Answer 1

I tested as follows and it worked. Please give it a try.

Don't worry if you see a warning in this section that a deprecated feature is being used.

_launchURL(url) async {
  if (await canLaunch(url)) {
    await launch(url);
  } else {
    throw 'Could not launch $url';
  }
}




IconButton(
    onPressed: () async {
      await launchUrl(Uri.parse("https://t.me/jobcontainer"));
    },
    icon: const Icon(
      Icons.telegram,
      color: Colors.blue,
    ),
    iconSize: 45,
  ),
