sqflite Database Instrumentation

(New in version 7.2.0)

The sentry_sqflite package provides sqflite 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 sqflite span will not be sent to Sentry.
  • The spans' operation are either db, db.sql.execute, db.sql.query or db.sql.transaction. Its description is the SQL statement using placeholders instead of its values due to the possibility of containing PII.

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_sqflite dependency to install the sqflite database instrumentation.

dependencies:
  sentry_flutter: ^8.0.0
  sentry_sqflite: ^8.0.0
  sqflite: ^2.0.0

There are multiple ways to configure the sqflite database instrumentation:

By using the global databaseFactory, (which is used by the openDatabase method). With this approach, every call to openDatabase will be instrumented, including from other packages:

Copied
import 'package:sentry_sqflite/sentry_sqflite.dart';
import 'package:sqflite/sqflite.dart';

databaseFactory = SentrySqfliteDatabaseFactory();
final database = await openDatabase('path/to/db');

If you're using the FFI factories, you can instrument the SentrySqfliteDatabaseFactory with its factory:

Copied
import 'package:sentry_sqflite/sentry_sqflite.dart';
import 'package:sqflite/sqflite.dart';

databaseFactory = SentrySqfliteDatabaseFactory(databaseFactory: databaseFactoryFfi);
final database = await openDatabase('path/to/db');

Use the openDatabaseWithSentry wrapper - with this approach only the database opened with this method will be instrumented:

Copied
import 'package:sentry_sqflite/sentry_sqflite.dart';
import 'package:sqflite/sqflite.dart';

final database = await openDatabaseWithSentry('path/to/db');
// or final database = await openReadOnlyDatabaseWithSentry('path/to/db');

Use the SentryDatabase wrapper which can be used to instrument any Database instance:

Copied
import 'package:sentry_sqflite/sentry_sqflite.dart';
import 'package:sqflite/sqflite.dart';

final database = await openDatabase('path/to/db');
final sentryDatabase = SentryDatabase(database);

Copied
import 'package:sentry_sqflite/sentry_sqflite.dart';
import 'package:sqflite/sqflite.dart';

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

  // You can also use the other configuration methods
  final db = await openDatabaseWithSentry(inMemoryDatabasePath);

  await db.execute('''CREATE TABLE Product (id INTEGER PRIMARY KEY,title TEXT)''');
  final dbTitles = <String>[];
  for (int i = 1; i <= 20; i++) {
    final title = 'Product $i';
    dbTitles.add(title);
    await db.insert('Product', <String, Object?>{'title': title});
  }

  await db.query('Product');

  await db.transaction((txn) async {
    await txn
    .insert('Product', <String, Object?>{'title': 'Product Another one'});
    await txn.delete('Product',
    where: 'title = ?', whereArgs: ['Product Another one']);
  });

  await db.delete('Product', where: 'title = ?', whereArgs: ['Product 1']);

  await db.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 sqfliteTest.
