A light sensor plugin for Flutter, reads the intensity of light in lux, and reports this number back. The API for getting the current light exposure is only available on Android devices, and the plugin will therefore not work for iOS devices.
Add light
as a dependency in pubspec.yaml
.
For help on adding as a dependency, view the documentation.
Al incoming data points are streamed with a StreamSubscription
which is set up by calling the listen()
method on a Light
object.
Given a method _onData(int lux)
the subscription can be set up as follows:
Light _light = new Light();
_light.listen(_onData);
The stream can also be cancelled again by calling the cancel()
method:
_light.cancel();
example/README.md
A Flutter plugin for retrieving the light sensor data using a platform channel. Works for Android only, since the light sensor API is not available on iOS.
class MyClass {
String _luxString = 'Unknown';
StreamSubscription<int> _subscription;
Light _light;
// Platform messages are asynchronous, so we initialize in an async method.
void someSetupFunction() {
_light = new Light();
_subscription = _light.lightSensorStream.listen(_onData,
onError: _onError, onDone: _onDone, cancelOnError: true);
}
void _onData(int luxValue) async {
// Do something with the luxValue
}
void _onDone() {
// Handle finish
}
void _onError(error) {
// Handle the error
}
}
Add this to your package's pubspec.yaml file:
dependencies:
light: ^0.0.6
You can install packages from the command line:
with Flutter:
$ flutter packages get
Alternatively, your editor might support flutter packages get
.
Check the docs for your editor to learn more.
Now in your Dart code, you can use:
import 'package:light/light.dart';
