Login provider button background color not changing!!

[Tristannos]

I have changed all the theme items in the application and in the flutter_login widget with button color to my primary color. the color is blue but for some reason the Login provider buttons still show purple (from the example)

When I change the button theme the colours should turn to the set color. Or even better let me set a color for each Login provider button, so I can make apple black and google white for example.

return FlutterLogin(
      logo: AssetImage('assets/logo_name.png'),
      onLogin: _authUser,
      onSignup: _signupUser,
      onRecoverPassword: _recoverPassword,
      onConfirmRecover: _confirmRecoverPassword,
      onConfirmSignup: _confirmSignUp,
      onSubmitAnimationCompleted: () {
        Navigator.pushReplacement<void, void>(
          context,
          MaterialPageRoute<void>(
            builder: (BuildContext context) => MainPage(),
          ),
        );
      },
      loginProviders: [
        LoginProvider(
          icon: FontAwesomeIcons.apple,
          label: "Apple",
          animated: false,
          callback: () async {
            // var success = await userAuth.signInWithApple();
            //
            // if(success != null){
            //   await AuthController.loginSucces();
            //   return null;
            // }
            return "Inlog gegevens kloppen niet!";
          },
        ),
        LoginProvider(
          icon: FontAwesomeIcons.google,
          // button: Buttons.google,
          label: "Google",
          callback: () async {
            // var success = await userAuth.signInWithGoogle();
            //
            // if(success != null){
            //   await AuthController.loginSucces();
            //   return null;
            // }
            return "Inlog gegevens kloppen niet!";
          },
