在Flutter web应用程序中运行flutter build web时，我遇到了一系列无法找到解决方案的错误。
这是一个Flutter网络应用程序。我没有使用Android或iOS或其他任何东西。截至上周五(2022年8月12日(，该建筑状况良好。
在终端中运行flutter build web时，我得到以下错误：
Target dart2js failed: Exception: Warning: The 'dart2js' entrypoint script is deprecated, please use 'dart compile js' instead.

这些错误让我认为JavaScript是如何生成的，和/或是否在没有零安全的情况下构建存在问题。
Flutter修复程序今天合并了Flutter/issues/109160，旨在修复generated_plugin_registrant.dart的一个问题，但它被降级到主通道和测试通道。我在稳定频道。

在repo中的每个文件的顶部，我都有// @dart=2.9，这样在我被迁移之前，构建不应该使用空安全性。
我试过：
flutter pub get->flutter clean->flutter build webflutter pub upgrade->flutter pub outdated->flutter pub upgrade --major-versions->flutter clean->flutter build web --no-sound-null-safety
我读过&尝试使用：
- flutter/issues/109160，但这似乎不相关，因为我在稳定通道上
- S。O.getting-error-target-dart2js
- 无法编译我的flutter网页
- flutter build web构建没有健全的零安全并在错误时运行
我还创建了一个test_web_app，导入了Firebase/FlutterFire库，构建得很好，尽管无可否认，我实际上并没有在测试应用程序中使用它们中的任何一个。我只是将它们添加到pubspec和index.html中，看看这是否对构建有任何影响。
感谢您的指导&想想看！！！
我通过以下操作解决了构建问题：
- 运行

手动将
pubspec.yaml更新为"；最新的"；为cloud_firestore、firebase_core、firebase_auth和cloud_functions中的每一个列出的版本。VS Code自动为我运行
flutter pub get。flutter build web测试
；"玛丽万岁"；，但它起了作用。我不明白为什么一周内会出现问题，但如果有人有任何见解，我很想了解他们！！！
