map<TResult extends Object?> method

  1. @optionalTypeArgs
TResult map<TResult extends Object?>({
  1. required TResult getLink(
    1. _GetLink value
    ),
  2. required TResult getInvoiceStatus(
    1. _GetInvoiceStatus value
    ),
})

A switch-like method, using callbacks.

Callbacks receives the raw object, upcasted. It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult map<TResult extends Object?>({required TResult Function( _GetLink value)  getLink,required TResult Function( _GetInvoiceStatus value)  getInvoiceStatus,}){
final _that = this;
switch (_that) {
case _GetLink():
return getLink(_that);case _GetInvoiceStatus():
return getInvoiceStatus(_that);case _:
  throw StateError('Unexpected subclass');

}
}
