mailto：Flutter for Web的链接

2024-05-03 • 问答

url_launcher软件包（https://pub.dev/packages/url_launcher）似乎不适用于Flutter for Web。以下代码显示“ test url1”，但此后什么也没发生。

如何在Flutter for Web中实现类似mailto:的功能，该功能导致默认电子邮件应用程序打开并带有预填充的“收件人：”电子邮件地址？

flatButton(
  onpressed: _mailto,//() => {},padding: EdgeInsets.all(3.0),child: _contactBtn(viewportConstraints),)


  _mailto() async {
    const url = 'mailto:support@email.com?subject=Product Inquiry&body=';
    print("test url1");
    if (await canLaunch(url)) {
      print("test url2");
      await launch(url);
    } else {
      print("test url3");
      throw 'Could not launch $url';
    }
  }

import 'package:mailto/mailto.dart'; // For Flutter applications,you'll most likely want to use // the url_launcher package. import 'package:url_launcher/url_launcher.dart'; // ...somewhere in your Flutter app... launchMailto() async { final mailtoLink = Mailto( to: ['to@example.com'],cc: ['cc1@example.com','cc2@example.com'],subject: 'mailto example subject',body: 'mailto example body',); // Convert the Mailto instance into a string. // Use either Dart's string interpolation // or the toString() method. await launch('$mailtoLink'); }
