child view can not be Container

[lucasjinreal]

The child parameter can not be Container:

return new SmartRefresher(
        enablePullDown: true,
        enablePullUp: true,
        // refreshMode: this.refreshing,
        // loadMode: this.loading,
        onRefresh: _onRefresh,
        // headerBuilder: _buildHeader,
        // onOffsetChange: _onOffsetCallback,
        child: new Container(
            color: Colors.white,
            child: new Column(
              children: <Widget>[
                // headBannerSection,
                carouselBanner,
                _buildCategorySection(context),
                _buildListViewContent(),
              ],
            )));
  }

This gives an error.

Yes,I have modified the latest version to be ScrollView type only, because listView can not cache item without doing so. You can wrap it in ListView too

@peng8350 Thanks for your reply, I am previously using a ListView contains all my sections, however there was an error:

[VERBOSE-2:dart_error.cc(16)] Unhandled exception:

Here is my codes:

@override
  Widget build(BuildContext context) {
    return new SmartRefresher(
        enablePullDown: true,
        enablePullUp: true,
        // refreshMode: this.refreshing,
        // loadMode: this.loading,
        controller: _refreshController,
        onRefresh: _onRefresh,
        // headerBuilder: _buildHeader,
        // onOffsetChange: _onOffsetCallback,
        // child: new Container(
        //     color: Colors.white,
        //     child: new Column(
        //       children: <Widget>[
        //         // headBannerSection,
        //         carouselBanner,
        //         _buildCategorySection(context),
        //         _buildListViewContent(),
        //       ],
        //     )));
        child: new ListView(
          children: <Widget>[
            carouselBanner,
                _buildCategorySection(context),
                _buildListViewContent(),
          ],
        )
      );
  }

The comment are the previous code, any suggestions?

The problem is that there are no default headerBuilder and footerBuilder inside, you only need to add the two attributes. I'll give it a default indicator in the next version
