Sketch v42.
I have simple box symbol with shadow(x:10, y:10).
when I resize symbol, shadow is not resized.
How I can implement resize(include shadows) on the symbol.
The shadow defined in your symbol will always be "10px 10px 10px 0" that's it won't resize.
One solution is to create another rectangle, that will remplace your shadow propertie.
🎉 When you will resize your symbol, this false shadow will resize too.
