Learn to use hive, offline key-value database for flutter, storing data on device with boxes. Initialize hive, install dependencies, and build a UI to perform create read update delete.
Open and reference Hive boxes, decide when to keep them open or close them, and use put, get, update, and delete for key-value data and auto-incremented indexes.
Implement five methods on the home screen to perform create, read, update, and delete with a local Hive box, storing and retrieving a name by key for offline Flutter apps.
Explain how hive type adapters encode and decode a to do model with title and completed fields, generate adapters with hive generator, and register them before opening the box.
Build a flutter to-do app using Hive offline database. Add a screen to input a todo title and save it with completed as false, then display todos with ValueListenableBuilder.
Update and delete todos in a Flutter Hive offline database by toggling completion with a checkbox, updating the list, applying green text for done items, and showing a snackbar feedback.
Storing data locally and persisting between app launches is one of the fundamental concepts of any mobile app development process. Almost every app requires that you handle data — from storing customer information for a food delivery app, to the number of points scored in a game or a simple value to understand whether the user has turned on dark mode during their last visit.
Hive is a quick, lightweight, NoSQL database for flutter and dart applications. Hive is truly helpful if you need a straightforward key-value database without numerous relations and truly simple to utilize. It is an offline database(store data in local devices). It has no native dependencies (it runs on Flutter Web!) can be the ideal choice. Hive bolsters all stages upheld by Flutter.
We will explore the Hive DataBase With TypeAdapter In Flutter. We will also implement a demo program, create a todo app using hive packages, and use them in flutter applications.
Why Hive DataBase?:
It’s the most efficient database in terms of speed and performance compared to SQFlite and SharedPrefrences.
It provides a straightforward way to perform basic (CRUD) operations.
Advantages:
Cross-platform: since there are no native dependencies on pure Dart — mobile, desktop, browser.
High performance.
Built-in strong encryption.
NO native dependencies.
