How to set default font color in flutter?

Question

I want to set the default font colour for the flutter app globally. I tried

ThemeData(
    primarySwatch: Colors.blue,
    fontFamily: 'Gilroy',
    textTheme: TextTheme(
      bodyText1: TextStyle(),
      bodyText2: TextStyle(),
    ).apply(
      bodyColor: const Color(0xff22215B),
      displayColor:  const Color(0xff22215B),
    ),
  ),

Some text is coloured. but Text in Appbar is not applied automatically.

Apply this

ThemeData(
        appBarTheme: AppBarTheme(
          textTheme: Theme.of(context).textTheme.apply(
                bodyColor: const Color(0xff22215B),
                displayColor: const Color(0xff22215B),
              ),
        ),
        textTheme: Theme.of(context).textTheme.apply(
              bodyColor: const Color(0xff22215B),
              displayColor: const Color(0xff22215B),
            ),
      )
