[FIXED] How can I access state of another slice in redux with redux-toolkit?

Issue

In my Redux store I have multiple slices and I would like to access the lang state of the settingsSlice inside the speciesSlice.

Here is a code sample of my slices:

const settingsSlice = createSlice({
  name: 'settings',
  initialState: { lang: 'en', theme: 'dark' },
  reducers: {
    ...
  },
});

const speciesSlice = createSlice({
  name: 'species',
  initialState: data[`vds-list-${HERE I WANT TO USE THE "lang" STATE OF THE SETTINGSSLICE}`],
  reducers: {
    ...
  },
});

Thus far I haven't found a solution so maybe it's just not possible?

I could just use one slice with all of the state inside of there, but I'd really like to separate different parts of the state in different slices.

Solution

Reducers, by definition, only have access to the section of state that they own. So, if I have {users: usersReducer, posts: postsReducer}, the usersReducer has no access to the posts state slice at all.

See the Redux FAQ entry on "how can I share state between reducers?" for more details.
