e10_refresh_cache_v3

Feature:

No matter what user entered, always return a random value between 1 and 100. And this value is based on cache that won’t change while user is typing. However, we want to provide a way to refresh the value. User can type “!~”, then the value will be refreshed after 1 seconds, and the “!~” will be removed automatically. During the waiting, it will show a helper text to tell user to wait.

Difficulty: Medium

Dependencies: NA
