whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String? apiKey,
    2. String? appId,
    3. String? projectId,
    4. String? messagingSenderId,
    5. String? storageBucket,
    )?
)

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? apiKey,  String? appId,  String? projectId,  String? messagingSenderId,  String? storageBucket)?  $default,) {final _that = this;
switch (_that) {
case _PushSecretsInput() when $default != null:
return $default(_that.apiKey,_that.appId,_that.projectId,_that.messagingSenderId,_that.storageBucket);case _:
  return null;

}
}
