Usage

You can use the PackageInfo to query information about the application package. This works both on iOS and Android.

import 'package:package_info_plus/package_info_plus.dart';

...

// Be sure to add this line if `PackageInfo.fromPlatform()` is called before runApp()
WidgetsFlutterBinding.ensureInitialized();

...

PackageInfo packageInfo = await PackageInfo.fromPlatform();

String appName = packageInfo.appName;
String packageName = packageInfo.packageName;
String version = packageInfo.version;
String buildNumber = packageInfo.buildNumber;

Known Issues

iOS

Plugin returns incorrect app version

Flutter build tools allow only digits and . (dot) symbols to be used in version of pubspec.yaml on iOS/MacOS to comply with official version format from Apple.

More info available in this comment

I have changed version in pubspec.yaml and plugin returns wrong info

As noted on issue 20761, package_info_plus on iOS requires the Xcode build folder to be rebuilt after changes to the version string in pubspec.yaml. Clean the Xcode build folder with: XCode Menu -> Product -> (Holding Option Key) Clean build folder.

Android (and potentially all platforms)

Calling to PackageInfo.fromPlatform() before the runApp() call will cause an exception. See fluttercommunity/plus_plugins#309

Windows

I see wrong version on Windows platform

There was an issue in Flutter, which is already resolved since Flutter 3.3. If your project was created before Flutter 3.3 you need to migrate the project according to [this guide] (https://docs.flutter.dev/release/breaking-changes/windows-version-information) first to get correct version with package_info_plus
