[mark2685]

Production Error

Issue occurs when trying to use zustand/middleware/immer with zustand-computed:

Argument of type 'StateCreator<Store & ComputedStore, [], [["zustand/devtools", never], ...[keyof StoreMutators<unknown, unknown>, unknown][]]>' is not assignable to parameter of type 'StateCreator<Store, [], [["zustand/devtools", never], ...[keyof StoreMutators<unknown, unknown>, unknown][]]>'.
Types of parameters 'getState' and 'getState' are incompatible.
Type 'Store' is not assignable to type 'Store & ComputedStore'.
Property 'countSq' is missing in type 'Store' but required in type 'ComputedStore'.ts(2345)
App.tsx(15, 3): 'countSq' is declared here.

Error is also reproduced in example/src/App.tsx.

Steps to resolve:

Deleting the yarn.lock file and generating a new file via yarn install will resolve the issue, but I'm not sure exactly why it was occurring with the lock file.

While testing, I noticed some zustand version inconsistencies and an issue with the example test. so updated those as well.

Note: zustand upgrade to 4.3.8 is not required to fix, this could be fixed while using 4.3.2 with the steps above. But seemed safe to include those as part of this update.
