maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String hash,
    2. Address? src,
    3. Address? dst,
    4. BigInt value,
    5. bool bounce,
    6. bool bounced,
    7. String? body,
    8. String? bodyHash,
    )?, {
  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( String hash,  Address? src,  Address? dst,  BigInt value,  bool bounce,  bool bounced,  String? body,  String? bodyHash)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _Message() when $default != null:
return $default(_that.hash,_that.src,_that.dst,_that.value,_that.bounce,_that.bounced,_that.body,_that.bodyHash);case _:
  return orElse();

}
}
