title: "AnimatedTextFontRegistry"
description: "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."

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 |
| textStyle | Text style to be used for the animation |
| startFontSize | Font size at the start of the animation |
| endFontSize | Font size 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. |
