[Documentation]: Update RN documentation around AsyncStorage

[jsjoeio]

Is your feature request related to a problem? Please describe.
I'm new user of Storybook. We're using it on a React Native project. I've upgraded to the @next version to remove a warning about AsyncStorage per the recommendation here: https://github.com/storybookjs/storybook/issues/6078#issuecomment-549834805

Now, I see a new warning, which suggests I follow the MIGRATION.md guide, which takes me here: https://github.com/storybookjs/storybook/blob/next/MIGRATION.md#react-native-async-storage

I see the solutions (thank you for those!), but now I'm wondering if I'm choosing the right one.

Use null to disable Async Storage completely.

Also wondering, "What are the benefits of using AsyncStorage within Storybook? It doesn't tell me, and I am struggling to find any documentation around this.

The only relevant info I've found is the PR which adds in the new change:

• React-native: Require user-provided async storage storybook#7801

Describe the solution you'd like
I'd love to see some documentation around why, I as a developer, should use AsyncStorage with React Native Storybook.

Describe alternatives you've considered
I could just leave it as is and not say anything, but I figure I'm not the only one who may stumble into this scenario. And I like what Storybook provides for us, so I'd like to give back.

Are you able to assist bring the feature to reality?
Yes, I'd be happy to update the docs or the MIGRATION.md.

Hey @jsjoeio .
Sorry for missing the issue.
The benefit of using Async Storage is that when yuo refresh your app, storybook will open your last visited story.

If you can find a place to put this information somewhere in the documentation, the PR is very welcome :)

[jsjoeio]

Awesome sauce! Thanks for following up on this. I'll find a place an open a PR :)

@Gongreg after adding asyncStorage I'm not seeing the app return to my last visited story on refresh, is there any other config required for this to work?

[Gongreg]

Hey @dannyhw, how did you enable it? What did you pass to asyncStorage?

[dannyhw]

import {AsyncStorage} from '@react-native-community/async-storage';
const StorybookUIRoot = getStorybookUI({
  asyncStorage: AsyncStorage,
});

However I also tried with require('@react-native-community/async-storage').AsyncStorage

[Gongreg]

Did you fully link it? https://github.com/react-native-community/async-storage There is information about linking it.

[dannyhw]

😅 I just changed import {AsyncStorage} to import AsyncStorage and it started working, now I feel silly haha. I immediately saw this from their example. Thanks for the quick response though!

[Gongreg]

glad that it works :)
