Invariant Violation: View config getter callback for component BVLinearGradient must be a function (received undefined).

I am trying to setup this lib for iOS

I am getting this error log in metro console

Invariant Violation: View config getter callback for component BVLinearGradient must be a function (received undefined)

This error is located at:
    in BVLinearGradient (at react-native-linear-gradient/index.ios.js:54)
    in LinearGradient (at WelcomeView.react.tsx:90) 

i have tried bunch of stuff like

• pod install
• npx pod-install
• react-native link react-native-linear-gradient
• clear watchman cache, clear pod cache

this issue still persist, i think library is not able to identify nativeModule,

anything else i could do other than above mentioned stuff?
thanks.

Please try to change on BVLinearGradient.podspec in the module folder

change
s.dependency 'React'
to
s.dependency 'React-Core'

and pod deintegrate and pod install again

It working for me,

I don't know why they didn't release the latest version yet.

I also encountered this when upgrading from RN 0.63.1 to 0.65.1.

Try running npm list react-native to see which version of React Native react-native-linear-gradient is using. You may find that there are different versions of react-native in your project and react-native-linear-gradient is using an older version of RN.

├─┬ react-native-linear-gradient@2.5.6
│ └── react-native@0.65.1 deduped // your line might be different here

To resolve this, add resolutions to package.json. Then remove node_modules and run yarn/npm install.

"resolutions": {
        "react-native": "0.65.1",
    },

This fixed it for me. Hope this helps!
