【中文标题】Flutter build 给出 .pub-cache cloud firestore 错误

【英文标题】：Flutter build gives a .pub-cache cloud firestore error

【发布时间】：2021-04-23 18:49:36

【问题描述】：

除了尝试使用 Cloud Firestore 运行 StreamBuilder 之外，我不记得有任何更改，然后开始出现以下错误。我评论了 Streambuilder，但没有任何变化。

**我已采取的步骤：

运行颤振 pub 缓存修复 跑扑干净 删除了 cloud firestore 包，然后调用 pub get，然后再次添加它并再次运行 pub get。**

包版本： firebase_core：^0.7.0 cloud_firestore: ^0.16.0

颤振： Flutter 1.22.5 • 通道稳定 • https://github.com/flutter/flutter.git 框架 • 修订 7891006299（6 周前） • 2020-12-10 11:54:40 -0800 引擎 • 修订版 ae90085a84 工具 • Dart 2.10.4

错误：

【问题讨论】：

你能告诉我们你的代码吗？您拨打StreamBuilder的地方。

添加了代码更新。 @Andrej

【参考方案1】：

这里https://github.com/Dart-Code/Dart-Code/issues/2172 提出的对我有用的解决方案是：

1.删除项目中的 .dart_tool 文件

2。转到 pubspec.yaml 并发布获取。
