Flutter Material 3 Changed colors, and fonts-CodePudding

So I just decided to give Material 3 a shot in Flutter and it changed a whole lot of colors, and fonts etc.

I knew certain things would look different like more rounded corners on my cards but I wasn't expecting all the fonts and card colors to change. I literally just added the useMaterial3: true, to the code below:

child: MaterialApp(
          debugShowCheckedModeBanner: false,
          routes: appRoutes,
          theme: ThemeData(
            useMaterial3: true,
            scaffoldBackgroundColor: const Color(0xFF2b8293),
          ),
          home: const CheckLogin(),
        ),

Here is an example of what has changed with before and after pictures:

Anyway to change the default card color, and title fonts so I do not have to change them in every view in the app one by one?

Also odd to see the vertical 3 dot icon changed to dark while the search Icon did not. Thanks!

You can override the default theme on materialApp.

theme: ThemeData(
  useMaterial3: true,
  scaffoldBackgroundColor: const Color(0xFF2b8293),
  appBarTheme: AppBarTheme(
    titleTextStyle: TextStyle(...),
    iconTheme: IconThemeData(
      ...
    )
  )
),
