whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String? id,
    2. bool read,
    3. bool write,
    4. bool manage,
    5. String? objectId,
    6. String? userId,
    7. AccessModule module,
    )?
)

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,  bool read,  bool write,  bool manage,  String? objectId,  String? userId, @JsonKey(unknownEnumValue: AccessModule.unknown)  AccessModule module)?  $default,) {final _that = this;
switch (_that) {
case _AccessInput() when $default != null:
return $default(_that.id,_that.read,_that.write,_that.manage,_that.objectId,_that.userId,_that.module);case _:
  return null;

}
}
