[firebase_database] Add a getter in Query which return full path with query's parameters

[XenoMACHINE]

Description
I'm always frustrated when i want to manage queries listeners.

Example
I want many queries listeners like this
final query1 = FirebaseDatabase.instance.reference().child("users").orderByChild("uid").equalTo(UID1); final query2 = FirebaseDatabase.instance.reference().child("users").orderByChild("uid").equalTo(UID2);

I launch and store listeners like this :

Map<String, StreamSubscription<Event>> launchedQueries = Map(); launchedQueries[query.path] = query1.onValue.listen((event) => onData(event.snapshot)); launchedQueries[query.path] = query2.onValue.listen((event) => onData(event.snapshot));

The problem is that both queries.path return "users". But they are different (parameters are not same, UID1 / UID2 ).
I do that in order to manage properly my listeners, to have one listener for each query and to cancel a listener easily with a given query.

Solution
Add a getter in Query like
String get fullPath => '$path/${_parameters.entries.map((e) => '${e.key}/${e.value}').join('/')}';

Or just set _parameters to public.
