whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String id,
    2. @JsonKey.new(name: 'created') String created,
    3. TokenType type,
    4. bool livemode,
    5. BankAccount? bankAccount,
    6. CardData? card,
    )?
)

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, @JsonKey(name: 'created')  String created,  TokenType type,  bool livemode,  BankAccount? bankAccount,  CardData? card)?  $default,) {final _that = this;
switch (_that) {
case _TokenData() when $default != null:
return $default(_that.id,_that.created,_that.type,_that.livemode,_that.bankAccount,_that.card);case _:
  return null;

}
}
