No type or protocol named 'FlutterPlugin'

When I try to flutter build ios or just run on iOS simulator, it fails with following error:

Failed to build iOS app

Thanks.

Hey @darshankawar thanks for the reply.

I checked that solution but I'm afraid of implementing it as there are many other configurations made to existing project for say implementing firebase and NotificationServiceExtensions etc. Also it is a live app on app store.

Isn't there any way to fix the existing project, please.

Hi @casualcoder404,
Can you try by upgrading shared_preferences plugin to latest version, run pub get, then do a flutter clean and then flutter run ?

Yes sir, I tried this but didn't help.

(I tried v 0.5.7+3 and not v 0.5.8 as it is giving some errors, but I don't think that matters)

Here's a screenshot from xcode. I don't think the issue is with any particular package, as the Semantic issue and Generic issue randomly shows up on any one of the packages.

Appdelegate.m

Those errors mean it can't find the Flutter.framework symbols.
What's the output of:

$ file ios/Flutter/Flutter.framework/Flutter

The workaround mentioned by @darshankawar worked. The only problem for me was changing the name to create new project, as it'll change other configurations such as app store id and firebase integration etc. But I was able to create a new project in different folder, with the same name. And copied lib, pubscec and android folder to it with some small changes to xcode and it worked.

Thanks everyone.
