how to invalidate all cache?

[peterweb2005]

thanks

case:
my app need always update (may be in interval), as other users may updated their created content
so, i need to create a timer hook, and on event invalidate all cache,

so, how to invalidate all cache?

actually, my current situation, every request has a time argument,
when i update the time argument (with provider then notify), the content with attached provider will refresh

thanks

Invalidating "all" the cache is not something you truly want to do.

If you want to update a provider every few seconds, you can do:

FutureProvider((ref) {
  final timer = Timer(duration, (_) => ref.invalidateSelf());
  ref.onDispose(timer.cancel);
  
  return fetchWhatever()
});

can it invalidate without refresh?

my currently protential solution, update all timestamps,
as all my providers (of diff data types) family parameterized with timestamp argument
