Flutter应用包信息获取插件package_info_plus_tizen的使用

package_info_plus_tizen 是 package_info_plus 在 Tizen 平台上的实现。

使用

此插件不是 package_info_plus 的官方实现。因此，你需要在 pubspec.yaml 文件中同时包含 package_info_plus 和 package_info_plus_tizen 作为依赖项。

dependencies:
  package_info_plus: ^8.0.0
  package_info_plus_tizen: ^1.0.4

然后你可以在 Dart 代码中导入 package_info_plus：

import 'package:package_info_plus/package_info_plus.dart';

对于更详细的用法，请参阅 https://pub.dev/packages/package_info_plus#usage。

支持的属性

• ✅ PackageInfo.appName
• ✅ PackageInfo.packageName
• ✅ PackageInfo.version
• ❌ PackageInfo.buildNumber
• ❌ PackageInfo.buildSignature
• ❌ PackageInfo.installerStore
