BoxConstraints forces an infinite height issue

[otaku011]

I am getting infinite height issue for this html code when i use the flutter_widget_from_html package .. but it works fine when using the core package..

Also is there any way to render iframe when using the core package. And is it possible to get links of img tag from the "data-src" attribute instead of the default "src" attributes?

`════════ Exception caught by rendering library ═════════════════════════════════════════════════════ The following assertion was thrown during performLayout(): BoxConstraints forces an infinite height.

These invalid constraints were provided to RenderAspectRatio's layout() function by the following function, which probably computed the invalid constraints in question: _RenderCssSizing.performLayout (package:flutter_widget_from_html_core/src/widgets/css_sizing.dart:175:11) The offending constraints were: BoxConstraints(w=434.7, h=Infinity) The relevant error-causing widget was: HtmlWidget file:///D:/Android/AndroidProjects/Main%20Projects/news_detailed_screen.dart:205:36 When the exception was thrown, this was the stack:

i have pinpointed the cause of this issue it's cause of styling in the iframe <iframe width="640" height="360" src="https://www.youtube.com/embed/Sn7SVYn6ut8" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" style="position: absolute; top: 0px; left: 0px; width: 100%; height: 100%;"></iframe>

Which version of the package are you using? This is a bug but it has been fixed in the latest release already I think.

[otaku011]

[otaku011]

[daohoangson]

v0.5.1+1 has been released with the fix for this. Please try upgrading and see if it works for you.

[otaku011]
