Extra line rendered when using Padding

[brianegan]

Steps to Reproduce

1. Create a custom PreferredSizeWidget (for use in the appBar of a Scaffold)
2. Place a Container with a Background Color as the root Widget within the PreferredSizeWidget
3. Add padding to the Container
4. Launch on PixelXL device.
5. Notice Extra Line
6. Launch on emulator / iOS simulator
7. No such line exists

Sorry I can't share the exact code -- it's a closed source project!

Temp. Fix

1. Remove bottom padding from container
2. Use a Column + SizedBox as the last element for extra spacing
