Flutter学习笔记--用原生工程打包时报错的解决办法

在原生的iOS工程里面，嵌套了flutter模块，进行打包时，报以下错误：
ld: bitcode bundle could not be generated because ‘/Users/—/ios/Flutter/Flutter.framework/Flutter’ was built without full bitcode. All frameworks and dylibs for bitcode must be generated from Xcode Archive or Install build file ‘/Users/—r/ios/Flutter/Flutter.framework/Flutter’ for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation) Search for Enable Bitcode setting and set it to YES for Debug and Release modes.

从报错信息来看，该报错信息是因为flutter模块里面的内容不是全部支持bitcode导致的，但我将项目里面的Enable Bitcode设置为NO时，并没有解决问题：

最后在Stack Overflow上面找到了答案，正确操作是：不需要将Enable Bitcode设置为NO，在flutter项目里面，依次执行以下命令：
flutter clean
flutter build ios

然后再在原生工程里面做正常的打包操作，成功！！
