Eyedropper

Select a color from your Flutter mobile or desktop screen.

To use the eyedropper you need to wrap the app in the EyeDrop widget.

@override
  Widget build(BuildContext context) {
    return EyeDrop(
      child: Builder(
        builder: (context) => Scaffold(
          backgroundColor: backgroundColor,
          body: Container(
            child: ColorButton(
              key: Key('c1'),
              color: color1,
              config: ColorPickerConfig(enableEyePicker = true),
              size: 32,
              elevation: 5,
              boxShape: BoxShape.rectangle, // default : circle
              swatches: swatches,
              onColorChanged: (value) => setState(() => color1 = value),
            ),
          ),
        ),
