在网上很难找到一些关于扑的资料，你是我最后的机会啊
在我的示例中，我创建了一个包含一些数据的简单网格。
因此，我想在flutter中使用复选框和SFDataGrid，我的目标是：

• 选择行
• 如果选择了行，则获取数据
• 点击按钮并显示所选数据

import 'package:syncfusion_flutter_datagrid/datagrid.dart';

class CheckboxColumn extends StatefulWidget {
  const CheckboxColumn({Key? key}) : super(key: key);

  @override
  _CheckboxColumnState createState() => _CheckboxColumnState();
}

class _CheckboxColumnState extends State<CheckboxColumn> {
  late EmployeeDataSource _employeeDataSource;
  List<Employee> _employees = <Employee>[];

  @override
  void initState() {
    super.initState();
    _employees = getEmployeeData();
    _employeeDataSource = EmployeeDataSource(employees: _employees);
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Syncfusion Flutter DataGrid')),
      body: SfDataGrid(
          source: _employeeDataSource,
          showCheckboxColumn: true,
          checkboxColumnSettings: DataGridCheckboxColumnSettings(
            backgroundColor: Color.fromARGB(255, 212, 0, 0),
          ),
          selectionMode: SelectionMode.multiple,
          columnWidthMode: ColumnWidthMode.fill,
          columns: <GridColumn>[
            GridColumn(
                columnName: 'id',
                label: Container(
                    padding: const EdgeInsets.symmetric(horizontal: 16.0),
                    alignment: Alignment.centerRight,
                    child: const Text('ID'))),
            GridColumn(
                columnName: 'name',
                label: Container(
                    padding: const EdgeInsets.symmetric(horizontal: 16.0),
                    alignment: Alignment.centerLeft,
                    child: const Text('Name'))),
            GridColumn(
                columnName: 'designation',
                label: Container(
                    padding: const EdgeInsets.symmetric(horizontal: 16.0),
                    alignment: Alignment.centerLeft,
                    child: const Text('Designation',
                        overflow: TextOverflow.ellipsis))),
            GridColumn(
                columnName: 'salary',
                label: Container(
                    padding: const EdgeInsets.symmetric(horizontal: 16.0),
                    alignment: Alignment.centerRight,
                    child: const Text('Salary')))
          ]),
    );
  }
}

class EmployeeDataSource extends DataGridSource {
  EmployeeDataSource({required List<Employee> employees}) {
    dataGridRows = employees
        .map<DataGridRow>((dataGridRow) => DataGridRow(cells: [
              DataGridCell<int>(columnName: 'id', value: dataGridRow.id),
              DataGridCell<String>(columnName: 'name', value: dataGridRow.name),

              DataGridCell<int>(
                  columnName: 'salary', value: dataGridRow.salary),
            ]))
        .toList();
  }

  List<DataGridRow> dataGridRows = [];

  @override
  List<DataGridRow> get rows => dataGridRows;

  @override
  DataGridRowAdapter? buildRow(DataGridRow row) {
    return DataGridRowAdapter(
        cells: row.getCells().map<Widget>((dataGridCell) {
      return Container(
          alignment: (dataGridCell.columnName == 'id' ||
                  dataGridCell.columnName == 'salary')
              ? Alignment.centerRight
              : Alignment.centerLeft,
          padding: const EdgeInsets.symmetric(horizontal: 16.0),
          child: Text(

            overflow: TextOverflow.ellipsis,
          ));
    }).toList());
  }
}

class Employee {
  Employee(this.id, this.name, this.designation, this.salary);
  int id;
  String name;
  String designation;
  int salary;
}

List<Employee> getEmployeeData() {
  return [
    Employee(10001, 'James', 'Project Lead', 20000),
    Employee(10002, 'Kathryn', 'Manager', 30000),
    Employee(10003, 'Lara', 'Developer', 15000),

  ];
}
