Introduction

Syncfusion Flutter offers a rich set of UI components—grids, charts, calendars, and more—that accelerate development of data-driven mobile and web applications. In this intermediate tutorial, you’ll learn how to integrate Syncfusion’s latest Flutter widgets into your app. We’ll cover setup, implementing a DataGrid, adding charts for visualization, and customizing themes. By the end, you’ll have hands-on experience using syncfusion flutter packages to build a polished interface.

Getting Started with Syncfusion Flutter

Before writing UI code, add Syncfusion to your Flutter project:

dependencies:
  flutter:
    sdk: flutter
  syncfusion_flutter_datagrid: ^21.1.56
  syncfusion_flutter_charts

After saving pubspec.yaml, run flutter pub get. Next, initialize the license in your main.dart (required for production apps):

import 'package:syncfusion_flutter_core/core.dart';

void main() {
  SyncfusionLicense.registerLicense("YOUR_LICENSE_KEY");
  runApp(MyApp());
}

This setup ensures both the DataGrid and Charts widgets load correctly. If you’re exploring these controls for evaluation, omit the license and you’ll see the trial watermark.

Integrating the DataGrid Widget

The Syncfusion DataGrid is ideal for displaying tabular data with sorting, pagination, and editing. Here’s how to bind it to a simple data source:

class Order {
  Order(this.id, this.customer, this.amount);
  final int id;
  final String customer;
  final double amount;
}

class OrderDataSource extends DataGridSource {
  OrderDataSource(this.orders) {
    buildDataGridRows();
  }

  List<DataGridRow> dataGridRows = [];
  final List<Order> orders;

  void buildDataGridRows() {
    dataGridRows = orders.map<DataGridRow>((order) {
      return DataGridRow(cells: [
        DataGridCell<int>(columnName: 'ID', value: order.id),
        DataGridCell<String>(columnName: 'Customer', value: order.customer),
        DataGridCell<double>(columnName: 'Amount', value: order.amount),
      ]);
    }).toList();
  }

  @override
  List<DataGridRow> get rows => dataGridRows;

  @override
  DataGridRowAdapter buildRow(DataGridRow row) {
    return DataGridRowAdapter(cells: row.getCells().map<Widget>((cell) {
      return Container(
        padding: EdgeInsets.all(8),
        alignment: Alignment.center,
        child: Text(cell.value.toString()),
      );
    }).toList());
  }
}

Then place the grid in your widget tree:

SfDataGrid(
  source: OrderDataSource(sampleOrders),
  columns: <GridColumn>[
    GridColumn(columnName: 'ID', label: Text('ID')),
    GridColumn(columnName: 'Customer', label: Text('Customer')),
    GridColumn(columnName: 'Amount', label: Text('Amount')),
  ],
  allowSorting: true,
  allowEditing: false,
);

This code snippet integrates Syncfusion DataGrid into your layout. You can extend features with editing, filtering, and paging by toggling its API flags.

Adding Charts for Data Visualization

Visualizing metrics is easy with syncfusion flutter charts. Here’s an example of a simple column chart:

class SalesData {
  SalesData(this.year, this.sales);
  final String year;
  final double sales;
}

SfCartesianChart(
  primaryXAxis: CategoryAxis(),
  title: ChartTitle(text: 'Annual Sales'),
  legend: Legend(isVisible: true),
  tooltipBehavior: TooltipBehavior(enable: true),
  series: <ChartSeries<SalesData, String>>[
    ColumnSeries<SalesData, String>(
      dataSource: <SalesData>[
        SalesData('2018', 35),
        SalesData('2019', 28),
        SalesData('2020', 34),
        SalesData('2021', 52),
      ],
      xValueMapper: (SalesData data, _) => data.year,
      yValueMapper: (SalesData data, _) => data.sales,
      name: 'Sales',
      color: Colors.blue,
    )
  ],
)

Place this widget anywhere in your Scaffold body. The chart will render interactively with tooltips enabled. Syncfusion widgets support dozens of chart types, including line, area, pie, and more. Simply swap ColumnSeries with the series type you need.

Customizing Themes and Styles

Syncfusion flutter widgets respect Flutter’s theming, allowing you to integrate UI controls seamlessly with your brand style:

ThemeData(
  primarySwatch: Colors.teal,
  textTheme: TextTheme(bodyText2: TextStyle(color: Colors.grey[800])),
  visualDensity: VisualDensity.adaptivePlatformDensity,
  dataGridTheme: DataGridThemeData(
    headerColor: Colors.teal,
    rowHoverColor: Colors.teal[50],
  ),
  chartTheme: ChartThemeData(
    axisLabelColor: Colors.teal[700],
    tooltipColor: Colors.tealAccent,
  ),
);

Wrap your MaterialApp in this custom ThemeData. You can further tune grid borders, chart axes, legends, and markers via widget-level properties. Syncfusion widgets expose rich style APIs, giving you pixel-level control.

Vibe Studio

Vibe Studio, powered by Steve’s advanced AI agents, is a revolutionary no-code, conversational platform that empowers users to quickly and efficiently create full-stack Flutter applications integrated seamlessly with Firebase backend services. Ideal for solo founders, startups, and agile engineering teams, Vibe Studio allows users to visually manage and deploy Flutter apps, greatly accelerating the development process. The intuitive conversational interface simplifies complex development tasks, making app creation accessible even for non-coders.

Conclusion

By integrating Syncfusion Flutter widgets—such as DataGrid and Charts—into your app, you can deliver enterprise-grade interfaces with minimal boilerplate. You now have the skills to set up syncfusion flutter packages, bind data sources, implement interactive charts, and apply custom themes.

With these tools in your toolkit, you can prototype, iterate, and ship Flutter apps faster than ever before—leveraging both syncfusion widgets and no-code platforms to achieve maximum productivity.
