send<T> method

Future<T?> send<T>(Future<(T?, Object?, String?)> call, VoidCallback? reload)

Awaits a service call's (ok, error, exception) result: on success toasts and runs reload, otherwise toasts the error. Returns the ok response (on create its result is the new id), or null when it failed.

Implementation

Future<T?> send<T>(Future<(T?, Object?, String?)> call, VoidCallback? reload) async {
  final (T? ok, Object? error, String? exception) = await call;
  if (ok == null) {
    final String? errorMessage = switch (error) {
      final UEmptyResponse e => e.message,
      final UResponse<dynamic> e => e.message,
      _ => null,
    };
    UToast.error(message: errorMessage.nullIfEmpty() ?? exception.nullIfEmpty() ?? U.s.errorSubmittingForm);
    return null;
  }
  final String? okMessage = switch (ok) {
    final UEmptyResponse r => r.message,
    final UResponse<dynamic> r => r.message,
    _ => null,
  };
  UToast.snackBar(message: okMessage.nullIfEmpty() ?? U.s.submitted);
  reload?.call();
  return ok;
}
