Just use this plugin pie_chart: ^5.1.0
import 'package:pie_chart/pie_chart.dart';
Map<String, double> dataMap = {
"Flutter": 5,
"React": 3,
"Xamarin": 2,
"Ionic": 2,
};
PieChart(
dataMap: dataMap,
animationDuration: Duration(milliseconds: 800),
chartLegendSpacing: 32,
chartRadius: MediaQuery.of(context).size.width / 3.2,
colorList: colorList,
initialAngleInDegree: 0,
chartType: ChartType.ring,
ringStrokeWidth: 32,
centerText: "HYBRID",
legendOptions: LegendOptions(
showLegendsInRow: false,
legendPosition: LegendPosition.right,
showLegends: true,
legendShape: _BoxShape.circle,
legendTextStyle: TextStyle(
fontWeight: FontWeight.bold,
),
),
chartValuesOptions: ChartValuesOptions(
showChartValueBackground: true,
showChartValues: true,
showChartValuesInPercentage: false,
showChartValuesOutside: false,
decimalPlaces: 1,
),
// gradientList: ---To add gradient colors---
// emptyColorGradient: ---Empty Color gradient---
)

:) Happy coding 😊
Got example from: Donut Pie Chart Example
// Donut chart example. This is a simple pie chart with a hole in the middle.
import 'package:charts_flutter/flutter.dart' as charts;
import 'package:flutter/material.dart';
class DonutPieChart extends StatelessWidget {
final List<charts.Series> seriesList;
final bool animate;
DonutPieChart(this.seriesList, {this.animate});
/// Creates a [PieChart] with sample data and no transition.
factory DonutPieChart.withSampleData() {
return new DonutPieChart(
_createSampleData(),
// Disable animations for image tests.
animate: false,
);
}
@override
Widget build(BuildContext context) {
return new charts.PieChart(seriesList,
animate: animate,
// Configure the width of the pie slices to 60px. The remaining space in
// the chart will be left as a hole in the center.
defaultRenderer: new charts.ArcRendererConfig(arcWidth: 60));
}
/// Create one series with sample hard coded data.
static List<charts.Series<LinearSales, int>> _createSampleData() {
final data = [
new LinearSales(0, 100),
new LinearSales(1, 75),
new LinearSales(2, 25),
new LinearSales(3, 5),
];
return [
new charts.Series<LinearSales, int>(
id: 'Sales',
domainFn: (LinearSales sales, _) => sales.year,
measureFn: (LinearSales sales, _) => sales.sales,
data: data,
)
];
}
}
/// Sample linear data type.
class LinearSales {
final int year;
final int sales;
LinearSales(this.year, this.sales);
}
