小编Emm*_*cha的帖子

每当我尝试通过 git bash 或命令提示符在 flutter 中创建新项目时，我不断收到此错误Got socket error trying to find package cupertino_icons at https://pub.dartlang.org.我已将 flutter sdk 升级到最新版本，但仍然存在相同的问题。请问我如何解决这个问题。谢谢

我正在堆叠小部件，我希望它是可滚动的，所以我使用了一个列表视图，我收到了这个错误（constraints.hasBoundedHeight'：不是真正的颤动）我看到某处不能将列表视图放置在列表视图中，所以我将其更改为 Column但我仍然遇到同样的错误。下面是我的代码。谢谢。

ListView homeList(){
var listView = ListView(
  shrinkWrap: true,
  children: <Widget>[
    _imageSlider(),

    Padding(
      padding: EdgeInsets.only(top: 15.0, bottom: 15.0, left: 15.0),
      child: Text("Trending", style: TextStyle(color: Colors.white, fontSize: 15.0),),
    ),

   Container(
     child: FutureBuilder(
       future: _trendingListImages(),
         builder: (BuildContext context, AsyncSnapshot async){
           if(async.data == null){
           return ColorLoader3(
          radius: 20.0,
          dotRadius: 5.0,
           );
          }else{
            return ListView.builder(
                shrinkWrap: true,
                scrollDirection: Axis.horizontal,
                itemCount: async.data.length,
                itemBuilder: (BuildContext context, int position) {
                  return Column(
                    crossAxisAlignment: CrossAxisAlignment.center,
                    mainAxisSize: MainAxisSize.min,
                    children: <Widget>[
                      Card(
                        elevation: 18.0,
                        shape: RoundedRectangleBorder(
                            borderRadius: BorderRadius.all(Radius.circular(10.0))),
                        child: …

请问我如何使用颤振实现上图。一个带有文本的卡片视图，并将其放在水平的 listview.builder 中，以便用数据填充它。

  ListView homeList(){
var listView = ListView(
  shrinkWrap: true,
  children: <Widget>[
    _imageSlider(),

    Padding(
      padding: EdgeInsets.only(top: 15.0, bottom: 15.0, left: 15.0),
      child: Text("Trending", style: TextStyle(color: Colors.white, fontSize: 15.0),),
    ),

   Container(
     child: FutureBuilder(
       future: _trendingListImages(),
         builder: (BuildContext context, AsyncSnapshot async){
           if(async.data == null){
           return ColorLoader3(
          radius: 20.0,
          dotRadius: 5.0,
           );
          }else{
            return ListView.builder(
              shrinkWrap: true,
              scrollDirection: Axis.horizontal,
                itemCount: async.data.length,
                itemBuilder: (BuildContext context, int position){
                      return Card(
                        child: ListTile(
                          title:Image.network(
                                "http://image.tmdb.org/t/p/w500/"+async.data[position].backdropPath,),


                          subtitle: Text(async.data[position].title),
                        )
                      );
                }
            );
           }
         }
     ),
   ) …
