MissingPluginException(No implementation found for method check on channel plugins.flutter.io/connectivity

I'm using this connectivity plugin to check the internet connectivity status. It works fine with the flutter dart code but when I called the flutter dart code from native android kotlin code this missingplugin exception occurs. So for me this error occurs only when the flutter code is called from native android kotlin code using platform channel.

Also, The GeneratedPluginRegistrant.java file is called from mainactivity.kt file but in the file there is no registerwith code for connectivity and many other plugins. I don't understand why it is not generated automatically?

  }
}

Any suggestions would be really helpful. Thanks in advance.
