MultiTaskYOLOView class

A Flutter widget that runs two detection models plus a classification model simultaneously on a single camera stream — no JPEG round-trip, no MethodChannel per frame. Each model runs concurrently on its own queue.

Pass secondDetectModelPath to enable a second detection model running in parallel with the primary detect + classify models. The onStreamingData callback fires for every result; route on data["modelId"] ("detect", "detect2", "classify") since both detection models report data["type"] == "detect".

Constructors

MultiTaskYOLOView({Key? key, required String detectModelPath, required String classifyModelPath, required String? secondDetectModelPath, MultiTaskYOLOController? controller, MultiTaskStreamCallback? onStreamingData, String lensFacing = 'back', bool useGpu = true, double confidenceThreshold = 0.25, double iouThreshold = 0.7, double? detectConfidenceThreshold, double? detectIouThreshold, double? classifyConfidenceThreshold, double? secondDetectConfidenceThreshold, double? secondDetectIouThreshold})

Properties

classifyConfidenceThreshold → double?
final
classifyModelPath → String
final
confidenceThreshold → double
Default confidence threshold, applied to any model 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
Primary detection model. Results arrive with data["modelId"] == "detect".
final
hashCode → int
The hash code for this object.
no setterinherited
iouThreshold → double
Default IoU (NMS) threshold, applied to any model 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.
no setterinherited
secondDetectConfidenceThreshold → double?
final
secondDetectIouThreshold → double?
final
secondDetectModelPath → String?
Second detection model. When non-null, runs in parallel with the primary detect + classify models; pass null to run only detect + classify. Results arrive via onStreamingData with data["type"] == "detect" and data["modelId"] == "detect2".
final
useGpu → bool
