assertValid method

@override void assertValid()

Runs a dev-mode assertion that the definition is valid.

When assertions are enabled, throws StateError. Otherwise does nothing.

Implementation

@override
void assertValid() {
  if (!isDevMode) {
    return;
  }
  if (redirectTo == path) {
    throw StateError('Cannot redirect from `redirectTo` to `path');
  }
  var pathParameters = parameters;
  var unknownRedirectToParameters = _redirectToParameters.where(
      (redirectToParameter) => !pathParameters.contains(redirectToParameter));
  if (unknownRedirectToParameters.isNotEmpty) {
    throw StateError('Parameters in `redirectTo` are not in `path`: '
        '$unknownRedirectToParameters');
  }
}
