whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String? id,
    2. String? name,
    3. String? description,
    4. BrickhouseBillingPeriod? billingPeriod,
    5. int tierLevel,
    6. Map<String, dynamic>? customProperties,
    )?
)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( String? id,  String? name,  String? description,  BrickhouseBillingPeriod? billingPeriod,  int tierLevel,  Map<String, dynamic>? customProperties)?  $default,) {final _that = this;
switch (_that) {
case _BHSPermissionTierInput() when $default != null:
return $default(_that.id,_that.name,_that.description,_that.billingPeriod,_that.tierLevel,_that.customProperties);case _:
  return null;

}
}
