如何在flatter中启动URL？

注意：关于这个问题，我已经搜索了很多年了&阅读了StackOverflow上所有类似的问题

我正在制作颤振应用程序，我想在点击按钮时启动一个URL（基于画布）

一切都很好，直到我使用“url_启动器”

我使用的是颤振1.13.6（最新版本）

下面是我正在使用的重定向函数

import 'package:url_launcher/url_launcher.dart' as URLLaucher;

abstract class URL {
  static launchURL(String url) async {
    url = Uri.encodeFull(url);
    if (await URLLaucher.canLaunch(url)) {
      await URLLaucher.launch(url);
    } else {
      throw 'Unknown error, can\'t launch the URL. Холбоост нэвтрэхэд алдаа гарлаа';
    }
  }
}

这是我运行“颤振运行”命令时得到的错误日志

当您在pubspec.yaml中添加了某些内容后进行热重启时，就会发生这种情况-只需关闭应用程序并再次安装即可

我也遇到了同样的错误。

因此，我将颤振升级到

v1.12.13

，并使用

url\u launcher5.3.0

，它成功了。

您能尝试访问吗？您似乎无法下载等级文件。您的url_启动器版本和颤振版本~sdk:“>=2.3.0在这里是相同的，不管怎样
