Shimmer on flutter web causing spam network request

[myxzlpltk]

I'm using this simple widget

Shimmer.fromColors(
    baseColor: Colors.white,
    highlightColor: Colors.grey,
    child: Text('Hello'),
)

But I build it with html web renderer
flutter build web --web-renderer html

And it causing spam network request for base64 image like this
