React Native Phone Input

A phone field looks trivial until it ships internationally: country codes, search, flags on two platforms, and a validation rule that differs per country.

• Built the field around Google libphonenumber so validation follows each country's own rule rather than a regular expression.
• Shipped two layouts and a documented style surface, because the component has to sit inside somebody else's design system without being forked.
• Typed the public API end to end and kept the country list searchable with emoji flags on both iOS and Android.

• Around 3,400 npm downloads in the 30 days to August 2026, on version 3.8.0.
• Five forks on GitHub — the component is being adapted, not only installed.
