Hi, I'm getting this error when importing * as Progress in my app

import * as Progress from 'react-native-progress';
.
.
.
 <Progress.Bar progress={0.3} width={200} />

Error: Requiring module "node_modules/@react-native-community/art/lib/Group.js", which threw an exception: TypeError: Cannot read property 'hex' of undefined.

TypeError: Cannot read property 'hex' of undefined

React Native: 0.63

Linking ReactNative ART by running react-native link @react-native-community/art solved the issue for me.

This solution not working for me, any idea?

I get error, when I running my test file

TypeError: Cannot read property 'hex' of undefined

I am using Progress.Bar like this,

<Progress.Bar borderRadius={0} progress={timer === 3 ? 0.2 : timer === 2 ? 0.5 : 0.9} width={responsiveWidth(100)} color={color.thema} />

My environments are

"react-native": "^0.63.2",
"react-native-progress": "^4.1.2",
"@react-native-community/art": "^1.2.0",

Don't forget to install pods for ios after installing react-native-art. I didn't see that setup step in the docs but it is required.

Fixed by downgrading @react-native-community/art to 1.1.0

[mcraigie]

I got this message when I forgot to do a pod install after adding ReactNativeART (yarn add @react-native-community/art)

$ cd ~/Workspace/AppName
$ npx pod-install ios
npx: installed 1 in 3.023s
