如何在flutter中删除listview.builder中自定义小部件和适合小部件之间的空格

Question

我正在制作一个带有颤振的纸牌游戏。 我想在游戏桌上以连续的顺序展示我的牌。 我为卡片制作了一个自定义小部件，并将它们放在 listview.builder 中。 卡片之间出现空间并且卡片不适合屏幕。 我在互联网上搜索了这个问题，但没有解决。 我的错在哪里？ 你能帮助我吗？

CardViewWidget：

Widget cardViewWidget(PlayingCard card) {
return Container(
  height: 80.0,
  width: MediaQuery.of(context).size.width / 5,
  color: Colors.red,
  child: Column(
    children: <Widget>[
      Text(
        _returnAssetUrl(card),
        style: TextStyle(fontSize: 15.0),
      ),
    ],
  ),
);}

建造：

Widget build(BuildContext context) {
return Scaffold(
  body: Container(
    child: Column(
      children: <Widget>[
        Container(
          child: Column(
            children: <Widget>[
              Text(
                oppoHand[0].cardType.toString() +
                    oppoHand[0].cardSuit.toString(),
                style: TextStyle(fontSize: 20.0),
              ),
              Text(
                oppoHand[1].cardType.toString(),
                style: TextStyle(fontSize: 20.0),
              ),
              Text(
                oppoHand[2].cardType.toString(),
                style: TextStyle(fontSize: 20.0),
              ),
              Text(
                oppoHand[3].cardType.toString(),
                style: TextStyle(fontSize: 20.0),
              ),
              Text(
                oppoHand[4].cardType.toString(),
                style: TextStyle(fontSize: 20.0),
              ),
            ],
          ),
        ),
        Container(
          child: Text("Score: " + oppoScore.toString()),
        ),
        Container(
          child: Column(children: <Widget>[
            ListView.builder(
              shrinkWrap: true,
              itemCount: groundDeck.length,
              itemBuilder: (BuildContext context, int index) {
                return Text(groundDeck[index].cardType.toString());
              },
            ),
          ]),
        ),
        Container(
          child: Text("Score: " + myScore.toString()),
        ),
        Container(
          height: 100.0,
          width: MediaQuery.of(context).size.width,
          child: Row(
            children: <Widget>[
              ListView.builder(
                  scrollDirection: Axis.horizontal,
                  shrinkWrap: true,
                  itemCount: myHand.length,
                  itemBuilder: (BuildContext context, int index) {
                    return FlatButton(
                      onPressed: () {
                        setState(() {
                          _clickedCard(index);
                        });
                      },
                      child: cardViewWidget(myHand[index]),
                    );
                  }),
            ],
          ),
        ),
      ],
    ),
  ),
);}}
