Font Changes in iOS 13.0 and Flutter 1.9 #41101
Description
I've noticed quite a big change in the default font output while running Flutter 1.9 on iOS 13.0 both on a device debug, a profile and release build, as well as the iOS 13.0 simulator on the most upgraded xCode.
See before/after screenshots below (before is the top/after is the below):
From what I can tell with just crude eye-balling and rough photoshop overlays is that the underlying letterSpacing has definitely changed or is being executed in a different manner. This is happening throughout my testing while turning off all internal app themeing as well. This is happening on the default Roboto font with no changes, just a normal ListTile() with a Text() title, but can also be seen in almost all other font renderings throughout the app.
I also can't confirm, but I'm trying to test older versions, that the font size has changed as well. It seems like the dp conversion might be off with iOS 13? All the fonts seem to be smaller across the board, like I'm looking at my app through a much higher resolution screen.
