Undefined symbols for architecture i386: _FlutterMethodNotImplemented : <p>I am trying to run my flutter app on ios simulator which has few plugins such as connectivity, flutter_webview, fluttertoast etc.
When I am trying to run these I am getting following error on all of these plugins.</p>

<pre><code>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
</code></pre>
