Hive vs ObjectBox vs SQLite

Local database options for Flutter:

Hive

Type: NoSQL (key-value) Performance: Very fast

dartCopy
final box = Hive.box('users');
await box.put('user1', User(name: 'Alice'));
User user = box.get('user1');

Pros:

• Extremely fast
• No schema needed
• Easy to use
• Great for simple data

Cons:

• Limited querying
• No complex relationships

ObjectBox

Type: NoSQL (object database) Performance: Very fast

dartCopy
final user = User(name: 'Alice');
await store.box<User>().put(user);

Pros:

• Very fast
• Strong typing
• Good queries
• Relations support

Cons:

• Code generation required
• Learning curve

SQLite

Type: SQL (relational) Performance: Good

dartCopy
Database db = await openDatabase('app.db');
await db.execute('CREATE TABLE users(id INT, name TEXT)');

Pros:

• Powerful queries
• Complex relationships
• Industry standard
• SQL knowledge

Cons:

• More boilerplate
• Slower than Hive/ObjectBox

Comparison

Choice: Hive for simple, ObjectBox for medium, SQLite for complex apps.
