```dart
Map dataMap = {
"Flutter": 5,

"Xamarin": 2,
"Ionic": 2,
};
```
### - Simple Implementation
```dart
PieChart(dataMap: dataMap)
```
### - Full Implementation
```dart
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---
)
```
## ⭐ Features
### Control decimal places 'decimalPlaces'
```dart
chartValuesOptions: ChartValuesOptions(
decimalPlaces: 1,
),
```
### Change legend position with 'legendPosition'
### Change Chart shape to ring
```dart
chartType: ChartType.ring,
```
```dart
chartType: ChartType.ring,
showChartValuesOutside: true,
```
### Gradient Colors
Pie Chart supports gradient as colors. Just pass `gradientList` instead of `colorList` to add gradient to chart colors.
```dart
final gradientList = >[
[
Color.fromRGBO(223, 250, 92, 1),
Color.fromRGBO(129, 250, 112, 1),
],
[
Color.fromRGBO(129, 182, 205, 1),
Color.fromRGBO(91, 253, 199, 1),
],
[
Color.fromRGBO(175, 63, 62, 1.0),
Color.fromRGBO(254, 154, 92, 1),
]
];
// Pass gradient to PieChart
gradientList: gradientList,
emptyColorGradient: [
Color(0xff6c5ce7),
Colors.blue,
],
```
### Base Chart Color
Add a base pie-chart color via:
```dart
baseChartColor: Colors.grey
```
Full code:
```dart
class HomePage2 extends StatelessWidget {
HomePage2({Key? key}) : super(key: key);
final dataMap = {
"Flutter": 5,
};
final colorList = [
Colors.greenAccent,
];
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Pie Chart 1"),
),
body: Container(
padding: EdgeInsets.symmetric(horizontal: 16),
child: PieChart(
dataMap: dataMap,
chartType: ChartType.ring,
baseChartColor: Colors.grey[300]!,
colorList: colorList,
),
),
);
}
}
```
### Total Value
To show chart arcs based on your total value, add `totalValue` option.
```dart
class HomePage2 extends StatelessWidget {
HomePage2({Key? key}) : super(key: key);
final dataMap = {
"Flutter": 5,
};
final colorList = [
Colors.greenAccent,
];
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Pie Chart 1"),
),
body: Container(
padding: EdgeInsets.symmetric(horizontal: 16),
child: PieChart(
dataMap: dataMap,
chartType: ChartType.ring,
baseChartColor: Colors.grey[50]!.withOpacity(0.15),
colorList: colorList,
chartValuesOptions: ChartValuesOptions(
showChartValuesInPercentage: true,
),
totalValue: 20,
),
),
);
}
}
```
### Center Widget
Creates a new widget placed at pie chart center
```dart
centerWidget: Container(color: Colors.red, child: const Text("Center"))
```
