Is it possible to get the country code or flag from FiatCurrency?

Hi! First of all, thank you for this amazing package 🙌

I’m currently using currency_picker, and I’d love to migrate to your package. However, I noticed that the currency search only shows the currency name and symbol.

It would be really helpful if it could also display the country flag or at least the country/ISO code, so developers can easily map it to a flag on their side.

I tried extracting the first letters from the ISO code, but unfortunately that doesn’t work reliably for all currencies.

Is there any recommended way to handle this? Or are there plans to support this in the future?

Thanks in advance! 🚀

Hey @diegoleft it's now WIP (I only need to provide updated changelog, bump pubspec.yaml, and check regressions with benchmarks) in the main branch (you can reference to git now to check). I will release v4.0.0 of world_countries in a few days. It will contain country flags in the currency picker by default (you will also be able to provide your custom itemBuilder, as the current API is not very DevEx-friendly). Thanks for the ⭐

Thanks @diegoleft, in the meantime, I can help you answer any questions about the new API or help with your specific use case. If you can share with me your scenario and expectations, I can provide you example that should fulfill your needs 🙏🏻

Hey @diegoleft, just a heads up - world_countries v4 is live, don't forget to provide TypedLocaleDelegate to your app's localizationsDelegates list, it will do all the magic and caching of the currency > country flags mappings. Feel free to open any other issue or discuss if you have any questions, feedback, feature requests, or other concerns. Thanks again!
