whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String key,
    2. SettingUpsertOptionScope scope,
    3. Map<String, dynamic> value,
    4. String? description,
    5. SettingUpsertOptionManagerRole? managerRole,
    6. 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 key, @SettingUpsertOptionScopeConverter()  SettingUpsertOptionScope scope,  Map<String, dynamic> value,  String? description, @SettingUpsertOptionManagerRoleConverter()  SettingUpsertOptionManagerRole? managerRole,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _SettingUpsertOptionInput() when $default != null:
return $default(_that.key,_that.scope,_that.value,_that.description,_that.managerRole,_that.$unknown);case _:
  return null;

}
