DetectedObject class

A single detected object with bounding box and category.

Mirrors MediaPipe's Detection class for the Object Detector solution.

Example:

final detections = await detector.detect(imageBytes);
for (final obj in detections) {
  final box = obj.boundingBox;
  final cat = obj.categories.first;
  print('Found ${cat.categoryName} (${(cat.score * 100).toStringAsFixed(1)}%) '
        'at (${box.topLeft.x.toInt()}, ${box.topLeft.y.toInt()})');
}

Constructors

DetectedObject({required Detection detection, required List<Category> categories, required Size originalSize})
Creates a detected object with the given detection, categories, and image size.
DetectedObject.fromMap(Map<String, dynamic> map)
Creates a DetectedObject from a serialized map.
