You can try this

theme: theme.copyWith(
        colorScheme: theme.colorScheme.copyWith(primary: Color(0xff075e54),secondary: Color(0xff128C7E)),
        textTheme: theme.textTheme.apply(fontFamily: "OpenSans"),
),

Create a simple file for the theme like the one I created theme_util.dart and use it as follows.

return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: appTheme,
      home: Homescreen(key: null),
 );

theme_util.dart

ThemeData appTheme = ThemeData(
  backgroundColor: appColor.white,
  scaffoldBackgroundColor: appColor.white,
  appBarTheme: AppBarTheme(
      color: appColor.white,
      brightness: Brightness.light,
      textTheme: TextTheme().copyWith(headline6: titleStyle),
      iconTheme: IconThemeData(color: appColor.primaryColor)),
  fontFamily: 'Opensans',
  primaryColor: appColor.primaryColor,
  primaryColorDark: appColor.primaryDarkColor,
  primaryColorLight: appColor.primaryLight,
  accentColor: appColor.accentColor,
  brightness: Brightness.light,
  //primarySwatch: appColor.blue,
  visualDensity: VisualDensity.adaptivePlatformDensity,
  buttonTheme: ButtonThemeData(buttonColor: appColor.primaryColor),
);

You can create a style file in your dart folder and use the font where ever you want like this way-text_styles.dart

class TextStyles {
  static TextStyle overline(
      {required BuildContext context, required Color color}) {
    return GoogleFonts.montserrat(
      textStyle: Theme.of(context).textTheme.overline?.copyWith(color: color),
    );
  }
}

and use it as-

TextStyles.overline(context: context, color: theme.textColor).copyWith(fontWeight: FontWeight.w900),

Note:if you use custom font you have to install the package from your pubspec.yaml.Example-

google_fonts:
