Flutter 应用在​​ Release 模式下使用 Firestore 插件时崩溃

Question

在调试模式下，一切正常。它第一次发生在我将 Flutter 版本更新到 1.10.x 时，我不记得我正确使用了哪个版本。它应该是 1.7.8，它是稳定的。为了修复它，我将 flutter 降级到 1.7.8+4 并降级与 firebase 相关的 pub 包。但错误仍然在这里。

当我在设备上看到错误跟踪时（在 android 崩溃报告对话框中）它提到了 Firebase 19.0.0

颤振医生：

Doctor summary (to see all details, run flutter doctor -v):
[?] Flutter (Channel unknown, v1.7.8+hotfix.4, on Microsoft Windows [Version 10.0.17134.1069], locale en-US)

• No issues found!

最终描述的错误报告场景：

• 构建应用程序 flutter run --release
• 应用程序尝试基本的 Firestore 调用

  Firestore.instance.collection('collection-name').document('docuemnt-id').get()

• 应用程序崩溃。

构建时也遇到相同的错误 flutter build appbudle

这是我噩梦的解决方案。

要修复此错误，请android.enableR8=false更新gradle.properties. 您需要添加此行，因为默认值为true。

Answer 2

我有一个类似的案例（相同的错误），所以我会尝试告诉您发生了什么，也许与您遇到的问题相同。

就我而言，我丢失了密钥库，所以我经历了请求新密钥等的所有过程，之后我发布了一个新版本，并且我的应用程序以与您完全相同的方式崩溃，经过大量谷歌和其他内容我发现这与签名有关（因为在调试中有效，但在发布中不起作用），所以我进入 firebase 控制台并再次下载 google-services.json 文件，令人惊讶的是......该文件有一个以前不存在的块。

之后，我使用您在此处提供的命令在设备中进行测试（顺便说一句，谢谢！），哇啦！有用。

我还在控制台中更新了 SHA-1 签名密钥，因此这也可能有所帮助。希望我的回答能够帮助您找到解决方案。
