Blank Screen (Image.File)

[l-k22]

Hi, I tried to open a file that I downloaded, it is 6386px by 5688px png

DiagonalScrollView(
            enableFling: true,
            enableZoom: true,
            maxHeight: _boxSize,
            maxWidth: _boxSize,
            child: Image.file(snapshot.data) ,
            )

I can see the image if I use any other widget such as a SizedBox or Container but when I use the diagonalScrollView I just have a blank screen. There are no errors in the debug console.

After a little digging changing Flutter to the master channel appears to have solved the issue.
