YOLOViewController class
Controls a YOLOView imperatively: thresholds, camera, zoom, streaming.
Constructors
Properties
- confidenceThreshold → double
-
no setter
-
focusEvents
→ Stream<
Offset> -
Emits the normalized (0..1) view-relative tap-to-focus point.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- iouThreshold → double
-
no setter
- isInitialized → bool
-
no setter
- isTorchEnabled → bool
-
Whether the torch (flashlight) is currently enabled, per the last setTorchMode/toggleTorch call.
no setter
-
lensEvents
→ Stream<
String> -
Emits the label of the currently selected lens whenever it changes.
no setter
- numItemsThreshold → int
-
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- showOverlays → bool
-
Whether native prediction overlays are shown, per the last setShowOverlays call.
no setter
-
zoomEvents
→ Stream<
double> -
Emits the native zoom factor whenever it changes (e.g. via pinch).
no setter
Methods
-
captureFrame(
) → Future< Uint8List?> -
capturePhoto(
{bool withOverlays = true}) → Future< Uint8List?> - Captures a still photo from the live preview.
-
dispose(
) → void - Releases the broadcast stream controllers owned by this controller.
-
getAvailableLenses(
) → Future< List< LensInfo> > - Returns the lenses the active device exposes (back camera lens cluster).
-
init(
MethodChannel methodChannel, int viewId) → void -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onNativeEvent(
Map event) → void -
Routes a typed native event (
zoom/lens/focus) to the matching stream. -
pause(
) → Future< void> - Pause the preview. On iOS this snapshots the next frame into the native share-image cache before stopping the session (so capturePhoto after pause returns the frozen frame); on Android it unbinds the camera use-cases while keeping the predictor alive.
-
resetTorchState(
) → void - Resets the cached torch state to off without a platform call. Use after an operation where the platform drops the torch on its own (e.g. switching the camera input), so isTorchEnabled stays in sync.
-
restartCamera(
) → Future< void> -
resume(
) → Future< void> -
Resume after pause. iOS clears the cached share frame and restarts the session; Android aliases to
restartCamera(). -
setConfidenceThreshold(
double threshold) → Future< void> -
setIoUThreshold(
double threshold) → Future< void> -
setLens(
double zoomFactor) → Future< void> -
Snaps the active camera to the lens whose native zoom factor is
zoomFactor. -
setNumItemsThreshold(
int numItems) → Future< void> -
setShowOverlays(
bool visible) → Future< void> - Shows or hides native prediction overlays without changing inference callbacks.
-
setStreamingConfig(
YOLOStreamingConfig config) → Future< void> -
setThresholds(
{double? confidenceThreshold, double? iouThreshold, int? numItemsThreshold}) → Future< void> -
setTorchMode(
bool enabled) → Future< void> - Turns the active camera's torch (flashlight) on or off. The platform returns the actual resulting torch state, which is cached in isTorchEnabled — so the cache stays correct even when the call fails or the active camera has no torch (e.g. most front cameras). On a swallowed platform error the cached state is left unchanged.
-
setZoomLevel(
double zoomLevel) → Future< void> -
stop(
) → Future< void> -
switchCamera(
) → Future< void> -
switchModel(
String modelPath, [YOLOTask? task]) → Future< void> -
tapToFocus(
double x, double y) → Future< void> -
Requests focus + exposure at the view-relative point (
x,yin 0..1). -
toggleTorch(
) → Future< void> - Toggles the torch (flashlight) between on and off. See setTorchMode and isTorchEnabled.
-
toString(
) → String -
A string representation of this object.

zoomIn(
) → Future< void> -
zoomOut(
) → Future< void>
Operators
-
operator ==(
Object other) → bool -
The equality operator.
