alpha_vantage_package #
A new Flutter package for using alpha vantage api.
You will need your own API key from https://www.alphavantage.co/ (it's free) to use stocks other than MSFT
This was refactored and updated from the original source: https://github.com/jcmelend/flutter_alpha_vantage_api so credits to the maker.

Usage #
Add the following import statement where you need to use this package libraries: import 'package:alpha_vantage_package/alpha_vantage_package.dart';
There are four libraries to use to call Alpha Vantage rest api: TimeSeries.dart, SectorPerformances.dart, ForeignExchange.dart, CryptoCurrencies.dart, and TechnicalIndicators.dart.
Example:
import 'package:flutter_test/flutter_test.dart';
import 'package:flutter_alpha_vantage_package/alpha_vantage_package.dart';
void main() async {
test('Intraday', () async {
final timeSeries = new TimeSeries("YourAlphaVantageAPIKey");
//get the hourly time series for Microsoft with to-the-minute updates. You can change this.
JSONObject json = await timeSeries.getIntraday("MSFT");
var data = json.getJSONMap()["Time Series (1min)"];
//convert to map to get specific data like the amount during lcose
var data2 = Map<String, dynamic>.from(data);
data2.forEach((k,v) => print(v["4. close"]));
//Use get method to search entire json for key for stock
expect(json.get("2. Symbol"), "MSFT");
// Use map to find stock symbol
expect(json.getJSONMap()["Meta Data"]["2. Symbol"], "MSFT");
print(json.getJSONMap());
});
test('Intraday', () async {
final technicalIndicator = new TechnicalIndicators("YourAlphaVantageAPIKey");
//get SMA for microsoft
JSONObject json = await technicalIndicator.getSMA("MSFT");
// Use get method to search entire json for key for stock
expect(json.get("1: Symbol"), "MSFT");
// Use map to find stock symbol
expect(json.getJSONMap()["Meta Data"]["1: Symbol"], "MSFT");
print(json.getJSONMap());
});
