We updated flow to 0.34 and 0.35 in RN 0.39.0-rc.0. You can update to the RC version and it should fix it.

Ok, thanks for testing that out
@jeffmo Any idea how to fix this error?
janicduplessis
on 27 Nov 2016
After this plaguing me for a while, I found the fix: update your suppress_comment lines in .flowconfig.
i.e. when upgrading from Flow 0.36.0 to 0.37.0, this commit shows you should update the regex from 0-6 to 0-7. This is extreeeeemely non-obvious, though, and should probably be addressed in the future in a better way. (I updated our regex to be [3-9][0-9] so hopefully it won't be an issue for us again until 1.x.x. I'm not sure if this is a Bad Ideaâ„¢ though, but it unblocks us.)
Version support:
RN 0.38.0 works with Flow 0.33.0.
RN 0.39.2 works with Flow 0.35.0.
RN 0.40.0-rc.4 works with Flow 0.36.0.
RN HEAD (currently f625437ee9f566ecdc65b8a446f22039eaaa88ad, and I'm assuming rc5 onward) works with Flow 0.37.0.
Take your pick! :)

@notjosh I'm on RN 0.41 and Flow 0.37.4. I have 469 errors, most of them from node_modules/. What suppress_comment can I use to suppress these errors? My current config for this is:
suppress_comment=\\(.\\|\n\\)*\\$FlowFixMe\\($\\|[^(]\\|(\\(>=0\\.\\(3[0-7]\\|[1-2][0-9]\\|[0-9]\\).[0-9]\\)? *\\(site=[a-z,_]*react_native[a-z,_]*\\)?)\\)
suppress_comment=\\(.\\|\n\\)*\\$FlowIssue\\((\\(>=0\\.\\(3[0-7]\\|1[0-9]\\|[1-2][0-9]\\).[0-9]\\)? *\\(site=[a-z,_]*react_native[a-z,_]*\\)?)\\)?:? #[0-9]+
suppress_comment=\\(.\\|\n\\)*\\$FlowFixedInNextDeploy
Thanks in advance to anyone who can help. It's almost impossible to use Flow for type checking as is.

My issue turned out to be an entry I added to [options]:
module.file_ext=.ios.js
which was to suppress flow errors caused when using such extensions. Removing this fixed my plethora of errors and I don't see the error I was getting before that made me add that option in the first place so maybe flow now supports .ios.js and .android.js extensions -- though I'm not sure.

I use RN 0.41.2 and Flow 0.41.0, and encounter the same issues. It shows hundreds of errors from flow type check. Most of them are in the node_modules/react-native/Libraries/Components/ folder.
Is there any way to quick fix this (workaround)?

I think the only way to fix this is to upgrade to 0.42. Really sorry about the inconvenience- we are going to be careful with flow errors from here on

I still need to ignore some sources to suppress warnings from node_modules in .flowconfig with RN 0.42:
[ignore]
; https://gist.github.com/xjamundx/ffafa67925db6d7ffc4c86a7fb2bcb45
.*/node_modules/.*[^e]\.json$
.*/node_modules/.*\(lib\|test\).*\.json$
; Temporally ignore the following node modules
.*/node_modules/react-native-experimental-navigation/.*
.*/node_modules/react-native/.*
Still seeing this one in RN 42 when analyzing the react-native-linear-gradient package:
node_modules/react-native/Libraries/Network/NetInfo.js:247
247: listener
^^^^^^^^ undefined. This type is incompatible with the expected param type of
197: handler: Function
^^^^^^^^ function type
