@override Future<List<DatabaseData>> removeOversized(int maxCacheSize)

Remove data from storage until the storage file size is less than maxCacheSize.

Implementation

@override
Future<List<DatabaseData>> removeOversized(int maxCacheSize) async {
  final removedData = <DatabaseData>[];
  final db = await _getDb();
  final file = File(db.path);

  while (file.lengthSync() > maxCacheSize) {
    final maps = await db.query(
      _cacheTable,
      orderBy: '$_lastUsedAt, $_useCount',
      limit: 1,
    );
    if (maps.isEmpty) break;

    final dbData = DatabaseData.fromJson(maps.first);
    removedData.add(dbData);
    await remove(
      dbData.key,
      dbData.queryParams,
      rebuildDb: true,
    );
  }

  return removedData;
