeler([ImageLabelerOptions options]) or cloudImageLabeler([CloudImageLabelerOptions options]) in FirebaseVision:

final FirebaseVisionImage image =
    FirebaseVisionImage.fromFilePath('path/to/file');

final ImageLabeler imageLabeler =
    FirebaseVision.instance.imageLabeler(options);

final List<ImageLabel> labels = await imageLabeler.processImage(image);
