Store objects

Hive not only supports primitives, lists and maps but also any Dart object you like. You need to generate a type adapter before you can store objects

Hive was written with Flutter in mind. It is a perfect fit if you need a lightweight datastore for your app. After adding the required dependencies and initializing Hive, you can use Hive in your project:

What are boxes?

All data stored in Hive is organized in boxes. A box can be compared to a table in SQL, but it does not have a structure and can contain anything.

For a small app, a single box might be enough. For more advanced problems, boxes are a great way to organize your data. Boxes can also be encrypted to store sensitive data.
