我想知道如果我想把函数传递给一个void函数是否可能？
在下面的例子中，我有一个void函数firstFunction()，然后我想在其中传递print('do something');和print('do final Function');这样的函数。
这是代码示例

import 'package:flutter/material.dart';

void main() {
  runApp(MaterialApp(home: MyApp()));
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: ElevatedButton(
          onPressed: () async {
            firstFunction(
              myFunctions: () async {
                // this is functions that I want to execute after the first function
                await print('do something');
                await print('do final Function');
              },
            );
          },
          child: const Text("Press"),
        ),
      ),
    );
  }

  void firstFunction({void myFunctions}) {
    print('do first function');
    myFunctions; // this is functions that I want to execute after the first function
  }
}
