我在颤振中错误地使用了flutter_sim_country_code软件包

Question

当我运行我的颤振项目或运行pub get命令时，我得到了这个错误。我研究了我的颤振项目中的代码，我没有使用这个插件，但是我找不到flutter_sim_country_code插件的用法。下面提到了错误。

The plugin `flutter_sim_country_code` doesn't have a main class defined in E:\flutter_windows_2.0.2-stable\flutter\.pub-cache\hosted\pub.dartlang.org\flutter_sim_country_code-0.1.1\android\src\main\java\com\example\flutter_sim_country_code\FlutterSimCountryCodePlugin.java or E:\flutter_windows_2.0.2-stable\flutter\.pub-cache\hosted\pub.dartlang.org\flutter_sim_country_code-0.1.1\android\src\main\kotlin\com\example\flutter_sim_country_code\FlutterSimCountryCodePlugin.kt. This is likely to due to an incorrect `androidPackage: com.example.flutter_sim_country_code` or `mainClass` entry in the plugin's pubspec.yaml.
    If you are the author of this plugin, fix the `androidPackage` entry or move the main class to any of locations used above. Otherwise, please contact the author of this plugin and consider using a different plugin in the meanwhile.

Answer 1

在我的例子中，我对包名"androidPackage: com.example.flutter_sim_country_code"有异议，这与我的实际包名"androidPackage: com.myappbuilder.flutter_sim_country_code"不匹配。所以这不是工作。

如果有人面临同样的问题，那么您必须在您的项目中首先检查您的包名。

好像是插件的问题。相反，我建议你使用替代插件。

使用这

String carrierInfo = await CarrierInfo.isoCountryCode;  // The ISO country code for the user’s cellular service provider.
