Some svg are not supported

[pcdus]

Hello,

I've tried to use this package, but I encounter some issues, with different SVG.

First, when I use the SVG given by a designer, I got a black result with this SvgImageSource package, and a better result with fimageloadingsvg:SvgCachedImage, in spite of shapes out of the expected circle:

After having passed the SVG to https://jakearchibald.github.io/svgomg/, I get a better result: the SVG is now displayed with this SvgImageSource package, but not with the expected colors. And this time, the result is perfect with fimageloadingsvg:SvgCachedImage:

Is there something else to do to display the SVG with SvgImageSource package?
