A Flutter plugin to access the accelerometer and gyroscope sensors.
To use this plugin, add sensors
as a dependency in your pubspec.yaml
file.
This will expose three classes of sensor events, through three different streams.
AccelerometerEvent
s describe 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
s also describe 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
s describe the rotation of the device.
Each of these is exposed through a BroadcastStream
: accelerometerEvents
,
userAccelerometerEvents
, and gyroscopeEvents
, respectively.
import 'package:sensors/sensors.dart';
accelerometerEvents.listen((AccelerometerEvent event) {
print(event);
});
// [AccelerometerEvent (x: 0.0, y: 9.8, z: 0.0)]
userAccelerometerEvents.listen((AccelerometerEvent 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)]

subdirectory for an example application that uses the
sensor data.
