Using Package Info Plus

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()


PackageInfo packageInfo = await PackageInfo.fromPlatform();

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

Known Issues


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.

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

As noted on issue 20761, package_info 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.

Plugin returns package version in buildNumber when no build number specified in pubspec.yaml

Plugin doesn't modify the output of iOS. In this case buildNumber in the plugin is CFBundleVersion in iOS. This property returns version when build number is not specified.buildNumber See CFBundleVersion docs for more inf.

Android (and potentially all platforms)

Calling to PackageInfo.fromPlatform() before the runApp() call will cause an exception. See
