Unable to run automated tests as this library has opted out of null safety. Any plans to implement null safety? May I give it a try and raise a PR for this?

Error: A library can't opt out of null safety by default, when using sound
null safety.
// @Dart = 2.3

Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

• package:esp_softap_provisioning
