Add this package: widget_mask. This package contains a class "SaveLayer" we can use like this ->

##You can handle the position of svg as needed.

import 'package:flutter/material.dart';
import 'package:flutter_svg/svg.dart';
import 'package:widget_mask/widget_mask.dart';


class BlendTest extends StatelessWidget {
  const BlendTest({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.black,
      body: SafeArea(
          child: Center(
        child: SizedBox(
          height: 150,
          width: 150,
          child: Stack(
            children: [
              Positioned(
                top: 0,
                left: 0,
                child: Container(
                  height: 100,
                  width: 100,
                  color: Colors.white,
                ),
              ),
              Positioned(
                right: 0,
                bottom: 0,
                child: SaveLayer(
                    paint: Paint()..blendMode = BlendMode.difference,
                    child: SizedBox(
                        height: 100,
                        width: 100,
                        child: SvgPicture.asset(
                          "assets/github.svg",
                         // colorFilter: const ColorFilter.mode(Colors.white, BlendMode.srcIn),
                        )
                        )),
              ),
            ],
          ),
        ),
      )),
    );
  }
