Flutter autocomplete suggestions not working

My autocomplete suggestions just stopped working. As an example, none of the widgets show inside suggestions window when I start typing, here is the screenshot when I want to add BoxDecoration:

Steps to Reproduce

I’m not exactly sure how this happened, but the issue started when I ran android emulator inside tool window ( I ran it as a separate window before.)

I created this project few days ago and everything was working fine until now.

Edit: I tried to fix it with invalidate caches and restart, flutter clean, without emulator running, running emulator outside tool window again. None of those things fixed the problem.

This just started happening to me after Flutter 3.0, suggestions like setState and overrides such as initState and didChangeDependecies aren’t working anymore. May we reopen this please?

Omg, finally I find out someone who has the same issue with a setState. I’m new to programming (and learning Flutter) and can’t realize the reason for such thing. So, this is just a glitch of 3.0 and will be fixed? 😉
