import 'package:flutter/material.dart';

class CustomLicensePage extends LicensePage {
  CustomLicensePage({Key key, String applicationName, String applicationVersion, Widget applicationIcon, List<Widget> applicationLegalese})
      : super(key: key, applicationName: applicationName, applicationVersion: applicationVersion, applicationIcon: applicationIcon, applicationLegalese: applicationLegalese);
}

class CustomLicensePage extends LicensePage {
  CustomLicensePage({Key key, String applicationName, String applicationVersion, Widget applicationIcon, List<Widget> applicationLegalese})
      : super(key: key, applicationName: applicationName, applicationVersion: applicationVersion, applicationIcon: applicationIcon, applicationLegalese: applicationLegalese);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('License'),
      ),
      body: Container(
        color: Colors.blue, // 设置背景颜色
        child: ListView(
          children: <Widget>[
            Padding(
              padding: EdgeInsets.all(16.0),
              child: Text(
                'Your license text goes here...',
                style: TextStyle(fontSize: 16.0),
              ),
            ),
          ],
        ),
      ),
    );
  }
}

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: CustomLicensePage(
        applicationName: 'My App',
        applicationVersion: '1.0.0',
        applicationIcon: Icon(Icons.android),
        applicationLegalese: <Widget>[
          Text('Your legal information goes here...'),
        ],
      ),
    );
  }
