Flutter has a robust caching mechanism and performance optimization techniques to handle network requests. Here’s how Flutter handles caching and performance optimization for network requests:
Caching Mechanism:
Flutter offers a built-in cache management system that makes caching transparent and efficient. It provides the flutter_cache_manager package, which allows you to cache resources like images, files, and other network responses. The cache manager handles the storage and retrieval of cached resources based on different cache policies.
With the cache manager, you can define cache policies to suit your requirements. For example, you can set a cache policy to cache resources for a specific duration or cache them indefinitely. This ensures that frequently requested resources are readily available, minimizing network traffic and improving app performance.
Efficient Network Request Handling:
Flutter utilizes future-based APIs to handle network requests efficiently. Future objects represent values or errors that will be available in the future, allowing non-blocking execution of network requests. By using asynchronous programming, Flutter ensures that network requests don’t block the user interface, providing a smooth user experience.
When making network requests in Flutter, you can use the http package or other networking libraries that support future-based APIs. These APIs allow you to perform network requests in a concurrent manner, optimizing the execution and avoiding delays in app responsiveness.
