Overview

Version 2 on the way!

I'm currently rewriting the application from scratch to remove a lot of the ugly code, conform better to modern flutter best practices with regards to State Management and Routing and splitting up widgets before they become monsters.

The code for the v1 can be found in the legacy/v1 branch, whats currently available in master is pretty bare bones functionality wise, but should serve pretty well for a starter for other apps.

Updated design

Todo

  • Get prices
  • Display all prices
  • Sort all prices based on price, 24h gain/loss
  • Add coin to favorites
  • list favorites
  • Add wallets (both via pasting address or scanning QR code)
  • Remove wallet
  • Get wallet value
  • Single coin view
  • Single coin graph
  • wallet view
  • Cool but pointless animations

Version 1

can be found in the branch legacy/v1 for posterity.

Getting Started

  1. Install Flutter
  2. Clone the repo
  3. Run flutter run (make sure to have an emulator running).

Recent changes

  • Way faster load times in portfolio. Can be done even faster if the coin values are fetched (or even prefetched) and graph is continuously built after the wallet stream emits a coin object.
  • Portfolio update look and feel

Todo

  • Maybe currency icons?
  • Loading indicator.
  • Graph out historical data for a currency
  • Make sure that the graph is actually correct. God knows what it's displaying now.
  • Error messages when timeline/order data for a currency couldn't be found.
  • Scan QR-code to add wallet to wallet list
  • Remove wallet from list
  • Dynamic portfolio based on address (ETH + ERC20-tokens, LTC, BTC, BCH, DASH and ADA for now)
  • Ability to add individual assets in addition to wallets
  • Add more information in the details view (Circulating supply, ATH, 24h hi/low)
  • Dark mode

  • CoinGraph text and indicator dots are covered by shader

    CoinGraph text and indicator dots are covered by shader

    The gradient shader that gives the coin chart a pink->blue gradient also covers the text and the hi/low/current indicators, meaning that they get the same hues. These should ideally be gray/white which could be achieved if they are moved to their own CustomPainter with the same X/Y calculations and drawn over the ShaderMask in coin-graph.dart using a Stack widget.

    Create WalletService and update WalletModel

    WalletModel needs the following public method

    class WalletValue {
  double amount;
  double value;
}

    WalletContents getContents(Wallet wallet);

    And WalletService needs the following methods, since they will be pretty different API calls with different methods.

WalletContents _getEthereumValue(String address);

  • Use bezier curves for coin graph

    Use bezier curves for coin graph

    Currently the coin graph is using the path.lineTo function, causing the lines to be straight between nodes. It would be nice to use path.relativeCubicTo or path.relativeConicTo to make the graph prettier.
