When I first wrote this answer I somehow overlooked that I've only worked on Android via React Native!

Anyway, here's my JavaScript solution that works with or without ES6 support.

    function countryCodeToFlagEmoji(country) {
      return typeof String.fromCodePoint === "function"
        ? String.fromCodePoint(...[...country].map(c => c.charCodeAt() + 0x1f185))
        : [...country]
            .map(c => "\ud83c" + String.fromCharCode(0xdd85 + c.charCodeAt()))
            .join("");
    }

console.log(countryCodeToFlagEmoji("au"));
console.log(countryCodeToFlagEmoji("aubdusca"));

If you want to pass in the country codes as capital letters instead, just change the two offsets to 0x1f1a5 and 0xdda5.
