隐藏颤振数据表中的复选框

Question

我有一个数据表，我需要在其中编辑数量。我正在检测使用下面的代码选择了哪一行，该代码工作正常，但我想隐藏复选框列

关于如何在没有复选框列的情况下保持当前行为有什么建议吗？

@override
Widget build(BuildContext context) {
return Scaffold(
    appBar: AppBar(
        title: Text(
          "Sample",
          style: TextStyle(color: Colors.white),
        ),
    body: Column(children: <Widget>[
      DataTable(
        sortAscending: true,
        columns: <DataColumn>[
          DataColumn(
            label: Text('Product name'),
          ),
          DataColumn(
            label: Text('Product Quantity'),
          ),
        ],
        rows: items
            .map(
              (itemRow) => DataRow(
                onSelectChanged: (bool selected) {
                  if (selected) {
                    //'row-selected: ${itemRow.index}'
                  }
                },
                cells: [
                  DataCell(
                    Text(itemRow.itemName),
                    showEditIcon: false,
                    placeholder: false,
                  ),
                  DataCell(
                    Text(itemRow.itemQuantity),
                    showEditIcon: true,
                    placeholder: false,
                    //onTap: _getSelectedRowInfo,
                  ),
                ],
              ),
            )
            .toList(),
      )
    ]),
    bottomNavigationBar: BottomNavigationBar(
      items: const <BottomNavigationBarItem>[
        BottomNavigationBarItem(
          icon: Icon(Icons.home),
          title: Text('Home'),
        ),
      ],
      currentIndex: _selectedIndex,
      selectedItemColor: Colors.amber[800],
      onTap: _onItemTapped,
    ));
  }
}

如果您位于主频道而不是稳定频道，则有可能。

您只需添加一个为DataTablefalse 的属性showCheckboxColumn。

编辑后的完整代码将是

@override
Widget build(BuildContext context) {
return Scaffold(
    appBar: AppBar(
        title: Text(
          "Sample",
          style: TextStyle(color: Colors.white),
        ),
    body: Column(children: <Widget>[
      DataTable(
        showCheckboxColumn: false,
        sortAscending: true,
        columns: <DataColumn>[
          DataColumn(
            label: Text('Product name'),
          ),
          DataColumn(
            label: Text('Product Quantity'),
          ),
        ],
        rows: items
            .map(
              (itemRow) => DataRow(
                onSelectChanged: (bool selected) {
                  if (selected) {
                    //'row-selected: ${itemRow.index}'
                  }
                },
                cells: [
                  DataCell(
                    Text(itemRow.itemName),
                    showEditIcon: false,
                    placeholder: false,
                  ),
                  DataCell(
                    Text(itemRow.itemQuantity),
                    showEditIcon: true,
                    placeholder: false,
                    //onTap: _getSelectedRowInfo,
                  ),
                ],
              ),
            )
            .toList(),
      )
    ]),
    bottomNavigationBar: BottomNavigationBar(
      items: const <BottomNavigationBarItem>[
        BottomNavigationBarItem(
          icon: Icon(Icons.home),
          title: Text('Home'),
        ),
      ],
      currentIndex: _selectedIndex,
      selectedItemColor: Colors.amber[800],
      onTap: _onItemTapped,
    ));
  }
}

一些 flutter 开发人员不建议更改为 master，但如果没有问题，您可以使用以下命令更改它： flutter channel master flutter upgrade
