get method

@override Map<String, dynamic>? get(String key)

Gets the value of the specified key, if it hasn't been cached yet, it caches it. If the key doesn't exist it throws an error.

Implementation

@override
Map<String, dynamic>? get(String key) {
  _checkInitialized();

  final String keyWithPrefix = _addPrefix(key);
  if (_map.containsKey(keyWithPrefix)) {
    return _map[keyWithPrefix];
  }

  Map<String, dynamic>? value = _getPref(keyWithPrefix);
  if (value != null) {
    _map[keyWithPrefix] = value;
  }
  return value;
}
