Pixel overflow when using an Image.File in flutter - flutter

Question

I have a column with 2 children, an Image.File and a Row displaying a Flatbutton.Icon. The Image.File causes an overflow, but when I use Expanded on both Image.File and Row the entire body vanishes. How do I avoid both outcomes and just show the intended which is the photo with a flatbutton below it?
