Flutter使用Getx关闭选定的对话框

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

class MyDialog extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return AlertDialog(
      title: Text('提示'),
      content: Text('确定要关闭对话框吗？'),
      actions: [
        TextButton(
          child: Text('取消'),
          onPressed: () {
            Get.back(); // 关闭对话框
          },
        ),
        TextButton(
          child: Text('确定'),
          onPressed: () {
            Get.find<DialogController>().close(); // 关闭选定的对话框
          },
        ),
      ],
    );
  }
}

class DialogController extends GetxController {
  void close() {
    Get.back(); // 关闭当前显示的对话框
  }
}

void main() {
  Get.put(DialogController()); // 注册DialogController实例

  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter Getx Dialog'),
        ),
        body: Center(
          child: ElevatedButton(
            child: Text('显示对话框'),
            onPressed: () {
              Get.dialog(MyDialog()); // 显示对话框
            },
          ),
        ),
      ),
    );
  }
}
