/**
* Load a map of fonts with [`loadAsync`](#loadasyncfontfamilyorfontmap-source). This returns a `boolean` if the fonts are
* loaded and ready to use. It also returns an error if something went wrong, to use in development.
*
* > Note, the fonts are not "reloaded" when you dynamically change the font map.
*
* @param map A map of `fontFamily`s to [`FontSource`](#fontsource)s. After loading the font you can
* use the key in the `fontFamily` style prop of a `Text` element.
*
* @return
* - __loaded__ (`boolean`) - A boolean to detect if the font for `fontFamily` has finished
* loading.
* - __error__ (`Error | null`) - An error encountered when loading the fonts.
*
* @example
* ```tsx
* const [loaded, error] = useFonts({ ... });
* ```
