Flutter: how to insert a link in a RichText widget

Question

In this video they say you can use a Gesture recognizers in order to create a clickable link in your TextSpan, but I found no examples in the RichText official documentation and in general on internet. Can someone please explain me how to do that?

Answer 1

Basically is something like this

RichText(
  text: TextSpan(
    children: [
      TextSpan(text: 'Hello'),
        TextSpan(
          text: 'World',
            recognizer: TapGestureRecognizer()
              ..onTap = () async {
                //Code to launch your URL
              }
        )
      ]
   )
);

You can use the URL launcher to manage the links, that goes like this:

const url = 'https://flutter.dev';
if (await canLaunch(url)) {
    await launch(url);
} else {
    throw 'Could not launch $url';
}
