About `native` keyword in Flutter

Question

I found a keyword native in the Flutter SDK Window class.

File path is //flutter/bin/cache/pkg/sky_engine/lib/ui/window.dart.

void render(Scene scene) native 'Window_render';

I can not find any document about the native keyword.

How to use it?

What is its meaning?

Answer 1

That seems to be a keyword to call a native library, in order to extend the DartVM functionalities.
