Dynamically adjust the row height based on the content of cells in a Flutter DataGrid.

In this article, We will explain how to modify the row heights in a Flutter DataGrid to ensure that all the content is adequately displayed, regardless of its length.

Initialize the SfDataGrid widget with all the required properties. Set the onQueryRowHeight callback to handle row height adjustments dynamically. Use the RowHeightDetails.getIntrinsicRowHeight method to compute the suitable row height by considering the content of the cells in that row. To obtain the intrinsic height for a specific row, you can provide details.rowIndex as an argument to the getIntrinsicRowHeight method.

@override
 Widget build(BuildContext context) {
   return Scaffold(
     appBar: AppBar(
       title: const Text('Syncfusion Flutter DataGrid'),
     ),
     body: SfDataGrid(
       source: employeeDataSource,
       columnWidthMode: ColumnWidthMode.fill,
       onQueryRowHeight: (details) {
         return details.getIntrinsicRowHeight(details.rowIndex);
       },
       columns: <GridColumn>[
         GridColumn(
             columnName: 'id',
             label: Container(
                 padding: EdgeInsets.all(16.0),
                 alignment: Alignment.center,
                 child: Text(
                   'ID',
                   softWrap: true,
                 ))),
         GridColumn(
             columnName: 'name',
             label: Container(
                 padding: EdgeInsets.all(8.0),
                 alignment: Alignment.center,
                 child: Text(
                   'Name of the Employee ',
                   softWrap: true,
                 ))),
         GridColumn(
             columnName: 'designation',
             label: Container(
                 padding: EdgeInsets.all(8.0),
                 alignment: Alignment.center,
                 child: Text(
                   'Role of the Employee',
                   softWrap: true,
                 ))),
         GridColumn(
             columnName: 'salary',
             label: Container(
                 padding: EdgeInsets.all(8.0),
                 alignment: Alignment.center,
                 child: Text(
                   'Salary',
                   softWrap: true,
                 ))),
       ],
     ),
   );
 }
