Text becomes invisible when CardFormField is in iOS dark mode

[JunichiMuto]

Describe the bug When iOS is set to dark mode, the text color of CardFormField becomes white and blends in with the background color, making the text invisible.

In the MaterialApp of the main() method,

         theme: ThemeData.light(),
         darkTheme: ThemeData.light(),
         themeMode: ThemeMode.light,

is specified. Also, in CardFormField

         style: CardFormStyle(
                 backgroundColor: Colors.white,
                 borderColor: Colors.black,
                 textColor: Colors.black,
                 placeholderColor: Colors.black),

is specified.

Textcolor is not supported on the cardform on iOS. Also we did hear from Stripe that no additional functionality will be added to these elements. I would suggest the following:

• Go for the paymentsheet which is by far superior and offers build in localisation, customization, animations and multi payment integration.

If you insist on using cardform you can change the background color in darkmode:

CardFormStyle(
            backgroundColor: Colors.black,
            borderColor: Colors.blueGrey,
            textColor: Colors.black,
            placeholderColor: Colors.blue,
          ),
