How to copy cell content to clipboard using a button in Flutter DataTable (SfDataGrid)?.

4 mins read

In this article, we will show you how to copy cell content to clipboard using a button in Flutter DataTable.

Initialize the SfDataGrid with the necessary properties. The DataGridSource.rows property provides access to all rows in the grid. To copy the data, iterate through each row in DataGridSource.rows and extract the values of each cell. Format the data as a tab-separated string to maintain the table structure. Finally, use Flutter’s Clipboard.setData method to copy the formatted string to the clipboard, allowing them to paste the copied content anywhere.

void copyEntireGrid(EmployeeDataSource dataSource) {
    String copiedData = '';

    // Extract column headers
    copiedData += 'ID\tName\tDesignation\tSalary\n';

    // Extract row data
    copiedData += dataSource.rows
        .map((row) {
          return row.getCells().map((cell) => cell.value.toString()).join('\t');
        })
        .join('\n');

    Clipboard.setData(ClipboardData(text: copiedData));
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Syncfusion Flutter DataGrid'),
        actions: [
          IconButton(
            icon: const Icon(Icons.copy),
            tooltip: 'Copy DataGrid',
            onPressed: () {
              copyEntireGrid(employeeDataSource);
            },
          ),
        ],
      ),
      body: SfDataGrid(
        source: employeeDataSource,
        shrinkWrapRows: true,
        columnWidthMode: ColumnWidthMode.fill,
        columns: <GridColumn>[
          GridColumn(
            columnName: 'id',
            label: Container(
              padding: const EdgeInsets.all(16.0),
              alignment: Alignment.center,
              child: const Text('ID'),
            ),
          ),
          GridColumn(
            columnName: 'name',
            label: Container(
              padding: const EdgeInsets.all(8.0),
              alignment: Alignment.center,
              child: const Text('Name'),
            ),
          ),
          GridColumn(
            columnName: 'designation',
            label: Container(
              padding: const EdgeInsets.all(8.0),
              alignment: Alignment.center,
              child: const Text('Designation', overflow: TextOverflow.ellipsis),
            ),
          ),
          GridColumn(
            columnName: 'salary',
            label: Container(
              padding: const EdgeInsets.all(8.0),
              alignment: Alignment.center,
              child: const Text('Salary'),
            ),
          ),
        ],
      ),
    );
  }
