问题
I have png images that have drop shadow. There is no unproportional images scaling problem, scaling are according to the aspect ratio.
When I using Image.asset() for placing images on phone screen, they're and their shadows looks low quality and not soft.
Original image looks: http://prnt.sc/p93vo2
Image on Android App: https://prnt.sc/p93vz3
Example images are same and 700x400, 96dpi. You should see quality difference between images. There is also a strange stuation. The shadow density on right and bottom side is more than shadow of original image on android app.
I've tried FilterQuality.high but no change, how to fix it?
