2 days ago Hi @kanojiyasmit,
There are several issues with your code that are preventing it from operating as you expect. This is not a problem with the package itself. I recommend posting to a forum that provides help with Flutter and Dart coding.

}Hi @faithoflifedev ,
Thank you for the correction. I tried this approach, but I’m still encountering the same error on the iOS side.

Hi @faithoflifedev , The application fails to send UDP packets due to a “No route to host” error during device discovery.
