Cannot download tracked memory leaks

[Thioby]

On version 8.0.3 you are not able to download tracked memory leaks.

The problem is here: (_protocol.dart)

As you can see there is 7 types of envelopes, but type that is looked for is Future<Leaks> . Envelope is not found, null from map and then is forced to be not a null, that's why is crashing.

Class class ResponseFromApp<T extends Object> allows passing any object as message. So in case of leaks, as a message is passed Future instead of Leaks itself.

Solution:

In file _registration.dart at line 50 add await before creating ResponseFromApp object

      if (request is RequestForLeakDetails) {
        return ResponseFromApp(await theLeakProvider.collectLeaks())
            .toServiceResponse();
      }

Thank you for reporting. This should be addressed.
