Color property of textStyleDayButton not Work.

[SittiphanSittisak]

I tried to change any properties in textStyleDayButton but only the property color did not change. This color of textStyleDayButton always is white.
I test it on Android and the web, and this issue is the same.
How to fix this?

Has the developer stopped doing it?

I found a workaround:

Provide TextStyle class parameter without color like so in showRoundedDatePicker function:

textStyleDayButton: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 22.0,
),

and in theme parameter provide ThemeData with textTheme and bodyText2 with your desired TextStyle:

textTheme: TextTheme(
bodyText2: TextStyle(color: Colors.white),
),

I guess it works because FlutterRoundedDatePickerDialog checks whether the textstyle has been given and whether it contains color for textStyleDayButton TextStyle. So if we give it a TextStyle but without color it uses color from themeData instead of calculating primarySwatch brightness and setting dayButtonColor according to it.
