LongPressMoveUpdateEvent class

The event propagated through the Flame engine when the user moves their pointer during an active long press gesture.

This is a DisplacementEvent whose start/end positions represent a frame-to-frame delta, matching the semantics of DragUpdateEvent. Use localDelta to move a component to follow the pointer.

Constructors

LongPressMoveUpdateEvent(int pointerId, Game game, LongPressMoveUpdateDetails details, {required Offset previousGlobalPosition})
Creates a LongPressMoveUpdateEvent.

Properties

canvasDelta → Vector2
Event delta in the coordinate space of the game widget, i.e. relative to the game canvas.
latefinalinherited
canvasEndPosition → Vector2
Event end position in the coordinate space of the game widget, i.e. relative to the game canvas.
latefinalinherited
canvasStartPosition → Vector2
Event start 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.
getter/setter pairinherited
deviceDelta → Vector2
Event delta in the coordinate space of the device -- either the phone, or the browser window, or the app.
latefinalinherited
deviceEndPosition → Vector2
Event end position in the coordinate space of the device -- either the phone, or the browser window, or the app.
finalinherited
deviceStartPosition → Vector2
Event start 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.

final
parentContext → DisplacementContext?
The context in the parent's coordinate space, containing start and end points.
no setterinherited

The unique identifier for this long press gesture.
final
raw ↔ LongPressMoveUpdateDetails
