Lemon Markets SDK

A simple way to access the lemon markets API (https://www.lemon.markets/) in dart / flutter

Create account for lemon markets

Currently the lemon market api is in beta and you can join the waitlist to get access (https://www.lemon.markets/waitlist)

Create an API-Key for accessing the lemon markets API

Get/Create your API-key from the https://dashboard.lemon.markets/

For this SDK you will always need an instance of LemonMarkets and an instance of AccessToken. You can specify in the AccessToken if you want to use real-money trading for this token.

import 'package:lemon_markets_client/lemon_markets_client.dart';
...

final LemonMarkets lemonMarkets = LemonMarkets();
AccessToken token = AccessToken(token: 'ADD_YOUR_TOKEN_HERE');

Search for instrument

  final LemonMarkets lemonMarkets = LemonMarkets();
  AccessToken token = AccessToken(token: 'ADD_YOUR_TOKEN_HERE');
  try {
    ResultList<Instrument> result = await lemonMarkets.searchInstruments(token, search: 'Tesla');
  } on LemonMarketsException catch (e) {
    debugPrint(e.toString());
  }

Create and activate an order

If you want to buy or sell an instrument you need two steps to do that.
First you must create an order and second you need to activate this order.
(More details for working with orders: https://docs.lemon.markets/working-with-orders)

Short example for BUY:

  final LemonMarkets lemonMarkets = LemonMarkets();
  AccessToken token = AccessToken(token: 'ADD_YOUR_TOKEN_HERE');

  TradingResult<CreatedOrder> result = await lemonMarkets.placeOrder(token, 'US88160R1014', OrderSide.buy, 5);
  String orderUuid = result.result!.uuid;
  ActivateOrderResult activateResult = lemonMarkets.activateOrder(token, orderUuid);  

Short example for SELL:

  final LemonMarkets lemonMarkets = LemonMarkets();
  AccessToken token = AccessToken(token: 'ADD_YOUR_TOKEN_HERE');

  TradingResult<CreatedOrder> result = await lemonMarkets.placeOrder(token, 'US88160R1014', OrderSide.sell, 5);
  String orderUuid = result.uuid;
  ActivateOrderResult activateResult = lemonMarkets.activateOrder(token, orderUuid);

Building this plugin

Running the example app

If you want to run the example app, you need to replace 'ADD_YOUR_TOKEN_HERE' in the LemonMarketsProvider with your token!
