TBLWebViewGestureRecognizer class

Inheritance

Constructors

TBLWebViewGestureRecognizer(TBLWebView TBLWebView, BuildContext buildContext)

Properties

allowedButtonsFilter → AllowedButtonsFilter
Called when interaction starts. This limits the dragging behavior for custom clicks (such as scroll click). Its parameter comes from PointerEvent.buttons.
finalinherited
canWVContentScrollUp ↔ bool
getter/setter pair
debugDescription → String
Returns a very short pretty description of the gesture that the recognizer looks for, like 'tap' or 'horizontal drag'.
no setteroverride
debugOwner → Object?
The recognizer's owner.
finalinherited
didReceiveFromMLScrollToTop ↔ bool
getter/setter pair
dragDistance ↔ Offset
getter/setter pair
gestureSettings ↔ DeviceGestureSettings?
Optional device specific configuration for device gestures that will take precedence over framework defaults.
getter/setter pairinherited
hashCode → int
The hash code for this object.
no setterinherited
mDeltaX ↔ double
getter/setter pair
mDeltaY ↔ double
getter/setter pair
mOldPointX ↔ double
getter/setter pair
mOldPointY ↔ double
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
supportedDevices ↔ Set<PointerDeviceKind>?
The kind of devices that are allowed to be recognized as provided by supportedDevices in the constructor, or the currently deprecated kind. These cannot both be set. If both are null, events from all device kinds will be tracked and recognized.
getter/setter pairinherited
team ↔ GestureArenaTeam?
The team that this recognizer belongs to, if any.
getter/setter pairinherited
yGlobal ↔ double
getter/setter pair

Methods

acceptGesture(int pointer) → void
Called when this member wins the arena for the given pointer id.
inherited
addAllowedPointer(PointerDownEvent event) → void
Registers a new pointer that's been checked to be allowed by this gesture recognizer.
inherited
addAllowedPointerPanZoom(PointerPanZoomStartEvent event) → void
Registers a new pointer pan/zoom that's been checked to be allowed by this gesture recognizer.
inherited
addPointer(PointerEvent event) → void
This is the only event that we managed to switch scrolling to web content
override
addPointerPanZoom(PointerPanZoomStartEvent event) → void
Registers a new pointer pan/zoom that might be relevant to this gesture detector.
inherited
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
didStopTrackingLastPointer(int pointer) → void
Called when the number of pointers this recognizer is tracking changes from one to zero.
override
dispose() → void
Releases any resources used by the object.
inherited
getKindForPointer(int pointer) → PointerDeviceKind
For a given pointer ID, returns the device kind associated with it.
inherited
getScrollingDirection(double touchMovementDeltaY) → int
handleEvent(PointerEvent event) → void
Called when a pointer event is routed to this recognizer.
override
handleNonAllowedPointer(PointerDownEvent event) → void
Handles a pointer being added that's not allowed by this recognizer.
inherited
handleNonAllowedPointerPanZoom(PointerPanZoomStartEvent event) → void
Handles a pointer pan/zoom being added that's not allowed by this recognizer.
inherited
invokeCallback<T>(String name, RecognizerCallback<T> callback, {String debugReport()?}) → T?
Invoke a callback provided by the application, catching and logging any exceptions.
inherited
isHorizontalScrolling(double mDeltaX, double mDeltaY) → bool
Previously, we were determining if mDeltaX > mDeltaY to identify horizontal scroll, but this approach was flawed. It misclassified diagonal scrolls, such as those at 45 degrees, as horizontal scrolls.
isPointerAllowed(PointerDownEvent event) → bool
Checks whether or not a pointer is allowed to be tracked by this recognizer.
inherited
isPointerPanZoomAllowed(PointerPanZoomStartEvent event) → bool
Checks whether or not a pointer pan/zoom is allowed to be tracked by this recognizer.
inherited
isWebViewAtScreenTop() → bool
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onWebViewScrolledToContentTop() → void
This event is eventually called from MobileLoader, when the WebView's content reached top
rejectGesture(int pointer) → void
Called when this member loses the arena for the given pointer id.
inherited
resolve(GestureDisposition disposition) → void
Resolves this recognizer's participation in each gesture arena with the given disposition.
inherited
resolvePointer(int pointer, GestureDisposition disposition) → void
Resolves this recognizer's participation in the given gesture arena with the given disposition.
inherited
startTrackingPointer(int pointer, [Matrix4? transform]) → void
Causes events related to the given pointer ID to be routed to this recognizer.
inherited
stopTrackingIfPointerNoLongerDown(PointerEvent event) → void
Stops tracking the pointer associated with the given event if the event is a PointerUpEvent or a PointerCancelEvent event.
inherited
stopTrackingPointer(int pointer) → void
Stops events related to the given pointer ID from being routed to this recognizer.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.

Operators

operator ==(Object other) → bool
The equality operator.
