Unhandled exception error after adding AppDelegate.swift code to the app

[pgyusz]

After adding the AppDelegate.swift code (4. step) the app gives me this error
[VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: MissingPluginException(No implementation found for method getUDID on channel flutter_udid) #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:308:7) <asynchronous suspension> #1 FlutterUdid.udid (package:flutter_udid/flutter_udid.dart:15:25) <asynchronous suspension>

I thought that it was a package issue with flutter_udid, but after removing it I had problem with flutter_webview package and so on
Even after running pod update and pod install it still didn't fix it. I even regenerated the iOS folder, from zero, created a new flutter project but I still get the same issue.

If I leave the original AppDelegate.swift code, then the share extent stops after I select the app (my app).

Try restarting your environment.

• Cancel your current flutter run
• Restart your emulator (if used/running)
• Execute flutter clean and flutter pub get

this should solve your problem. Its a typical hot reloading issue.

Tried it, it does not fix anything.

After creating a new flutter project and importing only the flutter_share_intent package I get (kinda) the same exception

[VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: MissingPluginException(No implementation found for method getInitialSharing on channel flutter_sharing_intent)
#0      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:308:7)

======== Exception caught by services library ======================================================
The following MissingPluginException was thrown while activating platform stream on channel flutter_sharing_intent/events-sharing:
MissingPluginException(No implementation found for method listen on channel flutter_sharing_intent/events-sharing)

When the exception was thrown, this was the stack: 
#0      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:308:7)
<asynchronous suspension>
#1      EventChannel.receiveBroadcastStream.<anonymous closure> (package:flutter/src/services/platform_channel.dart:652:9)
<asynchronous suspension>
====================================================================================================

The exception only shows up when you add the example code to the main.dart.

I have the same issue. Were you able to fix it?

Edit:
Fixed it. The reason I saw this was because I replaced the existing application() function by the one given in the README, even though they have different signatures. So instead of replacing it, just add the second function.
