StreamProbe class abstract

An abstract class used to create a probe that listen continuously to events from the stream of Measurement objects.

Sub-classes must implement the

Stream<Measurement>? get stream => ...

method in order to provide the stream of measurements.

See BatteryProbe for an example.

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
initialize(Measure configuration, [SmartphoneDeployment? deployment]) → void
Configure and initialize the executor before starting 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
onRestart() → Future<bool>
Callback when this executor is to be restarted. Returns true if the executor is ready to restart (default), false otherwise.
override
onStart() → Future<bool>
Callback when this executor is started. Returns true if successfully started, false otherwise.
override
onStop() → Future<bool>
Callback when this executor is stopped. Returns true if successfully stopped, false otherwise.
override
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
restart() → void
Restart the executor.
inherited
start() → void
Start the executor.
inherited
stop() → void
Stop the executor. Stopped until start or restart is called.
inherited
toString() → String
A string representation of this object.

Operators

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