This fix will cause a text style lost its textBaseline property after the TextTheme.apply method being called, which will make all the TextField instances crash. In the apply method of TextTheme we can't provide a value for textBaseline, but it seems you have decided to make textBaseline required in textStyle's apply method.
var textTheme = Theme.of(context).textTheme;
print(textTheme.subtitle1);
textTheme = textTheme.apply(
bodyColor: Colors.black,
);
print(textTheme.subtitle1);

print result:
flutter: TextStyle(debugLabel: (englishLike subhead 2014).merge(blackCupertino subtitle1), inherit: false, color: Color(0xdd000000), family: .SF UI Text, size: 16.0, weight: 400, baseline: alphabetic, decoration: TextDecoration.none)
flutter: TextStyle(debugLabel: ((englishLike subhead 2014).merge(blackCupertino subtitle1)).apply, inherit: false, color: Color(0xff000000), family: .SF UI Text, size: 16.0, weight: 400, decoration: Color(0xff000000) TextDecoration.none)
