package_info 0.5.0-nullsafety

Flutter plugin for querying information about the application package, such as CFBundleVersion on iOS or versionCode on Android.

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.
