This looks like an issue with the native iOS side of the project, not the dart side. Try the following and let me know how it goes. From the root of your Flutter project:

• Clean the Flutter workspace

  flutter clean

• Clean the Flutter dependency cache. Reinstalling the dependencies later with flutter pub get might take a while but this will make sure none of your plugins have been corrupted.

  flutter pub cache clean

• Delete Xcode derived data:

  rm -rf ~/Library/Developer/Xcode/DerivedData

• Delete the iOS directory:

  rm -rf ios

• Recreate the iOS directory:

  flutter create .

Navigate to the iOS directory with cd ios. From the iOS directory:

• Ensure your CocoaPods is up-to-date:

  sudo gem install cocoapods

• Update the CocoaPods repository:

  pod repo update

• Install iOS dependencies:

  pod install

• Get Flutter dependencies:

  flutter pub get

If you're still running into this problem after these steps, there's probably an issue with your iOS simulator. With your iOS simulator running, reset the simulator with Device > Erase All Content and Settings from the simulator menu.

Let me know if this doesn't resolve your issue.
