ios deployment target to at least 14.0

[Cyrille37]

Hi,

Thanks you very much for this really great Flutter plugin 💌 .

After installed the plugin workmanager the iOS build failed because of minimum deployment target to at least 14.0 :

...
CocoaPods could not find compatible versions for pod "workmanager_apple"
...
The plugin "workmanager_apple" requires a higher minimum iOS deployment version than your application is targeting.
To build, increase your application's deployment target to at least 14.0 as described at https://flutter.dev/to/ios-deploy
Error running pod install

I did these change in ios/Runner.xcodeproj/project.pbxproj :

IPHONEOS_DEPLOYMENT_TARGET = 14.0;

And the build success 🤗

Updating the documentation QuickStart / Platform Setup / iOS would be a good point 😉 .

Thanks again for sharing this great work !
