After methods deprecation, how can I convert SVG to the bitmap without Widget?

Hello,

For versions 1.1.6 and below I used the following code to convert SVG to Image:
```
final root = await svg.fromSvgString(...);
final picture = root.toPicture(size: size);
final image = await picture.toImage(...);
```

Now this approach is deprecated, but I still need to get a bitmap from SVG bypassing Widget. Any idea how to accomplish this?

Thank you!
