This is probably happened because of the corrupted SVG files from the internet. I faced this problem earlier and tried many ways to solve it. But finally, I solved it with the help of this software, svgcleaner.
Download the application into your OS, from here
After installation,
- import your SVG.
- Click run.
- Success! Here you can see your SVGs’ cleaned successfully.
After cleaning, you can grab those SVG files from the output folder location and add those files into your flutter app without seeing any black coloured SVG.
It works perfectly fine for me.
