GravitySensor extension type

The GravitySensor interface of the Sensor APIs provides on each reading the gravity applied to the device along all three axes.

To use this sensor, the user must grant permission to the 'accelerometer' device sensor through the Permissions API. In addition, this feature may be blocked by a Permissions Policy set on your server.

Properties

activated → bool
The activated read-only property of the Sensor interface returns a boolean value indicating whether the sensor is active.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
hasReading → bool
The hasReading read-only property of the Sensor interface returns a boolean value indicating whether the sensor has a reading.

onreading ↔ EventHandler?
getter/setter pairinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
timestamp → double?
The timestamp read-only property of the Sensor interface returns the timestamp of the latest sensor reading.

Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
inherited
dispatchEvent(Event event) → bool
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeEventListener(String type, EventListener? callback, [JSAny options]) → void
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
start() → void
The start() method of the Sensor interface activates one of the sensors based on Sensor.
inherited
stop() → void
The stop() method of the Sensor interface deactivates the current sensor.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
