maybeMap<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeMap<TResult extends Object?>(
  1. TResult $default(
    1. _CardPaymentMethodDefault value
    )?, {
  2. TResult id(
    1. _CardPaymentMethodRef value
    )?,
  3. TResult token(
    1. _CardPaymentMethodDetailsToken value
    )?,
  4. required TResult orElse(),
})

A variant of map that fallback to returning orElse.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult maybeMap<TResult extends Object?>(TResult Function( _CardPaymentMethodDefault value)?  $default,{TResult Function( _CardPaymentMethodRef value)?  id,TResult Function( _CardPaymentMethodDetailsToken value)?  token,required TResult orElse(),}){
final _that = this;
switch (_that) {
case _CardPaymentMethodRef() when id != null:
return id(_that);case _CardPaymentMethodDefault() when $default != null:
return $default(_that);case _CardPaymentMethodDetailsToken() when token != null:
return token(_that);case _:
  return orElse();

}
