add version to .flowconfig

[benadamstyles]

The consequence of this is that flow will not run in this project unless you have [email protected] installed. One solution to this is adding flow-bin to this package's devDependencies.

I'm not 100% sure what will happen if someone's react native project is using a different version of flow. Maybe we need to think further about the consequences of this PR. One alternative would be to install [email protected] and not merge this PR... then contributors to this package would just use the local flow-bin to dev against. What do you think?

I'd be inclined to follow what has been done in the main RN project and add flow-bin to RN-Firebase's devDependencies. At least you ensuring that when developing with the library, everybody is using the same version of Flow and working to a consistent standard?

[benadamstyles]

Yep, sounds good, although the main RN project also has the [version] entry in .flowconfig. I've tried to look for advice for package authors on this subject but no luck. I think I'll close this PR and submit a new one with the flow-bin dependency (matching the [version] specified in the latest stable RN release. Sound ok?

[chrisbianca]

I don't think there's any harm to having it specified in .flowconfig as long as they match.. I'd just modify this PR and add the flow-bin dev dependency as well

[benadamstyles]

Ok 👍
