map<TResult extends Object?> method

  1. @optionalTypeArgs
TResult map<TResult extends Object?>({
  1. required TResult item(
    1. UnitItem value
    ),
  2. required TResult ssCC(
    1. UnitSSCC value
    ),
  3. required TResult ph(
    1. UnitPH 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( UnitItem value)  item,required TResult Function( UnitSSCC value)  ssCC,required TResult Function( UnitPH value)  ph,}){
final _that = this;
switch (_that) {
case UnitItem():
return item(_that);case UnitSSCC():
return ssCC(_that);case UnitPH():
return ph(_that);}
}
