I want to create a hyperlink in Icon:

IconButton(

  onPressed: ()=>launch('https://github.com/himanshusharma89'),
)

How can we achieve this?

Error:

Exception has occurred.

Answer 1

Here is the solution, thanks to: Pavel

IconButton(
 icon: Icon(Icons.ac_unit,),
 onPressed: () async {
  const url = 'https://github.com/himanshusharma89';
  if (await canLaunch(url)) {
   await launch(url);
  } else {
   throw 'Could not launch $url';
  }
 }
)

The problem is that you have added dependency in pubspec.yaml and then just hot-reloaded the app. Native dependencies aren't added during hot reload. MissingPluginException means exactly that native (Android/iOS) plugin implementation is missed.

You should fully stop and start the app again
