flutter - 消除小部件之间的间隙

Question

我想缩小列表之间的距离，但是它不起作用。我唯一的选择是扩大差距:Sizedbox，spacer，divider

码:

body: Container(
        child: Column(
          children: <Widget>[
            _mainList(Icon(Icons.cached), "Erste", "21:13 pm"),
            _mainList(Icon(Icons.cached), "Zweite", "21:13 pm"),
            _mainList(Icon(Icons.cached), "Dritte", "21:13 pm"),
            _mainList(Icon(Icons.cached), "Vierte", "21:13 pm"),
          ]
        )
  )

  Widget _mainList(Icon symbol, String name, String time){
    return Padding(
      padding: const EdgeInsets.symmetric(horizontal: 30),
      child: ListTile(
        leading: symbol,
        title: Text(name, textScaleFactor: 1.2),
        trailing: Text(time, textScaleFactor: 1.3),
      ),
    );
  }

Answer 1

class MyWidget extends StatelessWidget {
  final List<String> _names = ["Erste","Zweite","Dritte","Vierte"];
  final List<String> _dates = ["21:13 pm","21:13 pm","21:13 pm","21:13 pm"];
  @override
  Widget build(BuildContext context) {
    return Container(
        child: ListView.builder(
          shrinkWrap: true,
          itemBuilder: (BuildContext context, int index){
            return ListTile(
            contentPadding: EdgeInsets.symmetric(vertical:0.0),
            title: Text(_names[index]),
            leading: Icon(Icons.cached),
            trailing: Text(_dates[index]),
            );
          }
        )
    );
  }
