This is likely to due to an incorrect `androidPackage: com.example.flutter_sim_country_code` or `mainClass` entry in the plugin's pubspec.yaml.

Getting this type of error when I run project.

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.
