react-native: Newly initialized react native project has flow errors

Description

The long and short of it is, I’m getting flow errors on brand new projects created with the react native cli (version 2.0.1). Do I have a weird version mismatch or something?

Reproduction

drew.wyatt$ react-native --version
react-native-cli: 2.0.1
react-native: 0.39.2

drew.wyatt$ flow version
Flow, a static type checker for JavaScript, version 0.35.0

Solution

Right now I’m just not using flow and ignoring the issues. I’ve tried switching some versions around but keep coming up empty handed.

Additional Information

React Native CLI version: 2.0.1
React Native version: 0.39.2
Flow version: 0.35.0
Platform: Development Environment
Operating System: macOS Sierra Version 10.12.2

I’m having issues using numerous flow versions with RN as well. Hundreds of errors in node_modules/react-native each time with numerous different versions of flow including the latest.

I will probably just rely on PropTypes for similar effect in the meantime, but it’s pretty bad practice to even mention a tool like Flow (see https://facebook.github.io/react/docs/typechecking-with-proptypes.html) when there are so many errors out of the box in the core project and no clear way to circumvent them.

This is not the first ticket of this nature and past tickets have even claimed that upgrading to RN 0.42 will fix the issue, but I have not found that to be true as I am on 0.42 and have tried several things including using the .flowconfig in the RN project itself and the Flow version listed therein.

Perhaps I’m misunderstanding something about Flow, but if not, please either treat this issue more seriously (maybe add a flow run to your CI?) or stop promoting Flow until your own project passes or at least suppresses your own errors. This has been a waste of time for everyone who has come across the string of tickets raising this issue.

Still having this issue after creating new project with react-nativi init helloworld

$ flow version
Flow, a static type checker for JavaScript, version 0.59.0
$ react-native --version      
react-native-cli: 2.0.1
react-native: 0.50.4

Updated the .flowconfig to use the correct flow version I have installed.

Running flow results in 22 errors:

I was having the same problem.

But then I realised that on a fresh react-native install, the .flowconfig file stated a specific version at the end of the file (in my case ^0.38.0). So then I installed flow-bin with that same version.

Previously I was trying the oposite direction (install latest flow-bin version and then updating that version on the .flowconfig file).

Found 30 errors

drewwyatt on Feb 27, 2017

flow: 0.37.4, react: 15.4.2, react-native: 0.41.2

Flow has been completely broken for me since around RN 0.39.0. Not only do I get lots of errors stemming from node_modules/ but it no longer reports anything for my actual project.

techrah on Feb 21, 2017

i also getting this problem because i have in folder up node_modules when i remove node_modules it pass

ButuzGOL on May 8, 2017

It seems like react-native should target a specific flow version rather than a ^ version. At least use ~. Minor flow versions have breaking changes all of the time, so it doesn’t make sense to allow the latest minor version to install when it hasn’t been tested.
