flutter_iexcloud_api 1.0.0

Flutter API Client to retrieve financial data using IEX Cloud data provider.

flutter_iexcloud_api

The IEX Cloud API client based on REST, has resource-oriented URLs, returns JSON-encoded responses, and returns standard HTTP response codes.

Note:

• IEX Cloud authenticates your API requests using your account’s API tokens. To use any IEX Cloud API, you must pass an API token with each request. If you do not include your API token when making an API request, or use one that is incorrect or disabled, IEX Cloud returns an error.
• Work in progress, Only REST Requests are supported.

Add dependency

dependencies:
  flutter_iexcloud_api: ^1.0.0

Super simple to use

import 'package:flutter_iexcloud_api/flutter_iexcloud_api.dart';

late final IEXClientApi service = IEXClientApi(
  token: "<Your Token>",
);

final response = await service.cryptocurrencyPrice("btcbusd");

Configuration

property	description	default
token	(required) API Token provided by iexcloud	-
apiVersion	(required) iexcloud API Version	stable (see: ApiVersion)
connectTimeout	It occurs when url is opened timeout.	5000
sendTimeout	It occurs when url is sent timeout.	30000
receiveTimeout	It occurs when receiving timeout.	30000

Interceptors

For each client instance, We can add one or more interceptors, by which we can intercept requests, responses and errors before they are handled by then or catchError.

Simple interceptor example

import 'package:dio/dio.dart';
class CustomInterceptors extends Interceptor {
  @override
  void onRequest(RequestOptions options, RequestInterceptorHandler handler) {
    print('REQUEST[${options.method}] => PATH: ${options.path}');
    return super.onRequest(options, handler);
  }
  @override
  Future onResponse(Response response, ResponseInterceptorHandler handler) {
    print('RESPONSE[${response.statusCode}] => PATH: ${response.request?.path}');
    return super.onResponse(response, handler);
  }
  @override
  Future onError(DioError err, ErrorInterceptorHandler handler) {
    print('ERROR[${err.response?.statusCode}] => PATH: ${err.request.path}');
    return super.onError(err, handler);
  }
}

Registering the Interceptor

late final IEXClientApi service = IEXClientApi(
  token: "<Your Token>",
);
service.addInterceptor(CustomInterceptors());

Cleaning all interceptors

late final IEXClientApi service = IEXClientApi(
  token: "<Your Token>",
);
service.clearInterceptors();
