首先将此行添加到您的pubspec文件中:-url_launcher: ^5.4.2第二次使用此代码段:-

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

final Uri _emailLaunchUri = Uri(
 scheme: 'mailto',
 path: 'smith@example.com',
   queryParameters: {
    'subject': 'Example Subject & Symbols are allowed!'
   }
);
