flutter run on iPhone simulator stucks on 'Xcode build done'. (it runs well in android emulator)

ios xcode macos flutter ios-simulator

The problem was that I erased all components in 'Copy Bundle Resources'. I added Main.storyboard on it, and the app runs fine.

Question

Hello, I'm having difficulty while running my Flutter App on iPhone simulator. It stucks on 'Xcode build done'. BTW, It runs very well on Android emulator.

It's my first time to ask a question here, so please let me know if more information is needed, or something seems inappropriate. Any kind of help (or comment) would be appreciated. Thank you.

The video of trying to launch the app manually: https://user-images.githubusercontent.com/60031762/141050073-648a9893-0e33-425e-9c9d-24966bf1be39.mov

p.s. I also opened an issue on flutter github: https://github.com/flutter/flutter/issues/93361

Below are details: steps to reproduce and logs.

Steps to Reproduce

OS: macOS Big Sur 11.6, connected to USB Network(Hotspot) of my iPhone 11 pro(iOS 15.1).

Clone https://github.com/kws1207/friendship/tree/main/where_to_eat and open the project.
Run Simulator, open iPhone 12 Pro Max, iOS 14.4.
Execute flutter run.
Select the Simulator opened in 2.

Expected results:

Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running Xcode build...                                                  
 └─Compiling, linking and signing...                         8.3s
Xcode build done.                                           268.6s
Installing and launching...
Flutter run key commands.
r Hot reload. 🔥🔥🔥
R Hot restart.
h List all available interactive commands.
d Detach (terminate "flutter run" but leave application running).
c Clear the screen
q Quit (terminate the application on the device).

Running with unsound null safety
For more information see
https://dart.dev/null-safety/unsound-null-safety

Actual results:

Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running Xcode build...                                                  
 └─Compiling, linking and signing...                         8.3s
Xcode build done.                                           268.6s
(it stucks here)

I have added full code.

"import Firebase" was missing. However, the problem was not solved. I'm struggling with the error [Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'Main' in bundle NSBundle]. Thank you.

Hello, thank you for commenting. Currently I'm struggling with an error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'Main' in bundle NSBundle. Can you please help me?

after adding this please check with flutter clean, flutter pub get and flutter run command or close the xcode reopen.

Since that link is about actual iOS device, it seems not the case.
