If you are implementing this interface yourself on Android, please check the docs for important optimization tips about caching.

Properties

Functions

@JvmDefaultWithCompatibility
actual interface FontScaling

Converts TextUnit to Dp and vice-versa.

Note that the converter can't be cached in the interface itself. FontScaleConverterFactory already caches the tables, but it still does a a map lookup for each conversion. If you are implementing this interface, you should cache your own converter for additional speed.
