Auto link issue

[lehang123]

When I follow the instruction by the react-navigation website : https://reactnavigation.org/docs/en/getting-started.html.

react-native link react-native-gesture-handler

and then change the MainActivity.java like it asks.

Then run react-native run-android, and error pop up :
error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:

react-native-gesture-handler (to unlink run: "react-native unlink react-native-gesture-handler")
This is likely happening when upgrading React Native from below 0.60 to 0.60 or above. Going forward, you can unlink this dependency via "react-native unlink " and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.

However, when I follow the instruction, to unlink the library
use : react-native unlink react-native-gesture-handler

The app successfully built, but now it pops up another error in the app :
null is not an object (evaluating 'rngesturehandlermodule.direction')
I tried a lot of solution in a lot of websites, like
#494
https://stackoverflow.com/questions/52861437/undefined-is-not-an-object-evaluating-rngesturehandlermodule-state

non of them is working for me

Read this https://facebook.github.io/react-native/blog/2019/07/03/version-60#native-modules-are-now-autolinked

You don't need to run react-native link anymore in most scenario.

I un-linked it, but then another error pop up :

Can you run react-native info and edit your issue to include these results under the React Native version: section?

If you believe this information is irrelevant to the reported issue, you may write `[skip envinfo]` alongside an explanation in your Environment: section.

React Native Gesture Handler is not compatible with autolinking yet. Please send this issue over there to them. The error says explicitly:

If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.

So please do so, here's the link to the repo: https://github.com/kmagiera/react-native-gesture-handler

So if it isn't compatible does that mean it can't be used?

[thymikee]

@smooJitter it is compatible and can be used with newest RN. If linked manually, it needs to be unlinked with yarn react-native unlink react-native-gesture-handler. If it's not linked yet, install it and follow https://kmagiera.github.io/react-native-gesture-handler/docs/getting-started.html#android on Android (this is the only change that needs to be done manually for this package), then run cd ios && pod install to make it work on iOS.

Also make sure to update the @react-native-community/cli to the latest version.
