Accessing/Implementing REST API's

Fetching data from the internet is necessary for most apps. Luckily, Dart and Flutter provide tools, such as the http package, for this type of work. http is a Future-based library and uses await and async features. It provides many high level methods and simplifies the development of REST based mobile applications.

Basic Concepts

https provides a high level class and http to do web requests.

• http class provides functionality to perform all types of HTTP requests.
• http methods accept a url, and additional information through Dart Map (post data, additional headers, etc.,). It requests the server and collects the response back in async/await pattern. For example, the below code reads the data from the specified url and print it in the console.

Some core methods are:

Introduction

I am Ayesha Iftikhar and I am creating this gist to keep all the most commonly used codes in one place. This will have all common code snippets which are basic building blocks of any flutter application. Like, basic widgets and their commonly used properties.
