Question

当我为通用设备构建或为实际设备运行时，在xcode上出现以下错误

ld: warning: Could not find auto-linked framework 'Flutter' Undefined symbols for architecture armv7:   "_FlutterMethodNotImplemented", referenced from:
      -[FLTDeviceInfoPlugin handleMethodCall:result:] in DeviceInfoPlugin.o   "_OBJC_CLASS_$_FlutterMethodChannel", referenced from:
      objc-class-ref in DeviceInfoPlugin.o ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

flutter build命令运行没有错误

颤抖的医生：

但是当我将频道更改为主频道时，不会出现错误。由于我想发布我的应用，因此我无法在Master频道上做到这一点！
