体系结构i386的未定义符号：_FlutterMethodNotImplemented

Question

我正在尝试在ios模拟器上运行我的flutter应用程序，该模拟器具有一些插件，例如连通性，flutter_webview，fluttertoast等。当我尝试运行这些插件时，所有这些插件都出现了以下错误。

Undefined symbols for architecture i386:
  "_FlutterMethodNotImplemented", referenced from:
      -[FluttertoastPlugin handleMethodCall:result:] in FluttertoastPlugin.o
  "_OBJC_CLASS_$_FlutterMethodChannel", referenced from:
      objc-class-ref in FluttertoastPlugin.o

事情在android上运行顺利。

我试过了

flutter clean 
pod install

错误仍然存​​在。任何人都面临类似的错误吗？如果有人对此有解决方案，请帮助我。谢谢

Answer 2

此错误与Undefined symbols for architecture i386
这对我有用 - 对于报告警告的目标，将“有效架构”设置更改为：

$(VALID_ARCHS)
x86_64

PS：如果这没有帮助，请转到“构建设置”并搜索“No Common Blocks”并将其设置为“No”。构建并运行。
