TapDownEvent class

The event propagated through the Flame engine when the user starts a touch on the game canvas.

This is a PositionEvent, where the position is the point of touch.

In order for a component to be eligible to receive this event, it must add the TapCallbacks mixin.

Constructors

canvasPosition → Vector2: Event position in the coordinate space of the game widget, i.e. relative to the game canvas.
latefinalinherited
continuePropagation ↔ bool: If this flag is false (default), the event will be delivered to the first component that can handle it. If that component sets this flag to true, the event will propagate further down the component tree to other eligible components.

deviceKind → PointerDeviceKind: final
devicePosition → Vector2: Event position in the coordinate space of the device -- either the phone, or the browser window, or the app.
finalinherited
handled ↔ bool: Flag that can be used to indicate that the event was handled by one of the components.
getter/setter pairinherited
hashCode → int: The hash code for this object.
no setterinherited
localPosition → Vector2: Event position in the local coordinate space of the current component.
no setterinherited
parentContext → Vector2?: The context in the parent's coordinate space, containing start and end points.
no setterinherited
pointerId → int: The unique identifier of the tap event.
final
renderingTrace → List<Vector2>: The stacktrace of coordinates of the event within the components in their rendering order.
finalinherited
runtimeType → Type: A representation of the runtime type of the object.
