Usage #
Add sensors_plus
as a dependency in your pubspec.yaml file.
This will expose such classes of sensor events through a set of streams:
AccelerometerEvent
describes the velocity of the device, including the effects of gravity. Put simply, you can use accelerometer readings to tell if the device is moving in a particular direction.UserAccelerometerEvent
also describes the velocity of the device, but don't include gravity. They can also be thought of as just the user's affect on the device.GyroscopeEvent
describes the rotation of the device.MagnetometerEvent
describes the ambient magnetic field surrounding the device. A compass is an example usage of this data.
These events are exposed through a BroadcastStream
: accelerometerEvents
,
userAccelerometerEvents
, gyroscopeEvents
, and magnetometerEvents
,
respectively.
Example #
import 'package:sensors_plus/sensors_plus.dart';
accelerometerEvents.listen((AccelerometerEvent event) {
print(event);
});
// [AccelerometerEvent (x: 0.0, y: 9.8, z: 0.0)]
userAccelerometerEvents.listen((UserAccelerometerEvent event) {
print(event);
});
// [UserAccelerometerEvent (x: 0.0, y: 0.0, z: 0.0)]
gyroscopeEvents.listen((GyroscopeEvent event) {
print(event);
});
// [GyroscopeEvent (x: 0.0, y: 0.0, z: 0.0)]
magnetometerEvents.listen((MagnetometerEvent event) {
print(event);
});
// [MagnetometerEvent (x: -23.6, y: 6.2, z: -34.9)]

subdirectory for an example application that uses the
sensor data.
