How to force update and not to let user to use app? #17
Description
Hi,
I need to force user to update app always. If they not going to update I should block user not to use app. Also I created a example app and try to use your example, but it didn't work and I guess there was no app that I am running in Google Play.
Later I update my app package name which is already in app store and I keep getting error as shown below.
I/flutter ( 7751): PlatformException(Failed to bind to the service., null, null)
Last, your example uses a button to check for update how to use this without button but in initState? Thanks
Note: I all need is to check for Update initial app initialization than force to make performImmediateUpdate().
My original app:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await SystemChrome.setEnabledSystemUIOverlays([]);
await SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);
runApp(new MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
SystemChrome.setEnabledSystemUIOverlays([]);
SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);
return new MaterialApp(
// TODO: SUPPORTED LOCALE
localizationsDelegates: [
const LangDelegate(),
GlobalMaterialLocalizations.delegate,
GlobalMaterialLocalizations.delegate,
GlobalMaterialLocalizations.delegate,
const FallbackCupertinoLocalisationsDelegate(),
],
supportedLocales: [
const Locale('tr', 'TR'),
const Locale('en', 'US'),
const Locale('ru', 'RU'),
],
debugShowCheckedModeBanner: false,
title: 'My Cep',
theme: new ThemeData(
primaryColor: capitalDarkGreen,
fontFamily: "Roboto",
),
home: new MyMainHomePage(),
);
}
}
And in MyMainHomePage I have PackageInfo and Connectivity in initState. So where I code the android app update?
Here is the full code (I am not sure where I am making mistake):
import 'package:flutter/material.dart';
import 'package:upgrader/upgrader.dart';
import 'dart:io' show Platform;
import 'dart:async';
import 'package:in_app_update/in_app_update.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
AppUpdateInfo _updateInfo;
GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey();
bool _flexibleUpdateAvailable = false;
@override
void initState() {
// TODO: implement initState
super.initState();
checkForUpdate();
//InAppUpdate.performImmediateUpdate().catchError((e) => _showError(e));
}
// Platform messages are asynchronous, so we initialize in an async method.
Future<void> checkForUpdate() async {
InAppUpdate.checkForUpdate().then((info) {
setState(() {
_updateInfo = info;
});
}).catchError((e) => _showError(e));
}
void _showError(dynamic exception) {
_scaffoldKey.currentState.showSnackBar(SnackBar(content: Text(exception.toString())));
print(exception.toString());
}
@override
Widget build(BuildContext context) {
return Scaffold(
key: _scaffoldKey,
appBar: AppBar(
title: const Text('In App Update Example App'),
),
body: _updateInfo?.updateAvailable == false
? new CircularProgressIndicator()
: Platform.isAndroid == true
? Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
children: <Widget>[
Center(
child: Text('Update info: $_updateInfo'),
),
RaisedButton(
child: Text('Check for Update'),
onPressed: () => checkForUpdate(),
),
RaisedButton(
child: Text('Perform immediate update'),
onPressed: _updateInfo?.updateAvailable == true
? () {
InAppUpdate.performImmediateUpdate().catchError((e) => _showError(e));
}
: null,
),
RaisedButton(
child: Text('Start flexible update'),
onPressed: _updateInfo?.updateAvailable == true
? () {
InAppUpdate.startFlexibleUpdate().then((_) {
setState(() {
_flexibleUpdateAvailable = true;
});
}).catchError((e) => _showError(e));
}
: null,
),
RaisedButton(
child: Text('Complete flexible update'),
onPressed: !_flexibleUpdateAvailable
? null
: () {
InAppUpdate.completeFlexibleUpdate().then((_) {
_scaffoldKey.currentState.showSnackBar(SnackBar(content: Text('Success!')));
}).catchError((e) => _showError(e));
},
)
],
),
)
: UpgradeAlert(
child: Center(child: Text('Checking...')),
));
}
}
