API Integration in Flutter: Best Practices and Common Scenarios
In this interview question, you'll be asked to demonstrate how to integrate REST APIs in a Flutter application. The focus will be on making HTTP requests using Dart's http package or other tools like Dio. You'll need to showcase how to handle various HTTP methods (GET, POST, PUT, DELETE), parse JSON responses, manage error handling for network failures or invalid responses, and implement retry mechanisms. Additionally, you should explain how to handle headers, authentication (e.g., using tokens), and optimize API calls for performance and responsiveness.
