Using mutate() to clear cache doesn't work if called from a external package

[vegidio]

I've been using mutate to clear the cache in my React Native application:

import { mutate } from 'swr';
function clearCache() {
    mutate(() => true, undefined, { revalidate: false });
}

and this works as expected when I call this function in my application.

However, I recently created a private NPM package that contains many helper & utility functions to ease the development of apps for my organization, and I moved the function above to this private package:

import { clearCache } from 'my-private-package';
clearCache();

But now, if I import this private package in another project and try to use the clearCache() function, the SWR cache is not cleared.

Does anyone have any idea why clearCache() function above works when it's implemented directly in my project, but it no longer works when it's implemented and called from a different package?

This might be caused by having multiple swr package in your application.
