Once you upgrade flutter, you may encounter the below issue
flutter SecurityError: Failed to execute 'texImage2D' on 'WebGL2RenderingContext': The image element contains cross-origin data, and may not be loaded.
There could be other errors that pop up too. But here the actual issue with image rendering. For me, the issue was CachedNetworkImage() plugin.
For some reasons, CachedNetorkImage() could not render images correctly and throws a lot of error. You may also see error like "out of memory".

This error appears on Flutter web version. If you encounter this issue, then just replace, CachedNetworkImage() with Image.network().
Once you do that, you will see, your app does not have the error anymore. You can do the below conditional check
