Creating a Base API class:

Our first step is to build a BaseAPI class to hold all of the URL’s of our API. In my _How To Make Flutter API Calls Easy_I taught you how to use class inheritance as a means of simplifying and organizing your API calls. This class isn’t to complex it just stores the routes we will be requesting, check out the code below.

Class BaseAPI{

    static String base = "http://localhost:3000"; 
    static var api = base + "/api/v1";
    var customersPath = api + "/customers";
    var authPath = api + "/auth"; 
   // more routes
   Map<String,String> headers = {                           
       "Content-Type": "application/json; charset=UTF-8" };                                      

}

Ultimately creating our Base class makes it easier for us to manage our API endpoints.
