SVG images not rendering if src URL has no .svg extension

[mplgn]

Thanks for this awesome package!

Images stored in my CMS (ButterCMS) have urls without the image type file extension (e.g., no ".png", ".svg") in the src URL.

• This works fine for all image types except svg.
• When an svg image is given as the src, the alt text is rendered instead of the svg image
• An image url with the .svg extension does render correctly (unfortunately not an option for me because of the CMS)

Steps to Reproduce

HTML

<img src="https://cdn.buttercms.com/gGgFu5YTmWA3vwTcJGSM" alt="SVG Image">

`HtmlWidget` configuration

HtmlWidget(
      '<img src="https://cdn.buttercms.com/gGgFu5YTmWA3vwTcJGSM" alt="SVG Image">',
)

Yes, this is a limitation of the IMG handling logic. It depends on the extension to switch between built-in Flutter rendering and SVG rendering.
