如何获取Flutter Web应用程序的内部版本和版本号 [英] How to get build and version number of Flutter Web app

问题描述

此处的关键字是网络.我可以使用 package_info 插件来获取Flutter应用程序的内部版本号和版本号.在网络上无法运行.如何获取Flutter Web应用程序的软件包信息?

The keyword here is Web. I can get the build and version number of a Flutter app by using the package_info plugin, but if it is running on the web I can't. How do I get the package info for a Flutter Web app?

我将在下面提供一个答案作为临时解决方案，但我正在寻找一个从pubspec.yaml获取版本信息的解决方案.

I'll include an answer below as a temporary fix, but I am looking a solution that gets the version info from pubspec.yaml.

推荐答案

作为临时的解决方法，您可以创建一个单独的文件，其中包含版本信息:

As a temporary workaround you can create a separate file with the version info in it:

web_version_info.dart

class WebVersionInfo {
  static const String name = '1.0.0';
  static const int build = 1;
}

您可以将其用于所有平台，也可以在代码中使用kIsWeb仅将其用于网络:

You can use that for all platforms or in your code you can use kIsWeb to just use it for the web:

Future<String> _getAppVersion() async {
  if (kIsWeb) {
    return WebVersionInfo.name;
  } else {
    PackageInfo packageInfo = await PackageInfo.fromPlatform();
    return packageInfo.version;
  }
}

当然，这不是一个很好的解决方案，因为现在您每次更新应用程序时都需要记住要更新版本并在pubspec.yaml和WebVersionInfo中构建信息.

Of course, this is not a great solution because now you need to remember to update the version and build information in both pubspec.yaml and in WebVersionInfo every time you update the app.
