Caching is the process of temporarily storing frequently used data or information in a location where it can be accessed quickly and easily, instead of having to retrieve it from its original source every time it is needed.
Caching API responses can improve the performance of your Flutter app by reducing the number of requests made to the server. Transform your app idea into reality with our Flutter app development services. In Flutter, caching can be implemented using various packages. We will be discussing the famous and good ones such as shared_preferences, hive, sembast, sqflite, and others.
Let’s start with the simple one i.e. shared_preferences package:
flutter pub get
Note: The shared_preferences package is not suitable for storing large amounts of data or complex data structures. For more advanced caching needs, you might consider using other packages like hive, sembast, or sqflite.
Hive is a NoSQL based database that is optimized for fast read and write operations. Hive is ideal for storing small to medium-sized data sets that can fit in memory, and it is suitable for use cases that require fast read and write performance, such as caching, user preferences, and small data sets.
To integrate Hive with Flutter, you can follow these steps:
This way we can implement API caching with Hive in the Flutter app. We can adjust the _cacheTimeout value to set the expiration time of cached responses according to our app’s need.
If you are comfortable with sqflite package, you can use the same concept with it. Checkout our blog on using sqflite package.
That’s it from my side. Thanks for reading this article ❤
