PointerMoveEvent class

The pointer has moved with respect to the device while the pointer is in contact with the device.

See also:

  • PointerHoverEvent, which reports movement while the pointer is not in contact with the device.

PointerMoveEvent({Duration timeStamp: Duration.zero, int pointer: 0, PointerDeviceKind kind: PointerDeviceKind.touch, int device: 0, Offset position: Offset.zero, Offset delta: Offset.zero, 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, bool synthesized: false })
Creates a pointer move 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
The 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 → Offset
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
synthesized → bool
We occasionally synthesize PointerEvents that aren't exact translations of ui.PointerData from the engine to cover small cross-OS discrepancies in pointer behaviors. [...]
final, 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

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.
inherited

Operators

operator ==(dynamic other) → bool
The equality operator. [...]
