  2. {bool verbose = false}
)

Execute a query

Implementation

Future<List<Map<String, dynamic>>> query(String q,
    {bool verbose = false}) async {
  /// [q] the query to execute
  try {
    if (!_isReady) {
      throw DatabaseNotReady();
    }
    final timer = Stopwatch()..start();
    List<Map<String, dynamic>> res;
    await _db.transaction((txn) async {
      res = await txn.rawQuery(q);
    }).catchError((dynamic e) =>
        throw RawQueryException("Can not execute query $q $e"));
    timer.stop();
    if (verbose) {
      final msg = "$q in ${timer.elapsedMilliseconds} ms";
      print(msg);
    }
    return res;
  } catch (e) {
    rethrow;
  }
