sensors 0.4.2+6

Flutter Android iOS

Flutter plugin for accessing the Android and iOS accelerometer and gyroscope sensors.

sensors #

Please set your constraint to sensors: '>=0.4.y+x <2.0.0'

Backward compatible 1.0.0 version is coming #

The sensors plugin has reached a stable API, we guarantee that version 1.0.0 will be backward compatible with 0.4.y+z. Please use sensors: '>=0.4.y+x <2.0.0' as your dependency constraint to allow a smoother ecosystem migration. For more details see: https://github.com/flutter/flutter/wiki/Package-migration-to-1.0.0

A Flutter plugin to access the accelerometer and gyroscope sensors.

Usage #

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.

  • AccelerometerEvents 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.
  • UserAccelerometerEvents 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.
  • GyroscopeEvents describe the rotation of the device.

Each of these is exposed through a BroadcastStream: accelerometerEvents, userAccelerometerEvents, and gyroscopeEvents, respectively.

Example #

import 'package:sensors/sensors.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)]

Also see the example subdirectory for an example application that uses the sensor data.
