  // Create a new in-memory database. To use a database backed by a file, you
  // can replace this with sqlite3.open(yourFilePath).

  // Create a table and insert some data
  db.execute('''

  stmt
    ..execute(['The Beatles'])
    ..execute(['Led Zeppelin'])
    ..execute(['The Who'])
    ..execute(['Nirvana']);

  // Dispose a statement when you don't need it anymore to clean up resources.
  stmt.dispose();

  // You can run select statements with PreparedStatement.select, or directly
  // on the database:
  final ResultSet resultSet =
      db.select('SELECT * FROM artists WHERE name LIKE ?', ['The %']);

  // You can iterate on the result set in multiple ways to retrieve Row objects
  // one by one.
  for (final Row row in resultSet) {
    print('Artist[id: ${row['id']}, name: ${row['name']}]');
  }

  // Register a custom function we can invoke from sql:
  db.createFunction(
    functionName: 'dart_version',
    argumentCount: const AllowedArgumentCount(0),
    function: (args) => Platform.version,
  );
  print(db.select('SELECT dart_version()'));

  // Don't forget to dispose the database to avoid memory leaks
  db.dispose();
