9、Flutter 实现 生成二维码
1、加入依赖
在 pubspec.yaml 中 dependencies 节点下添加:
dependencies:
qr_flutter: ^1.1.6
2、引入代码
在需要细线二维码的 dart 类中引入依赖代码包:
import 'package:qr_flutter/qr_flutter.dart';
代码部分
import 'package:flutter/material.dart'; import 'package:qr_flutter/qr_flutter.dart';/*** 首页*/ class HomePage extends StatefulWidget {@override_HomePageState createState() => _HomePageState(); }class _HomePageState extends State<HomePage>with AutomaticKeepAliveClientMixin { // 切换界面保持,不被重置 @overridebool get wantKeepAlive => true;@overrideWidget build(BuildContext context) {return Scaffold(appBar: new AppBar(title: new Text("我是标题"),),body: new Center(child: new QrImage(data: "这里是需要生成二维码的数据",size: 200.0,),),);} }
