whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. AtUri anchor,
    2. bool above,
    3. int below,
    4. int branchingFactor,
    5. bool prioritizeFollowedUsers,
    6. UnspeccedGetPostThreadV2Sort? sort,
    7. 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(@AtUriConverter()  AtUri anchor,  bool above,  int below,  int branchingFactor,  bool prioritizeFollowedUsers, @UnspeccedGetPostThreadV2SortConverter()  UnspeccedGetPostThreadV2Sort? sort,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _UnspeccedGetPostThreadV2Input() when $default != null:
return $default(_that.anchor,_that.above,_that.below,_that.branchingFactor,_that.prioritizeFollowedUsers,_that.sort,_that.$unknown);case _:
  return null;

}
