Fixing a dependencies problem in Flutter. Says build failed because of something related to Apple Watch but I am not using Apple Watch - flutter

Question

I am running into a problem when trying to build my Flutter app. I am using VS Code and the latest versions of Flutter and Dart. I think I have a problem with dependencies, but not sure. I have the following dependencies in my pubspec.yaml file:
http: ^0.13.4
youtube_player_flutter: ^8.0.0
percent_indicator: ^3.4.0
endless: ^1.6.0
flutter_staggered_grid_view: ^0.6.1
transparent_image:
accordion: ^2.2.3
like_button: ^2.0.4
easy_firebase_auth: ^3.2.0
flutter_inappwebview: ^5.4.3+7
webview_flutter: ^3.0.4
firebase_core: ^1.6.0
cloud_firestore: ^2.5.1
url_launcher: ^6.1.2
geocoding: ^2.0.4
sign_in_with_apple: ^3.3.0
I run into a problem when I do a flutter build. I get the following error messages:

I am pretty new to Flutter & Dart. What can I try?

Answer 1

I have similar error and after many tries I solved in this way:
Update MacOS
Update Xcode and command lines tools
Run flutter pub upgrade, flutter pub get in the project folder
Delete podfile.lock in ios folder of the project
Run cd ios, pod repo update, pod install in the project folder

Answer 2

Delete Runner.xcworkspace,Podfile.lock
then follow these steps
