Flutter：架构 arm64 的未定义符号

问题描述

迁移到 null-safety 和 Flutter 2 后，我的 ios 构建出现问题：
我跑 Flutter clean; rm ios/Podfile.lock pubspec.lock; rm -rf ios/Pods ios/Runner.xcworkspace; Flutter run --flavor dev -t lib/main_dev.dart

并得到这个 logcat：

我尝试过但没有帮助：

• pod deintegrate && rm Podfile.lock && pod install --repo-update
• 在 Podfile 中设置 platform :ios,'12.0'
• 在 Build Settings 中手动设置架构为 arm64

我在两个 Flutter 项目中遇到了这个问题，但我不知道如何解决。

更新： 看起来像是 Onesignal https://github.com/OneSignal/OneSignal-Flutter-SDK/issues/389

的问题

UPD2：
存在问题 https://github.com/rovkinmax/OneSignalSDKProblem

的示例项目

解决方法

我找到了解决此问题的方法：

1. 将所选配置设置为无

2. 检查复选框是否已打开
