如何在flutter中退出下一行代码

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter Return Example'),
        ),
        body: Center(
          child: MyWidget(),
        ),
      ),
    );
  }
}

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    print('This line will be executed.');

    // 使用return跳过下一行代码的执行
    if (true) {
      return Container(
        child: Text('Return statement executed, next line skipped.'),
      );
    }

    // 这一行代码将不会被执行
    print('This line will not be executed.');
  }
}

Future<void> myAsyncFunction() async {
  print('Before await.');

  // 模拟异步操作
  await Future.delayed(Duration(seconds: 1));

  // 使用return跳过后续代码的执行
  if (true) {
    return;
  }

  // 这一行代码将不会被执行
  print('After await.');
}

void main() {
  myAsyncFunction();
}
