How to Auto-Resize Row Height After Data Edit in Flutter DataTable?

In this article, we will show you how to automatically resize the row height after editing data in a Flutter DataTable.

Initialize the SfDataGrid widget with all the required properties. You can achieve this by calling the DataGridController.refreshRow method with the corresponding row index and setting the recalculateRowHeight property to true within the DataGridSource.onCellSubmit method.

  DataGridController dataGridController = DataGridController();
 
  @override
  void initState() {
    super.initState();
    _employees = getEmployeeData();
    _employeeDataSource = EmployeeDataSource(_employees, dataGridController);
  }
 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Syncfusion Flutter DataGrid')),
      body: SfDataGrid(
        controller: dataGridController,
        source: _employeeDataSource,
        columns: getColumns,
        allowEditing: true,
        navigationMode: GridNavigationMode.cell,
        selectionMode: SelectionMode.single,
        onQueryRowHeight: (details) {
          return details.getIntrinsicRowHeight(details.rowIndex);
        },
      ),
    );
  }
 
class EmployeeDataSource extends DataGridSource {
  EmployeeDataSource(this.employees, this.dataGridController) {
    dataGridRows = employees
        .map<DataGridRow>((dataGridRow) => dataGridRow.getDataGridRow())
        .toList();
  }
 
  DataGridController dataGridController;
…
 
 @override
  void onCellSubmit(DataGridRow dataGridRow, RowColumnIndex rowColumnIndex,
      GridColumn column) {
…
 
    dataGridController.refreshRow(rowColumnIndex.rowIndex,
        recalculateRowHeight: true);
  }
}
