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';

PackageInfo packageInfo = await PackageInfo.fromPlatform();

String appName = packageInfo.appName;

String packageName = packageInfo.packageName;

String version = packageInfo.version;

String buildNumber = packageInfo.buildNumber;

Or in async mode:

PackageInfo.fromPlatform().then((PackageInfo packageInfo) {

String appName = packageInfo.appName;

String packageName = packageInfo.packageName;

String version = packageInfo.version;

String buildNumber = packageInfo.buildNumber;

});

Known Issue

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.
