finance 0.0.1

A Flutter plugin for retrieving financial quote prices.

A Flutter plugin for retrieving financial quote prices.

This package contains a set of high-level functions and classes that make it easy to retrieve stocks, commodities and cryptocurrencies quote prices. It's platform-independent.

Using

The easiest way to use this library is via the top-level functions. They allow you to make quote price requests with minimal hassle:

  final Map<String, Map<String, dynamic>> quotePrice = await Finance.downloadQuotePrice(
      QuoteProvider.yahoo, <String>['KO']);

  print('Number of quotes retrieved: ${quotePrice.keys.length}.');
  print('Number of attributes retrieved for KO : ${quotePrice['KO'].keys.length}.');
  print('Current market price for KO : ${quotePrice['KO']['price']}.');

If you're making multiple quote requests to the same server, you can request all of them in a single function call:

  final Map<String, Map<String, dynamic>> quotePrice = await Finance.downloadQuotePrice(
      QuoteProvider.yahoo, <String>['KO', 'GOOG']);

  print('Number of quotes retrieved: ${quotePrice.keys.length}.');
  print('Number of attributes retrieved for KO : ${quotePrice['KO'].keys.length}.');
  print('Current market price for KO : ${quotePrice['KO']['price']}.');
  print('Number of attributes retrieved for GOOG : ${quotePrice['GOOG'].keys.length}.');
  print('Current market price for KO : ${quotePrice['GOOG']['price']}.');

If you want all available quote data from the selected provider, you can request it with the function call:

  final Map<String, Map<String, dynamic>> cryptoQuoteRaw = await Finance.downloadRawQuote(
      QuoteProvider.coincap, <String>['bitcoin', 'ethereum']);

  print('Number of quotes retrieved: ${cryptoQuoteRaw.keys.length}.');
  print('Number of attributes retrieved for bitcoin : ${cryptoQuoteRaw['bitcoin'].keys.length}.');
  print('Current market price for bitcoin : ${cryptoQuoteRaw['bitcoin']['priceUsd']}.');
  print('Number of attributes retrieved for ethereum : ${cryptoQuoteRaw['ethereum'].keys.length}.');
  print('Current market price for ethereum : ${cryptoQuoteRaw['ethereum']['priceUsd']}.');
