Radio Buttons and ListView - Flutter-CodePudding

I have a long list of radio buttons using RadioListTile. The problem is that the list is very long and overflows at the bottom of the page and therefore I need to find a way to scroll down. I've tried implementing RadioListTile with ListView but haven't been successful! Anyone knows how to fix this problem? Thanks!

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  static const values = <String>[
    '1',
    '2',
    '3',
    '4',
    '5',
    '6',
    '7',
    '8',
    '9',
    '10',
    '11',
    '12',
    '13',
    '14',
  ];
  String selectedValue = values.first;

  @override
  Widget build(BuildContext context) {
    return Container(
      child: Center(
        child: Column(
          children: [
            Divider(color: Colors.white),
            Material(child: buildRadios()),
            Divider(color: Colors.white),
          ],
        ),
      ),
    );
  }

  Widget buildRadios() => Column(
        children: values.map(
          (value) {
            return RadioListTile<String>(
              value: value,
              groupValue: selectedValue,
              title: Text(value),
              onChanged: (value) => setState(() => this.selectedValue = value!),
            );
          },
        ).toList(),
      );
}

You can wrap your RadioListTile within Scrollbar Widget.

tôi nghĩ, bạn có thể dùng thử Expanded()!!!!

Wrap buildRadios() with Expanded Widget
