PointerDownEvent({Duration timeStamp: Duration.ZERO, int pointer: 0, PointerDeviceKind kind: PointerDeviceKind.touch, int device: 0, Point position: Point.origin, int buttons: 0, bool obscured: false, double pressure: 1.0, double pressureMin: 1.0, double pressureMax: 1.0, double distanceMax: 0.0, double radiusMajor: 0.0, double radiusMinor: 0.0, double radiusMin: 0.0, double radiusMax: 0.0, double orientation: 0.0, double tilt: 0.0 })

Creates a pointer down event.

Properties

buttons int

Bit field using the *Button constants (primaryMouseButton, secondaryStylusButton, etc). For example, if this has the value 6 and the kind is PointerDeviceKind.invertedStylus, then this indicates an upside-down stylus with both its primary and secondary buttons pressed.

final, inherited
delta Offset

Distance in logical pixels that the pointer moved since the last PointerMoveEvent. Always 0.0 for down, up, and cancel events.

final, inherited
device int

Unique identifier for the pointing device, reused across interactions.

final, inherited
distance double

The distance of the detected object from the input surface (e.g. the distance of a stylus or finger from a touch screen), in arbitrary units on an arbitrary (not necessarily linear) scale. If the pointer is down, this is 0.0 by definition.

final, inherited
distanceMax double

The maximum value that a distance can return for this pointer. If this input device cannot detect "hover touch" input events, then this will be 0.0.

final, inherited
distanceMin double

The minimum value that a distance can return for this pointer (always 0.0).

final, inherited
down bool

Set if the pointer is currently down. For touch and stylus pointers, this means the object (finger, pen) is in contact with the input surface. For mice, it means a button is pressed.

final, inherited
hashCode int

Get a hash code for this object.

read-only, inherited
kind PointerDeviceKind

The kind of input device for which the event was generated.

final, inherited
obscured bool

Set if an application from a different security domain is in any way obscuring this application's window. (Aspirational; not currently implemented.)

final, inherited
orientation double

For PointerDeviceKind.touch events:

final, inherited
pointer int

Unique identifier for the pointer, not reused.

final, inherited
position Point

Coordinate of the position of the pointer, in logical pixels in the global coordinate space.

final, inherited
pressure double

The pressure of the touch as a number ranging from 0.0, indicating a touch with no discernible pressure, to 1.0, indicating a touch with "normal" pressure, and possibly beyond, indicating a stronger touch. For devices that do not detect pressure (e.g. mice), returns 1.0.

final, inherited
pressureMax double

The maximum value that pressure can return for this pointer. For devices that do not detect pressure (e.g. mice), returns 1.0. This will always be a greater than or equal to 1.0.

final, inherited
pressureMin double

The minimum value that pressure can return for this pointer. For devices that do not detect pressure (e.g. mice), returns 1.0. This will always be a number less than or equal to 1.0.

final, inherited
radiusMajor double

The radius of the contact ellipse along the major axis, in logical pixels.

final, inherited
radiusMax double

The minimum value that could be reported for radiusMajor and radiusMinor for this pointer, in logical pixels.

final, inherited
radiusMin double

The minimum value that could be reported for radiusMajor and radiusMinor for this pointer, in logical pixels.

final, inherited
radiusMinor double

The radius of the contact ellipse along the minor axis, in logical pixels.

final, inherited
runtimeType Type

A representation of the runtime type of the object.

read-only, inherited
tilt double

For PointerDeviceKind.stylus and PointerDeviceKind.invertedStylus events:

final, inherited
timeStamp Duration

Time of event dispatch, relative to an arbitrary timeline.

final, inherited

Operators

operator ==(other) bool

The equality operator.

inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a non-existent method or property is accessed.

inherited
toString() String

Returns a string representation of this object.

inherited
toStringFull() String

Returns a complete textual description of this event.
