when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. Uint8List publicKey,
    2. SecureKey secretKey
    )
)

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( Uint8List publicKey,  SecureKey secretKey)  $default,) {final _that = this;
switch (_that) {
case _KeyPair():
return $default(_that.publicKey,_that.secretKey);}
}
