AccelerometerFeaturesProbe class

A probe collecting accelerometer data over a sampling period and calculates a set of features based on the samplings, as represented by a AccelerationFeatures data point.

Configured with a PeriodicSamplingConfiguration configuration.

Methods

addError(Object error, [StackTrace? stacktrace]) → void
Add error to the measurements stream.
inherited
addMeasurement(Measurement measurement) → void
Add measurement to the measurements stream.
inherited
arePermissionsGranted() → Future<bool>
Does this probe has the permissions needed to run?
inherited
dispose() → void
Dispose of this executor.
inherited
error() → void
inherited
getMeasurement() → Future<Measurement?>
Subclasses should implement / override this method to collect the Measurement. This method will be called every time data has been buffered for a duration and should return the final measurement for the buffered data.
override
initialize(Measure configuration, [SmartphoneDeployment? deployment]) → void
Configure and initialize the executor before using it.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onDispose() → Future<void>
Callback when this executor is disposed.
inherited
onInitialize() → bool
Callback when this executor is initialized. Returns true if successfully initialized, false otherwise.
inherited
onPause() → Future<bool>
Callback when this executor is paused. Returns true if successfully paused, false otherwise.
inherited
onResume() → Future<bool>
Callback when this executor is resumed. Returns true if successfully resumed, false otherwise.
inherited
onSamplingData(dynamic event) → void
Handler for handling onData events from the buffering stream.
override
onSamplingEnd() → void
Handler called when sampling period ends.
override
onSamplingStart() → void
Handler called when sampling period starts.
override
pause() → void
Pause the executor. Paused until resume is called.
inherited
pauseButShouldBeResumed() → void
Pause the executor but mark it to be resumed when possible.
inherited
requestPermissions() → Future<bool>
Request the permissions needed for this probe to run. Return true if all permissions are granted. Only used on Android - iOS automatically request permissions when a resource (like the microphone) is accessed.
inherited
resume() → void
Resume the executor.
inherited
toString() → String
A string representation of this object.

Operators

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