How to Get the Entire Row Details in Flutter DataGrid?
In this article, you can learn about how to get the entire row details when tapping the respective row cells in Flutter DataGrid
STEP 1: Create a data source class by extending DataGridSource for mapping data to the SfDataGrid.
class EmployeeDataSource extends DataGridSource {
EmployeeDataSource(List<Employee> employees) {
buildDataGridRow(employees);
}
void buildDataGridRow(List<Employee> employeeData) {
dataGridRow = employeeData.map<DataGridRow>((employee) {
return DataGridRow(cells: [
DataGridCell<int>(columnName: 'id', value: employee.id),
DataGridCell<String>(columnName: 'name', value: employee.name),
DataGridCell<String>(
columnName: 'designation', value: employee.designation),
DataGridCell<int>(columnName: 'salary', value: employee.salary),
]);
}).toList();
}
List<DataGridRow> dataGridRow = <DataGridRow>[];
@override
List<DataGridRow> get rows => dataGridRow.isEmpty ? [] : dataGridRow;
@override
DataGridRowAdapter? buildRow(DataGridRow row) {
return DataGridRowAdapter(
cells: row.getCells().map<Widget>((dataGridCell) {
return Container(
alignment: Alignment.center,
padding: const EdgeInsets.symmetric(horizontal: 8.0),
child: SelectableText(dataGridCell.value.toString()),
);
}).toList());
}
}
STEP 2: Initialize the SfDataGrid widget with all the required properties. When you tap the row, you will get the row index in the onCellTap callback. Then, you can fetch the respective row data from the DataGridSource.effectiveRows. Here, the respective row details will be shown in the AlertDialog with a onCellTap.
List<Employee> _employees = <Employee>[];
late EmployeeDataSource _employeeDataSource;
@override
void initState() {
super.initState();
_employees = getEmployeeData();
_employeeDataSource = EmployeeDataSource(_employees);
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Flutter SfDataGrid'),
),
body: SfDataGrid(
source: _employeeDataSource,
columns: getColumns,
columnWidthMode: ColumnWidthMode.fill,
allowSorting: true,
onCellTap: ((details) {
if (details.rowColumnIndex.rowIndex != 0) {
int selectedRowIndex = details.rowColumnIndex.rowIndex - 1;
var row =
_employeeDataSource.effectiveRows.elementAt(selectedRowIndex);
showDialog(
context: context,
builder: (context) => AlertDialog(
shape: const RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(32.0))),
content: SizedBox(
height: 300,
width: 300,
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Row(children: [
const Text('Employee ID'),
const Padding(
padding:
EdgeInsets.symmetric(horizontal: 25)),
const Text(':'),
const Padding(
padding:
EdgeInsets.symmetric(horizontal: 10)),
Text(row.getCells()[0].value.toString()),
]),
Row(children: [
const Text('Employee Name'),
const Padding(
padding:
EdgeInsets.symmetric(horizontal: 10)),
const Text(':'),
const Padding(
padding:
EdgeInsets.symmetric(horizontal: 10)),
Text(row.getCells()[1].value.toString()),
]),
Row(children: [
const Text('Designation'),
const Padding(
padding:
EdgeInsets.symmetric(horizontal: 25)),
const Text(':'),
const Padding(
padding:
EdgeInsets.symmetric(horizontal: 10)),
Text(row.getCells()[2].value.toString()),
]),
Row(children: [
const Text('Salary'),
const Padding(
padding:
EdgeInsets.symmetric(horizontal: 45)),
const Text(':'),
const Padding(
padding:
EdgeInsets.symmetric(horizontal: 10)),
Text(row.getCells()[3].value.toString()),
]),
SizedBox(
width: 300,
child: ElevatedButton(
onPressed: () {
Navigator.pop(context);
},
child: const Text("OK")),
)
]),
)));
}
}),
),
);
}
