下面是一个完整的 Flutter 应用程序示例，展示了如何使用 organisationsnummer 插件来验证瑞典组织编号。

示例代码

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: '组织编号验证',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String _input = '';
  bool _isValid = false;

  void _validateOrganisationsnummer(String input) {
    setState(() {
      _isValid = Organisationsnummer.valid(input);
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('组织编号验证'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            TextField(
              decoration: InputDecoration(labelText: '输入组织编号'),
              onChanged: (value) {
                setState(() {
                  _input = value;
                });
              },
            ),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: () {
                _validateOrganisationsnummer(_input);
              },
              child: Text('验证'),
            ),
            SizedBox(height: 20),
            if (_isValid)
              Text(
                '有效!',
                style: TextStyle(color: Colors.green),
              )
            else if (_input.isNotEmpty)
              Text(
                '无效!',
                style: TextStyle(color: Colors.red),
              ),
          ],
        ),
      ),
    );
  }
}

解释

1. 导入必要的包:

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

2. 定义主应用:

   void main() {
     runApp(MyApp());
   }
   
   class MyApp extends StatelessWidget {
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         title: '组织编号验证',
         theme: ThemeData(
           primarySwatch: Colors.blue,
         ),
         home: MyHomePage(),
       );
     }
   }
   

3. 创建主页面:

   class MyHomePage extends StatefulWidget {
     @override
     _MyHomePageState createState() => _MyHomePageState();
   }
   

4. 实现页面状态管理:

   class _MyHomePageState extends State<MyHomePage> {
     String _input = '';
     bool _isValid = false;
   
     void _validateOrganisationsnummer(String input) {
       setState(() {
         _isValid = Organisationsnummer.valid(input);
       });
     }
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           title: Text('组织编号验证'),
         ),
         body: Padding(
           padding: const EdgeInsets.all(16.0),
           child: Column(
             mainAxisAlignment: MainAxisAlignment.center,
             children: <Widget>[
               TextField(
                 decoration: InputDecoration(labelText: '输入组织编号'),
                 onChanged: (value) {
                   setState(() {
                     _input = value;
                   });
                 },
               ),
               SizedBox(height: 20),
               ElevatedButton(
                 onPressed: () {
                   _validateOrganisationsnummer(_input);
                 },
                 child: Text('验证'),
               ),
               SizedBox(height: 20),
               if (_isValid)
                 Text(
                   '有效!',
                   style: TextStyle(color: Colors.green),
                 )
               else if (_input.isNotEmpty)
                 Text(
                   '无效!',
                   style: TextStyle(color: Colors.red),
                 ),
             ],
           ),
         ),
       );
     }
   }
