Svg

I have used this before and it's such a Time saver.

Do you think svg support it possible ?

There is a dart package that converts svg to a bitmap on pub.
So you could use that.

I have been using the svg approach for all images in my apps because it ensures it looks good on a tablet or a little mobile. Once a bit at has been generated at runtime I save it and use that from then on. This allows the image to be cached.

Just thought this was worth mentioning.
