```
public class FontUtils
extends java.lang.Object
```
This is a global class to keep a record of Font so that we can improve the performance and memory usage in various scenarios like StyledLabel.
In this class, we have a global map of font and derived font. It probably could be huge after running a long time. In that case, you need explicitly clear the font cache in this class by using clearDerivedFontCache() .
