向应用程序添加 Web 支持时出现 Flutter 错误

Question

我刚刚发现我可以将我的flutter应用程序更改为一个网站而无需编写外部代码。我决定在我的应用程序上对其进行测试，但出现此错误并且我不知道如何修复它。我按照 "website" 上的步骤操作，但仍然出现错误。我的堆栈跟踪是：-

This application is not configured to build on the web.
To add web support to a project, run `flutter create .`.
Launching lib\main.dart on Web Server in debug mode...
Syncing files to device Web Server...
org-dartlang-app:/web_entrypoint.dart:8:8: Error: Error when reading 'lib/generated_plugin_registrant.dart': The system cannot find the file specified.

import 'package:discountapp/generated_plugin_registrant.dart';
       ^
org-dartlang-app:/web_entrypoint.dart:11:3: Error: Method not found: 'registerPlugins'.
  registerPlugins(webPluginRegistry);
  ^^^^^^^^^^^^^^^
Failed to compile application.

我运行扑创建。它说

运行扑运行会运行它在我的 phone 上。我将提供所需的任何代码。请帮忙

Answer 1

您必须运行 flutter create . 在应用程序的根文件夹中，但不能在 ios 子文件夹中。

Answer 2

将 ios 文件夹重命名为 _ios
运行在您的终端中执行此命令：flutter create --platforms=web .
将 _ios 文件夹重新命名为 ios

这会将所有需要的文件写入运行您在浏览器上的应用程序。
