Building a Notes App with Flutter & Hive

Why Hive?

Hive is a lightweight, blazing-fast key-value database written in pure Dart. It is perfect for offline-first apps.

Setup

dependencies:
  hive: ^2.2.3
  hive_flutter: ^1.1.0

Initializing Hive

await Hive.initFlutter();
final box = await Hive.openBox('notes');

Saving and Reading Notes

await box.put('note-1', 'Buy milk');
final note = box.get('note-1');

With a ValueListenableBuilder on the box, your UI updates automatically whenever the data changes.
