Source: https://pub.dev/packages/bodychart_heatmap/versions/1.0

Example of how to use the BodyHeatmap widget in a Flutter application. It visualizes body parts with intensity levels and allows customization of colors and tooltip behavior.

BodyHeatmap(
  selectedParts: {
    "chest": 1,
    "back": 3,
    "arm": 2,
    "leg": 3,
    "butt": 1,
    "shoulder": 0, 
    "neck": 1,
    "abs": 1,
  },
  baseColor: Colors.blueAccent,
  unselectedColor: const Color(0xFFCCCCCC),
  width: 350,
  showToolTip: true,
  toolTipTextStyle: const TextStyle(fontSize: 14, color: Colors.black),
  toolTipAlignment: MainAxisAlignment.end,
)
```

### Flutter App Entry Point with BodyChart and BodyHeatmap

Source: https://pub.dev/packages/bodychart_heatmap/example

This Dart code snippet demonstrates the main entry point for a Flutter application that utilizes the bodychart_heatmap package. It sets up a basic MaterialApp with a PageView to display both BodyChartExample and BodyHeatmapExample widgets, allowing users to swipe between them.

```dart
import 'package:example/views/bodychart.dart';
import 'package:example/views/bodyheatmap.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(home: HomePage());
  }
}

class HomePage extends StatelessWidget {
  const HomePage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.white,
      body: SafeArea(
        child: PageView(children: [BodyChartExample(), BodyHeatmapExample()]),
      ),
    );
  }
}

```

### Implement BodyHeatmap Widget in Flutter

Source: https://pub.dev/packages/bodychart_heatmap/versions/1.1

This Flutter code demonstrates the usage of the `BodyHeatmap` widget. It takes a map of body parts with intensity values and displays them on a human body chart with customizable colors, legend, and width. The intensity levels determine the color gradient.

```dart
import 'package:bodychart_heatmap/bodychart_heatmap.dart';

BodyHeatmap(
  selectedParts: {
    "chest": 5,
    "back": 4,
    "arm": 10,
    "leg": 5,
    "butt": 10,
    "shoulder": 0,
    "neck": 2,
    "abs": 8,
  },
  baseColor: Colors.blueAccent,
  unselectedColor: const Color(0xFFCCCCCC),
  width: 350,
  showLegend: true,
  legendTextStyle: const TextStyle(fontSize: 14, color: Colors.black),
  legendAlignment: MainAxisAlignment.end,
  intensityLevels: 3,
)

```

### Implement BodyChart Widget in Flutter

Source: https://pub.dev/packages/bodychart_heatmap/versions/1.1

This Flutter code demonstrates the usage of the `BodyChart` widget. It highlights selected body parts on a human body chart with a specified color. You can define the set of selected parts, colors, and the view type (front, back, or both).

```dart
import 'package:bodychart_heatmap/bodychart_heatmap.dart';

BodyChart(
  selectedParts: {"chest", "arm", "abs","back","butt"},
  selectedColor: Colors.green,
  unselectedColor: Colors.grey.shade300,
  viewType: BodyViewType.both,
  width: 250,
)

```

### Deprecated `withOpacity` Usage in bodyheatmap.dart

Source: https://pub.dev/packages/bodychart_heatmap/score

This snippet highlights a deprecated usage of `withOpacity` in the `lib/src/bodyheatmap.dart` file. The warning suggests using `.withValues()` instead to prevent precision loss. This is a common issue in older Flutter codebases that need updating.

```dart
    color: baseColor.withOpacity(opacity),
```

--------------------------------

### Deprecated `alpha` Usage in util.dart

Source: https://pub.dev/packages/bodychart_heatmap/score

This snippet points out a deprecated usage of `alpha` in the `lib/src/utils/util.dart` file. The recommended approach is to use `(*.a * 255.0).round().clamp(0, 255)`. This indicates a need to update color manipulation logic in the utility functions.

```dart
      buffer.write(alpha.toRadixString(16).padLeft(2, '0'));
```
