maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. EncryptionAlgorithm algorithm,
    2. PublicKey sourcePublicKey,
    3. PublicKey recipientPublicKey,
    4. String data,
    5. String nonce,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( EncryptionAlgorithm algorithm,  PublicKey sourcePublicKey,  PublicKey recipientPublicKey,  String data,  String nonce)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _EncryptedData() when $default != null:
return $default(_that.algorithm,_that.sourcePublicKey,_that.recipientPublicKey,_that.data,_that.nonce);case _:
  return orElse();

}
}
