## Features

- Generate random colors with fine-tuned control

- Specify color types, luminosity, and output formats

- Direct integration with Flutter's `Color` class

- Highly customizable with easy-to-use API

- Consistent results across platforms

## Installation

Add this to your package's `pubspec.yaml` file:

```yaml

dependencies:

  flutter_randomcolor: ^1.0.16

```

Then run:

```bash

$ flutter pub get

```

## Quick Start

```dart

import 'package:flutter_randomcolor/flutter_randomcolor.dart';

// Generate a random color

var color = RandomColor.getColor(Options());

// Generate a Flutter Color object

Color flutterColor = RandomColor.getColorObject(Options());

```

## Usage Guide

### Basic Usage

Generate a random color with default options:

```dart

var color = RandomColor.getColor(Options());

```

### Flutter Integration

Get a `Color` object for direct use in Flutter widgets:

```dart

Color widgetColor = RandomColor.getColorObject(Options(

  colorType: ColorType.blue,

  luminosity: Luminosity.light,

));

// Use in a widget

Container(

  color: widgetColor,

  child: Text('Colored Container'),

)

```

### Advanced Options

Fine-tune your color generation:

```dart

var customColor = RandomColor.getColor(Options(

  colorType: [ColorType.red, ColorType.blue],

  luminosity: Luminosity.dark,

  format: Format.rgba,

  alpha: 0.8,

));

```

## API Reference

### `RandomColor.getColor(Options options)`

Returns a color based on the specified options.

### `RandomColor.getColorObject(Options options)`

Returns a Flutter `Color` object based on the specified options.

### `Options` class

- `colorType`: `ColorType` or `List`

- `luminosity`: `Luminosity`

- `format`: `Format`

- `alpha`: `double` (0.0 to 1.0)

- `count`: `int`

#### ColorType

`random`, `monochrome`, `red`, `orange`, `yellow`, `green`, `blue`, `purple`, `pink`

#### Luminosity

`random`, `dark`, `light`, `bright`

#### Format

`rgba`, `rgb`, `rgbArray`, `hsla`, `hex`, `hsl`, `hsva`, `hsvArray`, `hslArray`

## Examples

```dart

// Bright green color in hex format

var brightGreen = RandomColor.getColor(Options(

  colorType: ColorType.green,

  luminosity: Luminosity.bright,

  format: Format.hex

));

// Array of 5 pastel colors

var pastelColors = RandomColor.getColor(Options(

  luminosity: Luminosity.light,

  count: 5

));

// Dark red or blue with 50% opacity

var transparentDark = RandomColor.getColor(Options(

  colorType: [ColorType.red, ColorType.blue],

  luminosity: Luminosity.dark,

  format: Format.rgba,

  alpha: 0.5

));

```
