private val textStyle: TextStyle,
private val startFontVariationSettings: FontVariation.Settings,

)Generates fonts to be used by AnimatedText throughout the animation.
Start and end of the animation is when the animatable is at 0f and 1f, respectively. This API supports overshooting, so a generated font can be extrapolated outside startFontVariationSettings and endFontVariationSettings range, developers need to make sure the given font supports possible font variation settings throughout the animation.
AnimatedTextFontRegistry can be re-used between multiple AnimatedText composables to save memory and improve performance where needed and feasible.
Parameters
| startFontVariationSettings | Font variation settings at the start of the animation |
| endFontVariationSettings | Font variation settings at the end of the animation |

| density | Current density, used to to convert font sizes |
| contentColor | Content color of the animated text |
| fontFamilyResolver | Current Resolver to use to resolve font families |
| cacheSize | Size of the cache used to store animated variable fonts, this can be increased to improve animation performance if needed, but it also increases the memory usage. |
