How can I right align each column in the Flutter DataTable?

How can I right align each DataCell in the Flutter DataTable?

For example, in this case, how can I have all the numbers aligned to the right?

Widget build(BuildContext context) {
  return DataTable(
    columns: const <DataColumn>[
      DataColumn(
        label: Expanded(child: Text('Name', style: TextStyle(fontStyle: FontStyle.italic))),
      ),
      DataColumn(
        label: Expanded(child: Text('Number', style: TextStyle(fontStyle: FontStyle.italic))),
      ),
    ],
    rows: const <DataRow>[
      DataRow(
        cells: <DataCell>[
          DataCell(Text('Sarah')),
          DataCell(Text('1')),
        ],
      ),
      DataRow(
        cells: <DataCell>[
          DataCell(Text('Janine')),
          DataCell(Text('100')),
        ],
      ),
      DataRow(
        cells: <DataCell>[
          DataCell(Text('William')),
          DataCell(Text('1000')),
        ],
      ),
    ],
  );
}

Thanks in advance!

You can just use the numeric property.

@immutable
class DataColumn {
  const DataColumn({
    required this.label,
    this.tooltip,
    this.numeric = false,
    this.onSort,
  }) : assert(label != null);


  /// Whether this column represents numeric data or not.
  ///
  /// The contents of cells of columns containing numeric data are
  /// right-aligned.
  final bool numeric;
  ///...
}
