【中文标题】架构 i386 的未定义符号：_FlutterMethodNotImplemented【英文标题】：Undefined symbols for architecture i386: _FlutterMethodNotImplemented 【发布时间】：2019-04-27 19:53:53 【问题描述】：

我正在尝试在 ios 模拟器上运行我的颤振应用程序，该模拟器具有很少的插件，例如连接、flutter_webview、fluttertoast 等。当我尝试运行这些插件时，所有这些插件都出现以下错误。

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

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？如果有人对此有解决方案，请帮助我。谢谢
