Implementation

Dropdown({
  required Iterable<String> options,
  Object? value,
  this.hint,
  this.label,
  Object? onChanged,
  String? name,
  Object? visible,
}) : options = List.unmodifiable(options),
     value = normalizeNullableExpression(value),
     onChanged = normalizeActionSequence(
       onChanged,
       parameterName: 'onChanged',
     ),
     super(name: name, visible: _normalizeVisibility(visible));
