Image Filter Pro #

Hi! This is my first package published to help you out! Image Filter Pro is a Flutter package that provides a convenient way to apply color filters to images with preset filter options. The package is written purely in Dart, so no additional setup for specific platforms is required.

Features #

• Apply various preset color filters to images.
• Easily integrate customizable filter UI into your Flutter app.
• Inspired by popular filter presets found in other image editing apps.

Installation #

Add the following dependency to your pubspec.yaml file:

dependencies: image_filter_pro: ^0.1.0

Usage #

Import the package:

import 'package:flutter/material.dart';
import 'package:image_filter_pro/image_filter_pro.dart';

Use the ImageFilterWidget in your widget tree:

class MyImageFilterApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Image Filter App'),
        ),
        body: Center(
          child: ImageFilterWidget(
            image: File('path_to_your_image.jpg'),
            filters: NamedColorFilter.defaultFilters(),
            cancelIcon: Icons.cancel,
            applyIcon: Icons.check,
            backgroundColor: Colors.black,
            sliderColor: Colors.blue,
            sliderLabelStyle: TextStyle(color: Colors.white),
            bottomButtonsTextStyle: TextStyle(color: Colors.white),
            filtersLabelTextStyle: TextStyle(color: Colors.white),
            applyingTextStyle: TextStyle(color: Colors.white),
          ),
        ),
      ),
    );
  }
}

void main() {
  runApp(MyImageFilterApp());
}

You can also provide your own set of presets like this:

ImageFilterWidget(
              filters: [
		                  // Always add the "default" one
						  NamedColorFilter(  
						    colorFilterMatrix: [],  
						    name: "None",  
						  ),  
						  NamedColorFilter(  
						    colorFilterMatrix: [  
						      0.8, 0.1, 0.1, 0, 20,  
						      0.1, 0.8, 0.1, 0, 20,  
						      0.1, 0.1, 0.8, 0, 20,  
						      0, 0, 0, 1, 0,  
						    ],  
						    name: "Vintage",  
						  ),  
						  NamedColorFilter(  
						    colorFilterMatrix: [  
						      1.2, 0.1, 0.1, 0, 10,  
						      0.1, 1, 0.1, 0, 10,  
						      0.1, 0.1, 1, 0, 10,  
						      0, 0, 0, 1, 0,  
						    ],  
						    name: 'Mood',  
						  ),  
					]
        )

Or if you want to extend:

ImageFilterWidget(
              filters:  NamedColorFilter.defaultFilters().toList().addAll([ 
						  NamedColorFilter(  
						    colorFilterMatrix: [  
						      0.8, 0.1, 0.1, 0, 20,  
						      0.1, 0.8, 0.1, 0, 20,  
						      0.1, 0.1, 0.8, 0, 20,  
						      0, 0, 0, 1, 0,  
						    ],  
						    name: "Vintage",  
						  ),  
						  NamedColorFilter(  
						    colorFilterMatrix: [  
						      1.2, 0.1, 0.1, 0, 10,  
						      0.1, 1, 0.1, 0, 10,  
						      0.1, 0.1, 1, 0, 10,  
						      0, 0, 0, 1, 0,  
						    ],  
						    name: 'Mood',  
						  ),  
					]
        )
