flutter_android_lifecycle #

A new Flutter plugin to enable flutter developer get android activity lifecycle notifications from dart.

Getting Started #

currently, this package supports three lifecycle notifications:

- OnStart
- OnResume
- OnPause

To use this package, all you have to do is

  • add flutter_android_lifecycle to your pubspec.yaml
  • change your MainActivity.java or MainActivity.kt to extend FlutterAndroidLifecycleActivity
  • Then you can start listening on notification lifecycle with these codes inside initState of your flutter application

for OnStart

    FlutterAndroidLifecycle.listenToOnStartStream().listen((_) {
          print("ONSTART CALLED");
        });

for OnResume

    FlutterAndroidLifecycle.listenToOnResumeStream().listen((_) {
          print("ONRESUME CALLED");
        });

for OnPause

    FlutterAndroidLifecycle.listenToOnPauseStream().listen((_) {
          print("ONPAUSE CALLED");
        });

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

import 'package:flutter/services.dart';
import 'package:flutter_android_lifecycle/flutter_android_lifecycle.dart';

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

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

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';

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

    FlutterAndroidLifecycle.listenToOnStartStream().listen((_) {
      print("ONSTART CALLED");
    });

    FlutterAndroidLifecycle.listenToOnResumeStream().listen((_) {
      print("ONRESUME CALLED");
    });

    FlutterAndroidLifecycle.listenToOnPauseStream().listen((_) {
      print("ONPAUSE CALLED");
    });
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    String platformVersion;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      platformVersion = await FlutterAndroidLifecycle.platformVersion;
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: Text('Running on: $_platformVersion\n'),
        ),
      ),
    );
  }
