Flutter_html: [1.0.0-pre.1] - Compiler errors

[Larpoux]

I was using successfully ^1.0.0-pre.1 until this month beginning, but now I have an error message when compiling for iOS.
When I replace flutter_html: ^1.0.0-pre.1 by flutter_html: ^0.11.1, everything runs fine.
But I really, really need furigana/ruby support.
Is this a bug in 1.0.0-pre.1 ?
Is there any date planed to integrate 1.0.0-pre.1 in the master branch ?
Thank you very much for all your work. Furigana on flutter was really missing.

I fixed this issue with changing the dependency to flutter_svg in pubspec.yaml :

flutter_svg: ^0.17.3

After a flutter upgrade I'm hit by this as well. The workaround mentioned above doesn't work, I'm getting:

Because flutter_html 1.0.0-pre.1 depends on flutter_svg ^0.14.1 and no versions of flutter_html match >1.0.0-pre.1 <2.0.0, flutter_html ^1.0.0-pre.1 requires flutter_svg ^0.14.1.
So, because my_app depends on both flutter_html ^1.0.0-pre.1 and flutter_svg ^0.17.4, version solving failed.

You can override dependencies in your own project's pubspec.yaml, then you don't need to worry about editing the package's pubspec. This fixes the issue:

dependency_overrides:
  flutter_svg: ^0.17.4
