【Flutter】Flutter异常：The following assertion was thrown during performResize(),SliverGeometry is not v

问题内容 SliverGeometry is not valid: The "layoutExtent" exceeds the "paintExtent"

这里的异常主要针对NestedScrollView 或者CustomScrollView 中 在listview中套入 EasyRefresh的时候出现的以上问题.

因为在嵌套的时候其实都有ROw或者column的存在.如果报错的,请在 EasyRefresh的外层套上一层Expanded.

因为我的listview加载的内容是通过FutureBuilder来获取加载的,所以我的做法是在FutureBuilder的外层套了Expanded

     Expanded(
              child: FutureBuilder(
                  future: controller.getcompanylistRequest(1, -1, -1, -1),
                  builder: _BuildFuture))


Widget _BuildFuture(context, AsyncSnapshot snapshot) {
    switch (snapshot.connectionState) {
      case ConnectionState.none:
        return Text('还没有开始网络请求');
      case ConnectionState.active:
        return Text('ConnectionState.active');
      case ConnectionState.waiting:
        return Center(
          child: CircularProgressIndicator(),
        );
      case ConnectionState.done:
        if (snapshot.hasError)
          return Text('Error: 获取数据失败,请检查网络后重试!${snapshot.error}');
        return _listviewbuilder(context);
    }
  }

  var pagecount = 1;
  Widget _listviewbuilder(BuildContext context) {
    return Container(
      child: EasyRefresh(
        enableControlFinishLoad: false,
        controller: escontroller,
        child: Obx(() => ListView.builder(
              padding: EdgeInsets.zero,
              itemCount: controller.companylist.length,
              physics: NeverScrollableScrollPhysics(),
              shrinkWrap: true,
              itemBuilder: (context, index) {
                return //Text("$index");
                    CompanyListViewModel(//我自定义的widget
                  controller.companylist[index].logo,
                  controller.companylist[index].comname,
                  controller.companylist[index].companywelfare,
                  controller.companylist[index].adress,
                  controller.companylist[index].compnayscaleindex,
                  controller.companylist[index].comkindindex,
                );
              },
            )),
        onLoad: () async {
          pagecount++;
          await GetRequest("${ApiConstants.baseApiStruct['companylist']}" +
                  '$pagecount' +
                  '&industryid=' +
                  '${controller.industryid.value}' +
                  '&kindid=' +
                  '${controller.kindid.value}' +
                  '&ayscaleid=' +
                  '${controller.ayscaleid.value}')
              .then((value) {
            String data =
                '{"code":"1","message":"成功","data":' + value.toString() + '}';
            var datanew = json.decode(data);
            CompanyListModel _hotworklist = CompanyListModel.fromJson(datanew);
            _hotworklist.data!.forEach((element) {
              controller.companylist.add(element);
            });
            print(controller.companylist[0].id);
          });
        },
      ),
    );
