What happens if your app's Info.plist lacks the NSCameraUsageDescription key?

Your Flutter app uses the camera, but the Info.plist file does not include the NSCameraUsageDescription key. What will happen when the app runs on a real iOS device?

A The app will show a default system message explaining camera use.

B The app will access the camera without any warning to the user.

C The app will crash when trying to access the camera.

D The app will ignore camera access and continue running.

💡 Hint

iOS requires permission messages for privacy-sensitive features.

Without NSCameraUsageDescription, iOS will crash the app when it tries to access the camera because it lacks a privacy usage description.

What is the correct way to specify the app version and build number in Flutter's pubspec.yaml for iOS submission?

In your Flutter project's pubspec.yaml, how should you write the version field to set app version 2.3.1 and build number 45 for iOS submission?

Flutter

version: ?

A 2.3.1+45

B 2.3.1-45

C 2.3.1.45

D version: 2.3.1+45

💡 Hint

The format is version+buildnumber without extra keys.

Flutter uses the format 'x.y.z+build' in pubspec.yaml to set version and build number for iOS and Android.
