Pick colors from pixels of everything visible with flutter

pixel_color_picker

A widget that extracts colors from its childs.

This package lets you basically extract colors from everything in your screen.

pixel_color_picker

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  pixel_color_picker:

Import the package in your code:

import 'package:local_hero/local_hero.dart';

Wrap the target widget inside PixelColorPicker:

PixelColorPicker(
  child: Image.asset('image.png'),
  onChanged: (color) {
    setState(() {
      this.color = color;
    });
  }
);

And whenever the user taps the child, the onChanged event will give the color of the pixel on that position.

It's still under development, but you can already play with it.
