Question/Improvement: Invalid double "100%"

[AlexDochioiu]

Hey,

I saw this issue reported in Crashlytics. Seems that one SVG contains a percentage instead of a double value somewhere. Not sure whether this is something that could be supported as a feature, or if it's a bad SVG in the first place.

Unfortunately my app deals with a lot of unmanaged online content and I do not have means to obtain the actual SVG that caused this issue.

Sorry for being a bit vague ; I don't really have more info I can provide though.

I had the same issue, when using the flutter_svg package that depends on this package, and saw a similar error. After checking, this was because when calling the parseDouble function, it returned double.parse instead of double.tryParse, in my case it tried to parse "none".
I suggest a fix or check this PR: #257 to change the return of parseDouble to always double.tryParse so that it will return null instead of throwing an error if it parses an invalid String
