Simple sensor event listener plugin for flutter(Android & iOS).


First add the plugin in your project. Copy the following line below dependencies in your pubspec.yaml file.

    flutter_sensors: ^1.0.1

Then you need to import the dependency.

import 'package:flutter_sensors/flutter_sensors.dart';

iOS configuration

You need to add the following key-value pair into your Info.plist file inside the ios/Runner folder in your project.

<string>A reason to get the permission</string>

Android configuration

You need to add the following permission in your AndroidManifest.xml to use the step counter.

<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION"/>

How to use

You register a new listener for an specific sensor.

final stream = await SensorManager().sensorUpdates(
        sensorId: Sensors.ACCELEROMETER,
        interval: Sensors.SENSOR_DELAY_GAME,
_accelSubscription = stream.listen((sensorEvent) {
        setState(() {
          _accelData = sensorEvent.data;

Also, you can check if an specific sensor is available.

bool accelerometerAvailable =
        await SensorManager().isSensorAvailable(Sensors.ACCELEROMETER);

Remember to cancel your StreamSubscriptions after you are done with the sensor updates.


Android Only

You can give the ID of a sensor without using the Sensors class. Example: registering a listener for the TYPE_LIGHT sensor.

int TYPE_LIGHT = 5; // TYPE_LIGHT is equals to 5
// Checking if is available.
bool isAvailable = await SensorManager().isSensorAvailable(TYPE_LIGHT);
// Initialize a stream to receive the updates.
final stream = await SensorManager().sensorUpdates(sensorId: TYPE_LIGHT);
_lightSubscription = stream.listen((sensorEvent) {
        setState(() {
          _lightData = sensorEvent.data;
 // Cancel the stream after using it.

You can get the rest of the IDs from here.
