map<TResult extends Object?> method

  1. @optionalTypeArgs
TResult map<TResult extends Object?>({
  1. required TResult context(
    1. _ValueBuilderContext<T> value
    ),
  2. required TResult ref(
    1. _ValueBuilderRef<T> value
    ),
  3. required TResult value(
    1. _ValueBuilderValue<T> 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( _ValueBuilderContext<T> value)  context,required TResult Function( _ValueBuilderRef<T> value)  ref,required TResult Function( _ValueBuilderValue<T> value)  value,}){
final _that = this;
switch (_that) {
case _ValueBuilderContext():
return context(_that);case _ValueBuilderRef():
return ref(_that);case _ValueBuilderValue():
return value(_that);}
}
