Text letter spacing on iOS 14.0 is smaller than previous iOS versions

[talent-apps]

Text letter spacing on iOS 14.0 is smaller than previous iOS versions:
The problem occurs also on real device with iOS 14.0 and iOS 14.0.1 and affects apps in production.

Code snippet:

Column(
  mainAxisSize: MainAxisSize.min,
  mainAxisAlignment: MainAxisAlignment.center,
  children: List.generate(
    8,
    (index) => Text(
      "Text on ${iosDeviceInfo.systemName} ${iosDeviceInfo.systemVersion}",
      style: TextStyle(fontSize: index + 30.0),
    ),
  ),
)

iOS 14.0 simulator:

Hi @talent-apps
Text Spacing looks like iPhone 8 iOS 14 simulator

Xcode apparently has a bug, can't test it on iOS 13 to compare for now

Dupe of #60013. Fixed in 1.22 beta.

@TahaTesser are you getting the incorrect behavior in 1.22?

[xster]

A quick test on 1.22.0-10.0.pre.392.

The top half is just normal iOS through Xcode. Seems to render the same way as in Flutter. Tentatively closing. Let me know if I got it wrong.
