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)]
