Isar Database Instrumentation for Flutter

Learn more about the Sentry Isar Database Instrumentation for the Flutter SDK.

(New in version 7.16.0)

Isar is a fast cross-platform database for Flutter. The sentry_isar package provides Isar support for database instrumentation and allows you to track the performance of your queries.

The created spans attach to the active span. In transaction mode, that's the transaction bound to the scope; in stream mode, it's the span started with Sentry.startSpan(). If no span is active, the Isar span won't be sent to Sentry.

Before starting, ensure:

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

Add the sentry_isar dependency to install the Isar database instrumentation.

pubspec.yaml
Copied
dependencies:
sentry_flutter: ^10.0.0
sentry_isar: ^10.0.0
path_provider: ^2.0.0

Use SentryIsar to initialize the instance:

Copied
import 'package:path_provider/path_provider.dart';
import 'package:sentry_flutter/sentry_flutter.dart';
import 'package:sentry_isar/sentry_isar.dart';

import 'user.dart'; // Import your Isar model instead

final dir = await getApplicationDocumentsDirectory();
final isar = await SentryIsar.open(
  [UserSchema],
  directory: dir.path,
);

To use the Transaction Mode tab, set options.traceLifecycle = SentryTraceLifecycle.static during SDK initialization.

Copied
import 'package:path_provider/path_provider.dart';
import 'package:sentry_flutter/sentry_flutter.dart';
import 'package:sentry_isar/sentry_isar.dart';

import 'user.dart'; // Import your Isar model instead

Future<void> runApp() async {
  await Sentry.startSpan('isarTest', (span) async {
    final dir = await getApplicationDocumentsDirectory();

    final isar = await SentryIsar.open(
      [UserSchema],
      directory: dir.path,
    );

    final newUser = User()
      ..name = 'Joe Dirt'
      ..age = 36;

    await isar.writeTxn(() async {
      await isar.users.put(newUser); // insert & update
    });

    final existingUser = await isar.users.get(newUser.id); // get

    await isar.writeTxn(() async {
      await isar.users.delete(existingUser!.id); // delete
    });
  }, parentSpan: null);
}

To view the recorded transaction, log into sentry.io. Use the left sidebar to navigate to the Performance page. Select your project and scroll down to the transactions table to see the just recorded transaction with the name isarTest. You can also use the search bar to find the transaction. Click on the transaction to open its Transaction Summary page for more performance details.

Database spans identify the database system with db.system.name (isar) and the database name with db.namespace, when available. Use these keys in queries and span-filtering callbacks.

Collection names use db.collection.name.

Database breadcrumbs also use db.system.name and db.namespace.
