mapOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? mapOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. _P24PaymentMethodDetailsWithBilling value
    )?, {
  2. TResult? id(
    1. _IdP24PaymentMethodDetailsIdOnly value
    )?,
})

A variant of map that fallback to returning null.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? mapOrNull<TResult extends Object?>(TResult? Function( _P24PaymentMethodDetailsWithBilling value)?  $default,{TResult? Function( _IdP24PaymentMethodDetailsIdOnly value)?  id,}){
final _that = this;
switch (_that) {
case _IdP24PaymentMethodDetailsIdOnly() when id != null:
return id(_that);case _P24PaymentMethodDetailsWithBilling() when $default != null:
return $default(_that);case _:
  return null;

}
