Code example

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

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

@override
    Widget build(BuildContext context) {
        final List<ChartData> chartData = [
            ChartData('David', 25),
            ChartData('Steve', 38),
            ChartData('Jack', 34),
            ChartData('Others', 52)
        ];
        return Scaffold(
            body: Center(
                child: Container(
                    child: SfCircularChart(
                        series: <CircularSeries>[
                            // Render pie chart
                            PieSeries<ChartData, String>(
                                dataSource: chartData,
                                pointColorMapper:(ChartData data, _) => data.color,
                                xValueMapper: (ChartData data, _) => data.x,
                                yValueMapper: (ChartData data, _) => data.y
                            )
                        ]
                    )
                )
            )
        );
    }

    class ChartData {
        ChartData(this.x, this.y, [this.color]);
        final String x;
        final double y;
        final Color color;
    }
