when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. @JsonKey.new(name: 'id') String? id,
    2. @JsonKey.new(name: 'name') String? name,
    3. @JsonKey.new(name: 'is_active') bool? isActive,
    4. @JsonKey.new(name: 'number') String? number,
    5. @JsonKey.new(name: 'tag') String? tag,
    6. @JsonKey.new(name: 'description') String? description,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function(@JsonKey(name: 'id')  String? id, @JsonKey(name: 'name')  String? name, @JsonKey(name: 'is_active')  bool? isActive, @JsonKey(name: 'number')  String? number, @JsonKey(name: 'tag')  String? tag, @JsonKey(name: 'description')  String? description)  $default,) {final _that = this;
switch (_that) {
case _PayablesAccount():
return $default(_that.id,_that.name,_that.isActive,_that.number,_that.tag,_that.description);case _:
  throw StateError('Unexpected subclass');

}
