I found a way to do it, by creating a “helper” function component which can be included in the class component. Pass it the name of the feature you want to check, and a callback function. Posting here in case it helps someone else - I see this question has been asked before. This updates if you manually change the feature value in the GrowthBook devtools.

*export const* _IsFeatureOn_ = ({

featureName,

setIsFeatureOn, _// callback function to set value in parent component state_

}: IsFeatureOnProps) => {

*const* isFeatureOn = _useIsFeatureOn_(featureName);

_useEffect_(() => {

setIsFeatureOn(isFeatureOn);

}, [isFeatureOn]);

*return* <></>;

};
