Yes that looks promising but how would you handle a TTL greater than the runtime of the app?
It would need to be persisted and checked when the app is started again.

This is a very good idea. I don't know if it is possible but I'll think about how to implement this.
from hive.
I've tinkered with something like this :
class Ephemere {
final Duration defaultDuration;
final Map<Object, dynamic> _cache;
Ephemere(this.defaultDuration) : _cache = Map();
dynamic get(Object key, Function defaultValue) {
final rs = _cache[key] ?? defaultValue();
return rs;
}
Future put(Object key, value, {Duration duration}) {
Completer completer = Completer();
_cache.putIfAbsent(key, () => value);
Future.delayed(duration ?? defaultDuration, () {
_cache.remove(key);
completer.complete(value);
});
return completer.future;
}
}

Correct, Also I'm not sure this approach is the best when you have a huge numbers of keys ...
If you have a hash you can have an external manager with timestamp, seems more efficient.
Completers would resume on the diff time now and previously calculated expiration timestamps.

I agree...

Could you please explain that? I don't understand what you mean exactly.

I'm going to close this for now. I think a external solution would be easier to implement...
