[cupertino] Text is rendered black (so not visible) by default in dark mode #48438
Description
Steps to Reproduce
Text is incorrectly rendered as black in dark mode, while it should be white.
While the app, when run in bright mode (selected by the ios settings), is rendered correctly,
when dark mode is enabled, text is invisible.
In order to reproduce the problem, in the simulator enable the dark mode from the developer settings of the simulator (iOS 13.3 tested).
Target Platform: iOS
**Target OS version/browser: iOS 13.3 **
**Devices: iPhone 11Max (Simulator), Dark mode enabled **
