screen_state #

pub package

A Flutter plugin for tracking the screen state.

Install #

Add screen_state as a dependency in pubspec.yaml. For help on adding as a dependency, view the documentation.

Usage #

All incoming data points are streamed with a StreamSubscription which is set up by calling the listen() method on the screenStateStream stream object.

Given a method _onData(ScreenStateEvent event) the subscription can be set up as follows:

Screen _screen;
StreamSubscription<ScreenStateEvent> _subscription;
...
void onData(ScreenStateEvent event) {
    print(event);
}

void startListening() {
    _screen = new Screen();
    try {
      _subscription = _screen.screenStateStream.listen(onData);
    } on ScreenStateException catch (exception) {
      print(exception);
    }
}

The stream can also be cancelled again by calling the cancel() method:

  void stopListening() {
    _subscription.cancel();
  }

example/lib/main.dart

import 'package:flutter/material.dart';
import 'dart:async';
import 'package:screen_state/screen_state.dart';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> {
  Screen _screen;
  StreamSubscription<ScreenStateEvent> _subscription;

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    startListening();
  }

  void onData(ScreenStateEvent event) {
    print(event);
  }

  void startListening() {
    _screen = new Screen();
    try {
      _subscription = _screen.screenStateStream.listen(onData);
    } on ScreenStateException catch (exception) {
      print(exception);
    }
  }

  void stopListening() {
    _subscription.cancel();
  }

  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: const Text('Screen State Example app'),
        ),
        body: new Center(),
      ),
    );
  }
