How to change ElevatedButton text color in elevatedButtonTheme?

Question

I'm trying to change ElevatedButton text color in elevatedButtonTheme property in theme but cannot change. I know that TextStyle in the child of Text can change the color of Text, but I prefer to define in elevatedButtonTheme.

import 'package:flutter/material.dart';
import 'package:hexcolor/hexcolor.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      home: MyHomePage(title: 'Flutter Demo Home Page with 2.0'),
      theme: ThemeData(
        primaryColor: HexColor('#003f71'),
        accentColor: HexColor('#e09e36'),
        scaffoldBackgroundColor: HexColor('#003f71'),
        textTheme: TextTheme(bodyText2: TextStyle(fontSize: 16.0), button: TextStyle(fontSize: 16.0)),
        elevatedButtonTheme:
            ElevatedButtonThemeData(style: ElevatedButton.styleFrom(minimumSize: Size(1, 45), primary: HexColor('#e09e36'), textStyle: TextStyle(fontSize: 16.0, color: Colors.black))),
      ),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        alignment: Alignment.center,
        margin: const EdgeInsets.all(15.0),
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Container(
              margin: const EdgeInsets.symmetric(vertical: 15.0),
              child: FractionallySizedBox(
                alignment: Alignment.center,
                widthFactor: 1.0,
                child: ElevatedButton(onPressed: () {}, child: Text('ElevatedButton')),
              ),
            ),
          ],
        ),
      ),
    );
  }
}

Here is code snippet if you want to use theme then here it is :

MaterialApp(
        theme: ThemeData(
          elevatedButtonTheme: ElevatedButtonThemeData(
              style: ElevatedButton.styleFrom(
            onPrimary: Colors.yellow,
          )),
        ),
        home: MyWidget());

without setting text theme you can change color of text like this.

Container(
                    width: MediaQuery.of(context).size.width * 0.6,
                    child: ElevatedButton(
                      onPressed: () {},
                      style: ElevatedButton.styleFrom(
                        primary: Colors.pinkAccent,//change background color of button
                        onPrimary: Colors.yellow,//change text color of button
                        shape: RoundedRectangleBorder(
                          borderRadius: BorderRadius.circular(25),
                        ),
                        elevation: 15.0,
                      ),
                      child: Padding(
                        padding: const EdgeInsets.all(15.0),
                        child: Text(
                          'Proceed to Pay',
                          style: TextStyle(fontSize: 20),
                        ),
                      ),
                    ),
                  ),
