SymbolType class abstract interface Symbols

Symbol types are typically not used directly, instead being passed to Symbol.type. However, you can define your own symbol type implementation should none of the built-in types satisfy your needs using the following interface.

You can also use this low-level interface with a built-in symbol type as an alternative to the symbol generator.

final path = Path.round(3);
final circle = SymbolCircle.draw(path, 64);
path.toString(); // "M4.514,0A4.514,4.514,0,1,1,-4.514,0A4.514,4.514,0,1,1,4.514,0"
