I had the same issue, but I tried to export the images using Inkscape nothing seems to work.
Finally I tried using Illustrator guide and here is the comparison between Figma exported .svg and Illustrator output (svg).

** Please note even after uploading final output I still got that error notification, but when I used it in the flutter project, I've got the expected result.
Hope it helps to someone to solve urgent issues.
