AndroidMotionEvent class Null safety

A Dart version of Android's MotionEvent.

This is used by AndroidViewController to describe pointer events that are forwarded to a platform view when Flutter receives an event that it determines is to be handled by that platform view rather than by another Flutter widget.

Properties

action int
A value representing the kind of action being performed. [...]
final
buttonState int
The state of all buttons that are pressed such as a mouse or stylus button. [...]
final
deviceId int
See Android's MotionEvent#getDeviceId.
final
downTime int
The time (in ms) when the user originally pressed down to start a stream of position events, relative to an arbitrary timeline. [...]
final
edgeFlags int
A bit field indicating which edges, if any, were touched by this MotionEvent. [...]
final
eventTime int
The time this event occurred, relative to an arbitrary timeline. [...]
final
flags int
See Android's MotionEvent#getFlags.
final
hashCode int
The hash code for this object. [...]
read-only, inherited
metaState int
The state of any meta / modifier keys that were in effect when the event was generated. [...]
final
motionEventId int
Used to identify this MotionEvent uniquely in the Flutter Engine.
final
pointerCoords List<AndroidPointerCoords>
List of AndroidPointerCoords for each pointer that is part of this event.
final
pointerCount int
The number of pointers that are part of this event. This must be equivalent to the length of pointerProperties and pointerCoords. [...]
final
pointerProperties List<AndroidPointerProperties>
List of AndroidPointerProperties for each pointer that is part of this event.
final
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
source int
The source of this event (e.g a touchpad or stylus). [...]
final
xPrecision double
The precision of the X coordinates being reported, in physical pixels. [...]
final
yPrecision double
The precision of the Y coordinates being reported, in physical pixels. [...]
final

Methods
