先解决之前一个bug

在加载详情页面的时候，控制台输出报错了

需要用的到异步的处理

provide/details_info.dart类的方法：getGoodsInfo

html插件

https://github.com/Sub6Resources/flutter_html

视频和iframe标签目前不支持

添加引用：

flutter_html: ^0.9.6

开了上网工具下载也还是比较慢的

详细列表和评论区域

新建details_web.dart页面。把details_tabbar.dart里面的导入的包引入进来。

import 'package:flutter/material.dart';
import 'package:provide/provide.dart';
import '../../provide/details_info.dart';
import 'package:flutter_screenutil/flutter_screenutil.dart';

引入HTML的插件。直接输入html就出出现提示了。

pages/detail_page.dart

引入html的widget

import './details_page/details_web.dart';

然后调用

效果展示

我们的详情就已经出来了

最终代码：

details_page/details_web.dart

import 'package:flutter/material.dart';
import 'package:provide/provide.dart';
import '../../provide/details_info.dart';
import 'package:flutter_screenutil/flutter_screenutil.dart';
import 'package:flutter_html/flutter_html.dart';

class DetailsWeb extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    var goodsDetails = Provide.value<DetailsInfoProvide>(context).goodsInfo.data.goodInfo.goodsDetail;

    return Container(
      child: Html(
        data: goodsDetails//注意这里是data，而不是child了！！！！
      ),
    );
  }
}

pages/details_page.dart

import 'package:flutter/material.dart';
import 'package:provide/provide.dart';
import '../provide/details_info.dart';
import './details_page/details_top_area.dart';
import './details_page/details_expain.dart';
import './details_page/details_tabbar.dart';
import './details_page/details_web.dart';

class DetailsPage extends StatelessWidget {
  final String goodsId;

  DetailsPage(this.goodsId);//flutter 1.2的最新的写法 构造函数

  @override
  Widget build(BuildContext context) {
 
    return Scaffold(
      appBar: AppBar(
        leading: IconButton(
          icon: Icon(Icons.arrow_back),
          onPressed: (){
            Navigator.pop(context);//返回上一个页面
          },
        ),
        title: Text('商品详细页'),
      ),
      body: FutureBuilder(
        future: _getBackInfo(context),
        builder: (context,snapshot){
          //判断是否有数据
          if(snapshot.hasData){
            //如果有数据返回一个Container
            return Container(
              child: ListView(
                children: <Widget>[
                  DetailsTopArea(),
                  DetailsExplain(),
                  DetailsTabbar(),
                  DetailsWeb()
                ],
              ),
            );
          }else{
            return Text('加载中......');//没有数据的情况
          }
        },
      ),
    );
  }

  Future _getBackInfo(BuildContext context) async{
    await Provide.value<DetailsInfoProvide>(context).getGoodsInfo(goodsId);
    //print('加载完成...........');
    return '完成加载';
  }

}
