A Flutter project. I built a crypto portfolio with a very simple kept overview of your balances and the total value. You can add the balances of your exchanges via the API of Binance, Bittrex, HitBTC, Coinbase or Coinbase Pro.

When you are just interested how I connect the exchanges, then go to 'lib/utility/fetch_exchange_data.dart'

• API support
• fix bugs for public build
• add fiat value to specific coin
• add more exchanges(HitBTC recenetly added)
• manually add exchanges/coins
• different currency support (EUR, USD, GBP)
• maybe improve loading speed
