Question

我是 flutter 的新手，我面临这个问题，即在清理构建（flutter clean）后，我的代码停止工作并且卡在构建失败中..

我尝试删除 Flutter SDK 并再次执行该过程，但仍然收到相同的错误消息。

我试图修复 Firebase 登录并替换了“google-services.json”文件，然后在执行这些命令后 [clean build、pub get 和 pub upgrade] 代码卡在构建中。

（这是错误信息和 screenshot）

我试图搜索这个构建失败的问题，但我无法修复它。

Answer 1

在您应用的 pubspec.yaml 文件中查找此行：flutter_widget_from_html 并使用版本 ^ 0.5.1 + 3

例如：flutter_widget_from_html：^0.5.1+3

然后点击 pub upgrade 并运行您的应用

Answer 2

“最简单的解决方法是运行 flutter pub upgrade 以确保同时更新 flutter_widget_from_html 和 flutter_widget_from_html_core。”

在升级 pub 之前，您应该将 pubspec.yaml 中的最新软件包版本限制为 flutter_widget_from_html: ^0.5.2
