As canLaunch and launch methods are deprecated in url_launcher. Now you can use canLaunchUrl instead of canLaunch and launchUrl instead of launch i.e.

var url = "https://www.facebook.com/minorijapaneserestaurant"; 
if(await canLaunchUrl(Uri.parse(url))) { 
  await launchUrl(Uri.parse(url)); 
} else { 
  throw "Cannot load Url $url";
}

Welcome to SO.

Do as the message says, replace canLaunch(url) with canLaunchUrl(url).
