take precedence over framework defaults.
getter/setter pairinherited

Fling velocity magnitudes will be clamped to this value.
getter/setter pairinherited
-
minFlingDistance
↔ double?
-
The minimum distance an input pointer drag must have moved
to be considered a fling gesture.
getter/setter pairinherited
-
minFlingVelocity
↔ double?
-
The minimum velocity for an input pointer drag to be considered fling.
getter/setter pairinherited
-
multitouchDragStrategy
↔ MultitouchDragStrategy

Configure the multi-finger drag strategy on multi-touch devices.
getter/setter pairinherited
-
onCancel
↔ GestureDragCancelCallback?
-
The pointer that previously triggered onDown did not complete.
getter/setter pairinherited
-
onDown
↔ GestureDragDownCallback?
-
A pointer has contacted the screen with a primary button and might begin
to move.
getter/setter pairinherited
-
onEnd
↔ GestureDragEndCallback?
-
A pointer that was previously in contact with the screen with a primary
button and moving is no longer in contact with the screen and was moving
at a specific velocity when it stopped contacting the screen.
getter/setter pairinherited
-
onlyAcceptDragOnThreshold
↔ bool
-
Whether the drag threshold should be met before dispatching any drag callbacks.
getter/setter pairinherited
-
onStart
↔ GestureDragStartCallback?
-
A pointer has contacted the screen with a primary button and has begun to
move.
getter/setter pairinherited
-
onUpdate
↔ GestureDragUpdateCallback?
-
A pointer that is in contact with the screen with a primary button and
moving has moved again.
getter/setter pairinherited
-
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
-
velocityTrackerBuilder
↔ GestureVelocityTrackerBuilder
-
Determines the type of velocity estimation method to use for a potential
drag gesture, when a new pointer is added.
getter/setter pairinherited
