If you've managed to complete the level 2 - silver challenge without looking at the solution code, then it's time to push yourself and increase the difficulty even more. Complete this final challenge to get the gold medal.

1. Start by cloning a fresh copy of the app that includes all the code up until this point:

https://github.com/londonappbrewery/bitcoin-flutter-gold-start

At the moment our app can only fetch the bitcoin price depending on the selected currency.

But what if we wanted other cryptocurrency prices too?

2. If you look inside the coin_data.dart file, you'll find a const called cryptoList. This contains a List of Strings that represent 3 cryptocurrency symbols. BTC - Bitcoin, ETH - Ethereum and LTC - Litecoin.

3. Using what you have learnt in previous modules, update the code in the gold starter project to be able to display all three cryptocurrency prices in any selected currency.

Goal: By the end of this challenge, this is the functionality you should end up with:
