/// instance is properly initialized before it can be accessed.

/// The `initializeIsar()` method is used to initialize the Isar instance by
/// opening the database with the provided schema. Make sure to call this before
/// calling anything else!. The `isar` getter returns the
/// Isar instance, throwing an exception if the instance is not yet initialized.
