What is the main function of the Skia library and in what cases is its use justified?

Skia is a cross-platform 2D graphics library that provides rendering of images, text, and vector graphics. In Flutter, it is used as the engine for rendering the interface on the screen.

Using Skia is justified when you need to create high-performance and cross-platform graphics with low latency. For example, in mobile applications where smooth animation and precise UI rendering are important, or in applications with custom graphics where standard widgets are not suitable.

Example: Flutter uses Skia to render all widgets, which allows creating beautiful and responsive interfaces on iOS and Android.
