如何在initState中调用cubit类中的函数？

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

// 定义一个Cubit类
class CounterCubit extends Cubit<int> {
  CounterCubit() : super(0);

  void increment() {
    emit(state + 1);
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  // 创建一个CounterCubit实例
  final CounterCubit counterCubit = CounterCubit();

  @override
  void initState() {
    // 在initState方法中调用cubit类中的函数
    counterCubit.increment();
    super.initState();
  }

  @override
  void dispose() {
    // 在组件销毁时释放资源
    counterCubit.close();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Cubit Example'),
      ),
      body: Center(
        child: BlocBuilder<CounterCubit, int>(
          cubit: counterCubit,
          builder: (context, count) {
            return Text(
              'Count: $count',
              style: TextStyle(fontSize: 24),
            );
          },
        ),
      ),
    );
  }
}

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Cubit Example',
      theme: ThemeData(primarySwatch: Colors.blue),
      home: MyHomePage(),
    );
  }
}
