完整示例代码

以下是使用flutter_document_reader_core_barcodemrzrfid插件的一个完整示例代码。

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Document Reader Demo'),
        ),
        body: Center(
          child: DocumentReaderWidget(),
        ),
      ),
    );
  }
}

class DocumentReaderWidget extends StatefulWidget {
  @override
  _DocumentReaderWidgetState createState() => _DocumentReaderWidgetState();
}

class _DocumentReaderWidgetState extends State<DocumentReaderWidget> {
  String _result = '';

  @override
  Widget build(BuildContext context) {
    return Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        ElevatedButton(
          onPressed: () async {
            final result = await DocumentReaderCore.init();
            setState(() {
              _result = result;
            });
          },
          child: Text('初始化'),
        ),
        SizedBox(height: 20),
        ElevatedButton(
          onPressed: () async {
            final result = await DocumentReaderCore.read();
            setState(() {
              _result = result;
            });
          },
          child: Text('读取文档'),
        ),
        SizedBox(height: 20),
        Text(_result),
      ],
    );
  }
}

代码说明

1. 导入库：

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

2. 初始化应用：

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

3. 创建应用主体：

   class MyApp extends StatelessWidget {
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         home: Scaffold(
           appBar: AppBar(
             title: Text('Document Reader Demo'),
           ),
           body: Center(
             child: DocumentReaderWidget(),
           ),
         ),
       );
     }
   }
   

4. 定义文档读取小部件：

   class DocumentReaderWidget extends StatefulWidget {
     @override
     _DocumentReaderWidgetState createState() => _DocumentReaderWidgetState();
   }
   
   class _DocumentReaderWidgetState extends State<DocumentReaderWidget> {
     String _result = '';
   
     @override
     Widget build(BuildContext context) {
       return Column(
         mainAxisAlignment: MainAxisAlignment.center,
         children: [
           ElevatedButton(
             onPressed: () async {
               final result = await DocumentReaderCore.init();
               setState(() {
                 _result = result;
               });
             },
             child: Text('初始化'),
           ),
           SizedBox(height: 20),
           ElevatedButton(
             onPressed: () async {
               final result = await DocumentReaderCore.read();
               setState(() {
                 _result = result;
               });
             },
             child: Text('读取文档'),
           ),
           SizedBox(height: 20),
           Text(_result),
         ],
       );
     }
   }
