Static Methods

convertBoundingBox(Map boxMap) → Rect

Converts a {left, top, right, bottom} map to a Rect.

convertBoxesList(List boxes) → List<Map<String, dynamic>>

Alias of convertMapsList for detection-box lists.

convertKeypoints(List keypointsData) → ({List<double> confidences, List<Point> keypoints})

Unpacks a flat [x0, y0, c0, x1, y1, c1, ...] keypoint list into parallel lists of points and confidences.

convertMapsList(List maps) → List<Map<String, dynamic>>

Converts a list of dynamic maps to List<Map<String, dynamic>>, skipping non-map entries.

convertMaskData(List maskData) → List<List<double>>

Converts a list of rows of numbers into a typed List<List<double>> mask. Non-numeric values become 0.0.

convertToTypedMap(Map map) → Map<String, dynamic>

Converts a dynamic map to Map<String, dynamic>.

convertToTypedMapSafe(Map? map) → Map<String, dynamic>?

Null-safe variant of convertToTypedMap.

safeGetDouble(Map map, String key, {double fallback = 0.0}) → double

Reads map[key] as double; returns fallback if absent or non-numeric.

safeGetInt(Map map, String key, {int fallback = 0}) → int

Reads map[key] as int; returns fallback if absent or non-numeric.

safeGetString(Map map, String key, {String fallback = ''}) → String

Reads map[key] as String; returns fallback if absent or wrong type.

safeGetUint8List(Map map, String key) → Uint8List?

Reads map[key] as Uint8List or returns null.
