map<TResult extends Object?> method

  1. @optionalTypeArgs
TResult map<TResult extends Object?>({
  1. required TResult knownValue(
    1. ReportViewStatusKnownValue value
    ),
  2. required TResult unknown(
    1. ReportViewStatusUnknown 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( ReportViewStatusKnownValue value)  knownValue,required TResult Function( ReportViewStatusUnknown value)  unknown,}){
final _that = this;
switch (_that) {
case ReportViewStatusKnownValue():
return knownValue(_that);case ReportViewStatusUnknown():
return unknown(_that);case _:
  throw StateError('Unexpected subclass');

}
}
