添加了flutter模块后，iOS打包出错 Bitcode bu

问题：

项目是iOS原生和Flutter混编的，今天打包出现了如下错误：

Bitcode bundle could not be generated because 
'/Users/yuhua/Library/Developer/Xcode/DerivedData/SmarterLifeV4-
czvdwotaihmeahgulpjtacuurjpl/Build/Intermediates.noindex/ArchiveInter
mediates/SmarterLifeV4/BuildProductsPath/Release-
iphoneos/XCFrameworkIntermediates/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/yuhua/Library/Developer/Xcode/DerivedData/SmarterLifeV4-
czvdwotaihmeahgulpjtacuurjpl/Build/Intermediates.noindex/ArchiveInter
mediates/SmarterLifeV4/BuildProductsPath/Release-
iphoneos/XCFrameworkIntermediates/Flutter/Flutter.framework/Flutter'
 for architecture armv7

解决问题

首先分析问题，字面描述就是Flutter.framework不包含完整的bitcode。重点是bitcode。解决步骤如下：

• 1.先去flutter项目中，找到iOS项目目录，打开，将项目的bitcode关闭。
• 2.然后再flutter项目中使用如下命令

flutter build ios

这一步大概率会需要设置iOS项目的包名和证书，设置好即可。

• 3.回到iOS项目中，打包。好了，问题解决。
