when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<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,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( int id,  String topic,  String method,  String chainId,  dynamic params,  VerifyContext verifyContext,  TransportType transportType)  $default,) {final _that = this;
switch (_that) {
case _SessionRequest():
return $default(_that.id,_that.topic,_that.method,_that.chainId,_that.params,_that.verifyContext,_that.transportType);}
}
