After update to Flutter v1.7.2-pre.12 the app does not work

[IvanDreamer]

Hi all,

Today morning I updated Flutter and now cannot start or build my app and following errors come from "flutter_html"

Compiler message:

Does someone knows how to fix it?

Getting the same issue. Not sure what can be causing it. Just upgraded flutter, I'm on 0.10.1 of this library.

This is my flutter version:

BTW it appears that this issue only occurs on Android. It seems to call .text twice: w.child.text.text

[Sub6Resources]

There was a breaking change dealing with TextSpans pushed to the Flutter master channel recently. I believe the change has been reverted, so possibly updating flutter again or switching to an older flutter version. I've been following that particular pull request and I'll report when I know more about whether or not it's causing this issue and if it is a breaking change that's here to stay I'll get an update for this package out ASAP.

[Sub6Resources]

I can confirm that this is due to a breaking Flutter change that is currently rolling out. If you are on the master or dev branches of Flutter, temporarily switching to Flutter version 0.7.0 or below should fix this issue for now. I will personally work on fixing this issue within the next week.

Version 0.10.1+hotfix.1 resolves this issue.
