init method

Future<void> init()

Pre-initializes the data, so that it is accessible synchronously.

Implementation

Future<void> init() async {
  await _guard.protect(() async {
    if (_initialized) {
      return;
    }

    final result = await safe((db) async {
      final stmt = await db.select(db.versions).get();
      return stmt
          .map((e) => (UserId(e.userId), _SessionDataDb.fromDb(e)))
          .toList();
    }, exclusive: false);

    for (var e in result ?? <(UserId, SessionData)>[]) {
      data[e.$1] = e.$2;
    }

    _initialized = true;
  });
}
