Can't run application

[locskot]

There is a problem during the building step.
My steps:

1. cd ios
2. flutter clean
3. flutter pub get
4. pod update (log item is: Installing flutter_call_kit (0.0.1))

Here is the flutter doctor -v output

I rebuilt yesterday and got the same error. I thought that the major version of flutter upgrade I was doing was the problem, but it doesn't seem to be.

Cause of problem: AVFoundation.framework doesn't seem to be included at build time (exact cause is unknown)

1. First found solution (settings disappear when using flutter clean)
   flutter_call_kit> Build Phases> Link Binary With Libraries
   

2. Source Modification
   ios> flutter_call_kit.podspec
   Add the following.

s.preserve_paths = 'AVFoundation.framework'
s.xcconfig = { 'OTHER_LDFLAGS' => '-framework AVFoundation' }
s.vendored_frameworks = 'AVFoundation.framework'

#23 Hope this solves the problem well.

Anyone can run on xcode 13 beta? Still getting same error after added AVFoundation.framework to Link Binary With Libraries and update flutter_call_kit.podspec.
