maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. int id,
    2. String topic,
    3. String method,
    4. String chainId,
    5. dynamic params,
    6. VerifyContext verifyContext,
    7. TransportType transportType,
    )?, {
  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( int id,  String topic,  String method,  String chainId,  dynamic params,  VerifyContext verifyContext,  TransportType transportType)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _SessionRequest() when $default != null:
return $default(_that.id,_that.topic,_that.method,_that.chainId,_that.params,_that.verifyContext,_that.transportType);case _:
  return orElse();

}
}
