如何在TabBarView中集成SliverGrid？

Question

我正在嘗試使用CustomScrollView和TabBar，但不確定為什么我的實現無法正常工作。

我將TabBar包裹在SliverToBoxAdapter中，仍然沒有運氣。 以前，我嘗試過GridView，但是這樣做會產生不必要的行為。

Widget build(BuildContext context) {
    return Scaffold(
        body: CustomScrollView(
      slivers: <Widget>[
        SliverToBoxAdapter(
          child: CarouselSlider(
            items: imgList.map((i) {
              return Builder(
                builder: (BuildContext context) {
                  return Container(
                    child: ClipRRect(
                      borderRadius: BorderRadius.all(Radius.circular(30.0)),
                      child: Image.network(
                        i,
                        fit: BoxFit.cover,
                        width: 1000.0,
                      ),
                    ),
                  );
                },
              );
            }).toList(),
            viewportFraction: 1.0,
            height: 300.0,
          ),
        ),
        SliverToBoxAdapter(
          child: Container(
            margin: EdgeInsets.all(10.0),
            child: Padding(
              padding: EdgeInsets.only(top: 10.0),
              child: Container(
                margin: EdgeInsets.only(left: 15.0, bottom: 15.0),
                child: Row(
                  mainAxisAlignment: MainAxisAlignment.start,
                  children: <Widget>[
                    Container(
                      child: CircleAvatar(
                        backgroundImage: AssetImage(
                            'assets/images/cut1.png'), // put image here
                        radius: 50,
                      ),
                    ),
                    Expanded(
                        child: Column(
                      children: <Widget>[
                        Text('Frank Palma',
                            style: TextStyle(
                              fontSize: 25,
                              fontWeight: FontWeight.bold,
                            )),
                        IconTheme(
                          data: IconThemeData(
                            color: Colors.amber,
                            size: 25,
                          ),
                          child: StarDisplay(value: 4),
                        ),
                        Text(
                          '546 Cuts',
                        ),
                      ],
                    ))
                  ],
                ),
              ),
            ),
          ),
        ),
        SliverToBoxAdapter(
            child: TabBar(
              controller: _tabcontroller,
              unselectedLabelColor: Colors.blue,
              indicator: BubbleTabIndicator(
                  indicatorHeight: 25.0,
                  indicatorColor: Colors.blue,
                  tabBarIndicatorSize: TabBarIndicatorSize.tab),
              tabs: <Widget>[
                Tab(icon: Icon(Icons.location_on)),
                Tab(icon: Icon(Icons.calendar_view_day)),
                Tab(icon: Icon(Icons.picture_in_picture))
              ],
            ),
        ),
        SliverToBoxAdapter(
          child: TabBarView(
            controller: _tabcontroller,
            children: [
              Center(
                  child: Card(

                      onSelectedRangeChange: (range) =>
                          print("Range is ${range.item1}, ${range.item2}"),

              SliverGrid(

                    crossAxisCount: 3),

            ],
          ),
        )
      ],
    ));
  }

Answer 1

當嵌套兩個可滾動小部件時，我需要限制內部小部件的可滾動性。 當我遇到此問題時，解決方案是將代碼添加到內部小部件中：

ShrinkWrap: true, // Solve the problem of infinite height

Physics: NeverScrollable ScrollPhysics (), // Disable Sliding Events
