最终代码

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 Provide<DetailsInfoProvide>(
      builder: (context,child,val){
        var isLeft=Provide.value<DetailsInfoProvide>(context).isLeft;
        if(isLeft){
          //详情页
            return Container(
                child: Html(
                  data: goodsDetails//注意这里是data，而不是child了！！！！
                ),
            );
        }else{
          return Container(
            width: ScreenUtil().setWidth(750),//和我们的页面等宽的
            padding: EdgeInsets.all(10.0),
            alignment: Alignment.center,//居中显示
            child: Text(‘暂时没有数据‘)
          );
        }
      },
    );
