迁移到 null-safety 和 flutter 2 后，我遇到了 ios build 问题：
我运行flutter clean; rm ios/Podfile.lock pubspec.lock; rm -rf ios/Pods ios/Runner.xcworkspace; flutter run --flavor dev -t lib/main_dev.dart

并得到了这个 logcat：

我尝试了什么并没有帮助：

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

我在两个颤振项目中遇到了这个问题，但我不知道如何解决它。

UPD：它看起来像 OneSignal 的问题https://github.com/OneSignal/OneSignal-Flutter-SDK/issues/389

我也遇到了这个问题并修复了

构建设置-> 搜索有效架构：

从列表中删除armv7

If Xcode version > 12.0 Then go project or target -> Build Settings -> Excluded Architecture

然后添加armv7
