Networking in Flutter using the http package

Handling network requests in Flutter can be efficiently managed using the http package, which allows developers to perform REST API operations such as GET, POST, PUT, and DELETE. The article provides a step-by-step guide to implementing these operations, starting with setting up a Flutter project and integrating the http package. It demonstrates fetching and sending data using JSONPlaceholder's sample API, creating a model class to manage the API data, and utilizing JSON serialization for easier data handling. The PostClient class is introduced to encapsulate the network request logic, and the HomePage widget is created to build a user interface that interacts with these network requests. Testing is facilitated using the Mockito package, which helps simulate network responses for verification. Additionally, the article suggests the Dio package for those seeking more advanced features and control over network requests.
