MissingPluginException while using plugin for flutter

I am trying to use the plugin

_launchURL(url) async {
  await launch("www.google.com");
}

I have put "www.google.com" just for debugging purposes.

The error I get is MissingPluginException :

restarting the app from ide doesn't work.

If you are using hot restart or hot reload, it won't do the trick. Since Flutter has to inject plugin dependencies into the platform-specific parts of your app, hot restart/hot reload is not enough to trigger the injection. Check this issue for more.

Close the app and execute flutter run command.

flutter clean

Inside the console did the job as stated here
