Link Detector From String (Custom Widget)

Widget which detects and hyperlinks URL's from a string. I've used this within social media platforms I've created to automatically detect URL's from user posts.

Example: Here is a link to google: https://google.com -> here is a link to google: https://google.com/

import 'package:flutter_linkify/flutter_linkify.dart';
import 'package:url_launcher/url_launcher.dart';

class Flutterlinkify extends StatefulWidget {
  const Flutterlinkify(
      {Key? key, this.width, this.height, this.text, this.fontSize, required this.color})
      : super(key: key);

  final double? width;
  final double? height;
  final String? text;
  final double? fontSize;
  final Color color;

  @override
  _FlutterlinkifyState createState() => _FlutterlinkifyState();
}

class _FlutterlinkifyState extends State<Flutterlinkify> {
  @override
  Widget build(BuildContext context) {
    return Container(
        child: SelectableLinkify(
      onOpen: (link) async {
        if (await canLaunch(link.url)) {
          await launch(link.url);
        } else {
          throw 'Could not launch $link';
        }
      },
      text: widget.text!,
      style: TextStyle(
          color: widget.color,
        	fontSize: widget.fontSize),
      linkStyle: TextStyle(
          fontWeight: FontWeight.bold,
          color: widget.color,
          fontSize: widget.fontSize),
    ));
  }
}
