Hive Database Instrumentation

(New in version 7.13.1)

Hive is a lightweight and fast key-value database for Flutter and Dart applications. The sentry_hive package provides Hive support for database instrumentation and allows you to track the performance of your queries.

The created spans will be attached to the transaction on the scope - if no transaction is on the scope the Hive span will not be sent to Sentry.

Before starting, ensure:

  1. The Sentry Flutter SDK is initialized. Learn more here.
  2. Performance Monitoring is set up. Learn more here.

Add the sentry_hive dependency to install the Hive database instrumentation.

pubspec.yaml
Copied
dependencies:
sentry_flutter: ^8.0.0
sentry_hive: ^8.0.0
path_provider: ^2.0.0

Use SentryHive to initialize the instance:

Copied
import 'package:path_provider/path_provider.dart';
import 'package:sentry_hive/sentry_hive.dart';

final appDir = await getApplicationDocumentsDirectory();
SentryHive.init(appDir.path);

Copied
import 'package:sentry_hive/sentry_hive.dart';

Future<void> hiveTest() async {
  final tr = Sentry.startTransaction(
    'hiveTest',
    'db',
    bindToScope: true,
  );

  final appDir = await getApplicationDocumentsDirectory();
  SentryHive.init(appDir.path);

  final catsBox = await SentryHive.openBox<Map>('cats');
  await catsBox.put('fluffy', {'name': 'Fluffy', 'age': 4});
  await catsBox.put('loki', {'name': 'Loki', 'age': 2});
  await catsBox.clear();
  await catsBox.close();

  SentryHive.close();

  await tr.finish(status: const SpanStatus.ok());
}

To view the recorded transaction, log into sentry.io and open your project. Clicking Performance will open a page with transactions, where you can select the just recorded transaction with the name hiveTest.
