A Flutter plugin that allows you to check if an app is installed/enabled, launch an app and get the list of installed apps.
This plugin was inspired by the plugin ScrumlabAppAvailability for Cordova.
For help getting started with Flutter, view our online documentation.
For help on editing plugin code, view the documentation.
First, add scrumlab_flutter_appavailability
as a dependency in your pubspec.yaml file.
checkAvailability(String uri)
getInstalledApps()
(only for Android)isAppEnabled(String uri)
(only for Android)launchApp(String uri)
See the docs.
Here is a small example flutter app displaying a list of installed apps that you can launch.
import 'package:flutter/material.dart';
import 'dart:async';
import 'dart:io';
import 'package:scrumlab_flutter_appavailability/scrumlab_flutter_appavailability.dart';
void main() => runApp(new MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => new _MyAppState();
}
class _MyAppState extends State<MyApp> {
List<Map<String, String>> installedApps;
List<Map<String, String>> iOSApps = [
{
"app_name": "Calendar",
"package_name": "calshow://"
},
{
"app_name": "Facebook",
"package_name": "fb://"
},
{
"app_name": "Whatsapp",
"package_name": "whatsapp://"
}
];
@override
void initState() {
super.initState();
}
// Platform messages are asynchronous, so we initialize in an async method.
Future<void> getApps() async {
List<Map<String, String>> _installedApps;
if (Platform.isAndroid) {
_installedApps = await ScrumlabAppAvailability.getInstalledApps();
print(await ScrumlabAppAvailability.checkAvailability("com.android.chrome"));
// Returns: Map<String, String>{app_name: Chrome, package_name: com.android.chrome, versionCode: null, version_name: 55.0.2883.91}
print(await ScrumlabAppAvailability.isAppEnabled("com.android.chrome"));
// Returns: true
}
else if (Platform.isIOS) {
// iOS doesn't allow to get installed apps.
_installedApps = iOSApps;
print(await ScrumlabAppAvailability.checkAvailability("calshow://"));
// Returns: Map<String, String>{app_name: , package_name: calshow://, versionCode: , version_name: }
}
setState(() {
installedApps = _installedApps;
});
}
@override
Widget build(BuildContext context) {
if (installedApps == null)
getApps();
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin scrumlab_flutter_appavailability app'),
),
body: ListView.builder(
itemCount: installedApps == null ? 0 : installedApps.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(installedApps[index]["app_name"]),
trailing: IconButton(
icon: const Icon(Icons.open_in_new),
onPressed: () {
Scaffold.of(context).hideCurrentSnackBar();
ScrumlabAppAvailability.launchApp(installedApps[index]["package_name"]).then((_) {
print("App ${installedApps[index]["app_name"]} launched!");
}).catchError((err) {
Scaffold.of(context).showSnackBar(SnackBar(
content: Text("App ${installedApps[index]["app_name"]} not found!")
));
print(err);
});
}
),
);
},
),
