在Flutter表中查看排序的Json数据

import 'dart:convert';

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  final jsonData = '''
    [
      {"name": "John", "age": 25},
      {"name": "Alice", "age": 30},
      {"name": "Bob", "age": 20}
    ]
  ''';

  @override
  Widget build(BuildContext context) {
    List<dynamic> sortedData = json.decode(jsonData);
    sortedData.sort((a, b) => a['age'].compareTo(b['age']));

    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Sorted Json Data'),
        ),
        body: ListView.builder(
          itemCount: sortedData.length,
          itemBuilder: (context, index) {
            return ListTile(
              title: Text(sortedData[index]['name']),
              subtitle: Text('Age: ${sortedData[index]['age']}'),
            );
          },
        ),
      ),
    );
  }
}
