maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String type, String? description, @JsonKey.new(name: 'default') int? defaultValue, int? minimum, int? maximum, @JsonKey.new(name: 'enum') List<int>? enumValues, @JsonKey.new(name: 'const') int? constValue,)?, { required TResult orElse(), })

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( String type,  String? description, @JsonKey(name: 'default')  int? defaultValue,  int? minimum,  int? maximum, @JsonKey(name: 'enum')  List<int>? enumValues, @JsonKey(name: 'const')  int? constValue)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _LexInteger() when $default != null:
return $default(_that.type,_that.description,_that.defaultValue,_that.minimum,_that.maximum,_that.enumValues,_that.constValue);case _:
  return orElse();

}
