Use get_version package . It's the easiest way
Installing :
dependencies:
get_version: any
Usage:
String projectAppID;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
projectAppID = await GetVersion.appID;
} on PlatformException {
projectAppID = 'Failed to get app ID.';
}
You can use it as String inside anything you want like Text widget etc ...
Another extract of get_version in a small application :
import 'package:get_version/get_version.dart';
class _MyAppState extends State<MyApp> {
String _projectAppID = '';
@override
initState() {
super.initState();
initPlatformState();
}
// Platform messages are asynchronous, so we initialize in an async method.
initPlatformState() async {
String projectAppID;
try {
projectAppID = await GetVersion.appID;
} catch (e) {
projectAppID = 'Failed to get app ID.';
}
setState(() {
_projectAppID = projectAppID;
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: ListTile(
leading: new Icon(Icons.info),
title: const Text('App ID'),
subtitle: new Text(_projectAppID),
),
),
);
}
}
Output :
