@shilman, @ndelangen could you remove now bot from RN repo?

[ndelangen]

I removed now.sh

[dannyhw]

rebased this with master to reevaluate the status of this pr

[dannyhw]

after looking through old issues it seems like for this to work storiesOf should be called once per file see #31.

[ndelangen]

yes, storiesOf should be once per file, that's how it's also defined for CSF

[dannyhw]

this change relies on storybookjs/storybook#9868 and so we would need this change for 5.3.x in order to fix this for this version of react native storybook

[dannyhw]

storybookjs/storybook#9868 has now been released for version 5.3 with the 5.3.21 release 🥳. Should now be able to give this one another go.

[dannyhw]

I got a bit stuck with this because I was finding it really hard to reproduce in the issue in the example project. Thinking this one might be delayed for the next release.

[mohsinulhaq]

@Gongreg any issues in this? would be really helpful if this was fixed :)

[dannyhw]

@mohsinulhaq I had issues with testing this change which makes it hard to tell if these changes work or not otherwise I would have merged it already.

Also there will be significant changes to this part of the code to support 6.0 so it might be easier fixed in 6.0.

[mohsinulhaq]

@dannyhw No problem. Thanks!

[dannyhw]

Will be fixed as part of 6.0 CSF support etc.
