operator [] method

  1. @override
MariaDbColumn operator [](
  1. Object? key
)
override

The value for the given key, or null if key is not in the map.

Some maps allow null as a value. For those maps, a lookup using this operator cannot distinguish between a key not being in the map, and the key being there with a null value. Methods like containsKey or putIfAbsent can be used if the distinction is important.

Implementation

@override
MariaDbColumn operator [](Object? key) {
  return _columns.firstWhere(
    (element) => element.name == key,
    orElse: () => throw Exception(
      "This mariadb table `$name` has no column "
      "with the name `$key`",
    ),
  );
}
