invalid reuse after initialization failure

用android studio运行没问题

xcode release 版本 使用flutter run --release运行
关键点：flutter 编译配置要显式指定 release。

flutter clean
flutter build ios

# 然后 XCode 打开项目，找到 Flutter/Generated.xcconfig 文件
# 在文件最后加上
FLUTTER_BUILD_MODE=release

# 然后 archive
# 最后导出时，选择 Development 而不是 App Store，否则只能选 dis 证书而不能选 dev 证书

open -a Simulator 命令打开模拟器
