Why my Flutter app not running on iPhone?

Question

I successfully run my app on simulator(iPhone 12, iOS 14.5), but when it running on real iPhone 11 Pro Max(iOS 14.7.1) I facing just a black screen. Here is the output from Xcode:

UPDATED

To fix this, remove run rm -rf ~/flutter/bin/cache . Then run flutter run (you should run your app from terminal instead of IDE in order to Flutter download missing files). It's somehow works now.

Answer 1

Deleting the cache using rm -rf ~/flutter/bin/cache worked for me. This issue seems to have been caused by a bad Flutter installation. Running flutter pub get after deleting the cache should download the packages again and rebuild the project.
