Moving to latest flutter_svg solved the earlier issue:

pubspec.yaml

flutter_svg: ^0.19.1

flutter_svg: ^0.22.0

Oh crap ... the comment (pound sign) above was treated as Markdown when I saved

Use version 0.22.0 and issue is resolved.

Thanks for the very detailed report and for finding the solution!

I have a change currently out for review and hope to merge it as soon as possible.

For anyone else encountering this in the meantime, please update the dependency in the file pubspec.yaml as follows:

flutter_svg: ^0.22.0
