Complete this challenge to get the bronze medal. After completing this challenge, you can push yourself further by continuing to complete to the silver medal in the next lesson.
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-challenge-start
2. Run the app, it currently has a single Text Widget, that displays 1 BTC = ? USD

3. Using what you have learnt in previous modules to display the latest price of 1 Bitcoin (BTC) in US dollars (USD).
You'll need the BitcoinAverage API for Ticker Data (Per Symbol) to achieve this:
https://apiv2.bitcoinaverage.com/#ticker-data-per-symbol
The value we're interested from the API is the last price of Bitcoin in USD.

You'll want to write all the networking/request/parsing code inside a method called getCoinData() in the CoinData class in the coin_data.dart file.
Goal: By the end of this challenge, this is the functionality you should end up with:

NOTE: The CupertinoPicker/DropdownMenu is not supposed to work yet.
Hint: You'll need the http and dart:convert packages.
