In this article, you can learn about how to show tooltips in the Flutter DataGrid cells.

Initialize the SfDataGrid widget with all the required properties. To achieve this, you can wrap the Tooltip widget around the widget loaded in the DataGridCell and set the desired value in the Tooltip.message property within the DataGridSource.buildRow method.

class EmployeeDataSource extends DataGridSource {

 @override
 DataGridRowAdapter buildRow(DataGridRow row) {
    return DataGridRowAdapter(
        cells: row.getCells().map<Widget>((e) {
      return Tooltip(
        message: '${e.value}',
        child: Container(
          alignment: Alignment.center,
          padding: const EdgeInsets.all(8.0),
          child: Text(e.value.toString()),
        ),
      );
    }).toList());
  }
