MultiTaskYOLOView class
A Flutter widget that runs detect, classify, and optionally segment simultaneously on a single camera stream — no JPEG round-trip, no MethodChannel per frame.
Pass segmentModelPath to enable a third segmentation model running in parallel.
The onStreamingData callback fires for every result; check data["type"]
("detect", "classify", or "segment") to route results.

Properties
- classifyConfidenceThreshold → double?
-
final
- classifyModelPath → String
-
final
- confidenceThreshold → double
-
Default confidence threshold, applied to any task without a per-model override.
final
- controller → MultiTaskYOLOController?
-
final
- detectConfidenceThreshold → double?
-
Per-model overrides. When null, the corresponding model falls back to the
global confidenceThreshold / iouThreshold. Classification only uses a
confidence threshold (IoU does not apply to it).
final
- detectIouThreshold → double?
-
final
- detectModelPath → String
-
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- iouThreshold → double
-
Default IoU (NMS) threshold, applied to any task without a per-model override.
final
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- lensFacing → String
-
final
- onStreamingData → MultiTaskStreamCallback?
-
final
- runtimeType → Type
-
A representation of the runtime type of the object.

- segmentConfidenceThreshold → double?
-
final
- segmentIouThreshold → double?
-
final
- segmentModelPath → String?
-
Optional segmentation model. When non-null, runs in parallel with detect + classify.
Results arrive via onStreamingData with
data["type"] == "segment".final - useGpu → bool
