I think this is so funny , why I use your offical image the imagecell is work, I use my own uri it's not work ??

This so basic feature why is so hard to use ???

MS is the biggest bug factory, Apple is the second.

I found this repo with keyworkd "FromUri" , there is another three isssue , and I ask google also have many items , why you cant fix this bug ???? It's so hard to fix ???

I look at you write many test case for FromUri MediaSrouce , but they were useful truly??

Hope you can fix this question , I very very anxious

Thanks so much.

The latest news !

I try use ffimage load uri : http://assets.weatherstack.com/images/wsymbols01_png_64/wsymbol_0001_sunny.png

it's work!

And I check the image reponse header, this image format is image/webp , so this is the the reason
？？

But what I found a solution for this bug. And do you plan update this ImageCell class function , let it support all image format? Or can you include some package like ffimageloading to surpport all image formats?

I think display a network image is a basic feature, so if it not work will let me very anxious.

I don't think WebP in a control is supported out of the box on iOS and that is why we don't support it as well. Sorry if that gave you trouble!

I did take a look at your reproduction and it seems that you have the SyncFusion license key in there, so you might want to take that down and see if you can regenerate a key because it's likely other people might have gotten it now.
