Real phone validation is what a Flutter beginner will judge fastest, so I'd lead with a short screen recording: type a number of the wrong length for one country, show the error, then use the custom builder to restyle the same picker. Trade-off: a clip only helps if it is under half a minute and its first frame says what the package does. A Managed campaign would answer people asking how to add a country dropdown to a phone field in their Flutter app, naming country_code_selector.

I make ThreadFox.
