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.
_accelSubscription.cancel();

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.
_lightSubscription.cancel();
