getInstalledApps() (only for Android)
isAppEnabled(String uri) (only for Android)
launchApp(String uri)

Example #
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:flutter_appavailability/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 AppAvailability.getInstalledApps();

print(await AppAvailability.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 AppAvailability.isAppEnabled("com.android.chrome"));
// Returns: true

}
else if (Platform.isIOS) {
// iOS doesn't allow to get installed apps.
_installedApps = iOSApps;

print(await AppAvailability.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 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();
AppAvailability.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);
});
}
),
);
},
),
),
);
}
