refresh<T> abstract method

  1. @useResult
T refresh<T>(
  1. Refreshable<T> provider

Forces a provider to re-evaluate its state immediately, and return the created value.


final newValue = ref.refresh(provider);

is strictly identical to doing:

final newValue =;

If you do not care about the return value of refresh, use invalidate instead. Doing so has the benefit of:

  • making the invalidation logic more resilient by avoiding multiple refreshes at once.
  • possibly avoids recomputing a provider if it isn't needed immediately.

This method is useful for features like "pull to refresh" or "retry on error", to restart a specific provider.


T refresh<T>(Refreshable<T> provider);
