HasUuids

The HasUuids mixin configures the model to use a UUID (v4) string as its primary key instead of an auto-incrementing integer.

class Document extends Model with HasUuids {
  @override
  String get table => 'documents';
}

Behavior

• Auto-Generation: If the id is null when save() is called, a new UUID v4 is generated and assigned.
• Non-Incrementing: Sets incrementing to false, preventing the ORM from trying to fetch the last insert ID as an integer.

final doc = Document();
doc.title = 'Report';
await doc.save();

print(doc.id); // "550e8400-e29b-41d4-a716-446655440000"
