将提供程序包添加到Flutter Web项目时出错 [英] Error when adding provider package to flutter web project

问题描述

我试图将提供程序包添加到我的flutter网站项目中，并收到以下错误：

I tried to add the provider package to my flutter web project and got the following error:

因为每个版本的提供程序都取决于从sdk中扑灭任何>禁止的，提供者被禁止。
因此，因为WebApplication依赖于提供程序^ 3.0.0，所以版本解析>失败。

Because every version of provider depends on flutter any from sdk which is >forbidden, provider is forbidden. So, because WebApplication depends on provider ^3.0.0, version solving >failed.

Flutter用户应运行 flutter软件包get 而不是 pub get 。
流程结束，退出代码为69

Flutter users should run flutter packages get instead of pub get. Process finished with exit code 69

我尝试了 flutter软件包获得，并将flutter升级到最新版本。
当运行 flutter软件包获取时，不会显示错误，但是当我尝试 webdev服务时，以下错误是显示：

I tried flutter packages get and also upgraded flutter to the newest version. When running flutter packages get the error is not shown but when i tried webdev serve the following error is shown:

webdev无法为此项目运行。
在> C：\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\provider-3.0.0中找不到名为 pubspec.yaml的文件。

webdev could not run for this project. Could not find a file named "pubspec.yaml" in >"C:\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\provider-3.0.0".

我也看了广告 https://github.com/flutter/flutter/issues/21338 但没有解决我的错误。

also i looked ad https://github.com/flutter/flutter/issues/21338 but didn't solve my error.

使用kevmoo的 https://github.com/kevmoo/provider的 flutter_web 分支 povider叉为：

Use flutter_web branch of kevmoo's https://github.com/kevmoo/provider povider fork as:

dependencies:
  flutter_web: any
  flutter_web_ui: any
  provider: any

dependency_overrides:
  flutter_web:
    git:
      url: https://github.com/flutter/flutter_web
      path: packages/flutter_web
  flutter_web_ui:
    git:
      url: https://github.com/flutter/flutter_web
      path: packages/flutter_web_ui
  provider:
    git:
      url: https://github.com/kevmoo/provider
      ref: flutter_web
