Firestore：脱机时事务崩溃 [英] Firestore: Transactions crashing when offline

问题描述

我知道根据变更日志（0.12.9 + 5）。据推测，它修复了Android设备上的崩溃问题，该问题导致在离线状态下尝试 Transaction 会导致应用程序崩溃。但是，即使使用0.13.7（我正在使用的版本）。我仍然遇到应用崩溃的问题。控制台中没有错误日志（只是立即崩溃）。

I am aware that according to the changelog (0.12.9+5). It supposedly fixed a crash on android where Transactions attempted while offline would result in an app crash. However, even with 0.13.7 (the version I'm using). I'm still running into app crashes. There is no error log in the console (just immediate crash).

我已经尝试过：

1. 运行我的物理设备上处于调试模式的应用程序（行为相同）


2. 附加错误句柄回调（未调用）


3. 降低我的 cloud_firestore 版本降至0.12.11（在查询中支持 whereIn 的最低版本；这是我需要的，并且高于0.12.9 + 5）

1. Running my app in debug mode on a physical device (same behavior)
2. Attaching error handle callback (not called)
3. Lowering my cloud_firestore version down to 0.12.11 (the lowest version that supported whereIn in querying; it is something I needed and above 0.12.9+5)
