do you met the problem that idea cannot auto import getValue of

by mutableStateOf

Known issue AFAIK. It's been mention a few times in here and #compose You should be able to add the import manually OR if you write out the mutableStateOf type explicitly (I think) then the importing will actually work. I've never hit this issue though so I could be saying the wrong thing. Search those two channels though and you'll find the right answer.

okay, thank you. I'll check it later

It comes up every few days, so it should be somehwat recent. I think I saw it in the past week. 😄
