This Flutter plugin provides an API for querying information about an application package.


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

import 'package:package_info/package_info.dart';

PackageInfo packageInfo = await PackageInfo.fromPlatform();

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

Or in async mode:

PackageInfo.fromPlatform().then((PackageInfo packageInfo) {
  String packageName = packageInfo.packageName;
  String version = packageInfo.version;
  String buildNumber = packageInfo.buildNumber;
