fetchOrNull function

Future<String?> fetchOrNull(
  1. Future<String?> fetch()
)

What fetch returns, or null when it throws: an ObservANT camera that cannot be reached answers nothing.

Implementation

Future<String?> fetchOrNull(Future<String?> Function() fetch) async {
  try {
    return await fetch();
  } on Object {
    return null;
  }
}
