Code example

Easily get started with the Flutter Bar Chart using a few simple lines of DART code example as demonstrated below,

import 'package:flutter/material.dart';
import 'package:syncfusion_flutter_charts/charts.dart';

void main() {
  return runApp(_ChartApp());

class _ChartApp extends StatelessWidget {
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(primarySwatch: Colors.blue),
      home: _MyHomePage(),

class _MyHomePage extends StatefulWidget {
  // ignore: prefer_const_constructors_in_immutables
  _MyHomePage({Key? key}) : super(key: key);

  _MyHomePageState createState() => _MyHomePageState();

class _MyHomePageState extends State<_MyHomePage> {
  late List<_ChartData> data;
  late TooltipBehavior _tooltip;

  void initState() {
    data = [
      _ChartData('CHN', 12),
      _ChartData('GER', 15),
      _ChartData('RUS', 30),
      _ChartData('BRZ', 6.4),
      _ChartData('IND', 14)
    _tooltip = TooltipBehavior(enable: true);

  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: const Text('Syncfusion Flutter chart'),
        body: SfCartesianChart(
            primaryXAxis: CategoryAxis(),
            primaryYAxis: NumericAxis(minimum: 0, maximum: 40, interval: 10),
            tooltipBehavior: _tooltip,
            series: <CartesianSeries<_ChartData, String>>[
              BarSeries<_ChartData, String>(
                  dataSource: data,
                  xValueMapper: (_ChartData data, _) => data.x,
                  yValueMapper: (_ChartData data, _) => data.y,
                  name: 'Gold',
                  color: Color.fromRGBO(8, 142, 255, 1))

class _ChartData {
  _ChartData(this.x, this.y);

  final String x;
  final double y;
