Effortlessly Make Network Requests in Flutter with Dio Library - Flutter

This is a Flutter application that uses the Dio package to make HTTP requests to an API and display the results in a ListView. The Post class represents a single post object that is returned from the API. It has three properties: id, title, and body. It also has a factory method fromJson that creates a Post object from a JSON object. The ApiService class is responsible for making HTTP requests to the API. It creates a Dio object with some default options, including the API base URL and timeout durations. It also adds an interceptor Log to log the request and response details. The fetchPosts method in the ApiService class sends a GET request to the /posts endpoint of the API and waits for a response. If the request is successful, it extracts the data property from the response and converts it to a list of Post objects using the map method and the fromJson factory method. Finally, it returns the list of Post objects. If the request fails, it throws an exception with an error
