whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String repo,
    2. String collection,
    3. String rkey,
    4. bool? validate,
    5. Map<String, dynamic> record,
    6. String? swapRecord,
    7. String? swapCommit,
    8. 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 repo,  String collection,  String rkey,  bool? validate,  Map<String, dynamic> record,  String? swapRecord,  String? swapCommit,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _RepoPutRecordInput() when $default != null:
return $default(_that.repo,_that.collection,_that.rkey,_that.validate,_that.record,_that.swapRecord,_that.swapCommit,_that.$unknown);case _:
  return null;

}
