PackageInfo #

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

Please set your constraint to package_info: '>=0.4.y+x <2.0.0'

Backward compatible 1.0.0 version is coming #

The package_info plugin has reached a stable API, we guarantee that version 1.0.0 will be backward compatible with 0.4.y+z. Please use package_info: '>=0.4.y+x <2.0.0' as your dependency constraint to allow a smoother ecosystem migration. For more details see: https://github.com/flutter/flutter/wiki/Package-migration-to-1.0.0

Usage #

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 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.
