Hello @xiaoyongchen

Thank your for your interest in this project.

However, your issue is a usage/support question, and the issue tracker is reserved exclusively for bug reports and feature requests (as outlined in our Contributing Guide).

We encourage you to ask it on Discord chat or Stack Overflow or on our and are happy to help you out there.

computed's needs to be annotated here as aotherwise, the type of state is circular and therfore not inferrable for TS.
