Futurebuilder（）在我的flutter应用程序中一次又一次地重建

Question

我是Flutter应用程序开发的新蜂。我正在开发Flutter应用程序。我的问题是，每当我由应用程序运行的ListView.builder（）未被执行并且FutureBuilder（）一次又一次地重建时，就像所有条件变为真并无限地执行一样，我已经尝试了许多方法，例如ListView.custom并且切换大小写，而不是每次我都得到相同结果时，是否可以解决此问题？

注意：我正在从Restful API中获取数据。

  @override
  Widget build(BuildContext context) {
    return ResponsiveBuilder(
      builder: (context,sizingInformation){
        return SafeArea(
          child: Scaffold(
            body: FutureBuilder(
              future: GalleryInformation().getGalleryList(widget.id),
              builder:(BuildContext context,AsyncSnapshot snapshot){
                if(snapshot.hasError){
                  return Container();
                }
                else if(snapshot.connectionState == ConnectionState.done){
                  var response = snapshot.data as List<Gallery>;
                  return ListView.builder(
                    itemCount: response.length,
                    itemBuilder: (context,index){
                       print(widget.id);
                      var gallery = response[index];
                      return Column(
                            children: <Widget>[
