whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String $type,
    2. String code,
    3. int available,
    4. bool disabled,
    5. String forAccount,
    6. String createdBy,
    7. DateTime createdAt,
    8. List<InviteCodeUse> uses,
    9. Map<String, dynamic>? $unknown,
    )?
)

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 $type,  String code,  int available,  bool disabled,  String forAccount,  String createdBy,  DateTime createdAt, @InviteCodeUseConverter()  List<InviteCodeUse> uses,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _InviteCode() when $default != null:
return $default(_that.$type,_that.code,_that.available,_that.disabled,_that.forAccount,_that.createdBy,_that.createdAt,_that.uses,_that.$unknown);case _:
  return null;

}
