- pubspec.yaml中依赖package_info_plus
package_info_plus: 4.0.2
-
执行下flutter pub get
-
获取所需应用信息
import 'package:package_info_plus/package_info_plus.dart';
...
// Be sure to add this line if `PackageInfo.fromPlatform()` is called before runApp()
WidgetsFlutterBinding.ensureInitialized();
...
PackageInfo packageInfo = await PackageInfo.fromPlatform();
String appName = packageInfo.appName;
String packageName = packageInfo.packageName;
String version = packageInfo.version;
String buildNumber = packageInfo.buildNumber;
以上按照插件文档所讲即可。
pubspec.yaml中:
version: 1.0.0+1
安卓获取的version对应的为pubspec.yaml中version中"+"号前面，buildNumber为version中"+"后面的。
这里主要说下iOS端获取原生端定义的Version和Build值:
新建flutter项目后，查看iOS原生端info.plist文件的定义，其中Bundle version string (short)的值为: (FLUTTER_BUILD_NUMBER)

而这时我们使用package_info_plus获取的version和buildNumber得到的值是flutter端pubspec.yaml中version的值，与安卓表现一致。
但是鉴于一个flutter项目，iOS与安卓版本号和build的值并不一定一致，对于iOS希望获取原生端定义的Version和Build，我们将info.plist中Bundle version string (short)和Bundle version的值修改为获取原生端的值即可。
Bundle version string (short): $(MARKETING_VERSION)
Bundle version: $(CURRENT_PROJECT_VERSION)

如此，iOS使用package_info_plus获取的version和buildNumber将是原生端定义的Version和Build
