OnImageMatrixWidget class

This widget will make everything more easy to edit basics information of a image using native matrix you'll be able to control the brightness, exposure, contrast, saturation, etc.. of a image(or a widget), apply filter and convert this widget into a image(bytes).

This package isn't focused on professional image(widget) editting.

All edit use native code(matrix) and widget(ColorFiltered and ImageFiltered).

Examples:

Editting only one matrix:

body: OnImageMatrixWidget(
  colorFilter: OnImageMatrix.brightness(3.0),
  child: Image.network(
    'https://source.unsplash.com/j0QOYiYwIYE/1600x900',
  ),
),

Applying a filter:

body: OnImageMatrixWidget(
  colorFilter: OnImageFilters.gray1,
  child: Image.network(
    'https://source.unsplash.com/j0QOYiYwIYE/1600x900',
  ),
),

Editting mutiples matrices:

body: OnImageMatrixWidget(
  colorFilter: OnImageMatrix.matrix(
    brightnessAndContrast: 5.0,
    exposure: 1.0,
    saturation: 2.0,
    visibility: 1.0,
  ),
  child: Image.network(
    'https://source.unsplash.com/j0QOYiYwIYE/1600x900',
  ),
),

Using the OnImageMatrixWidget you won't be able to 'get' this widget and convert into a image. To achieve this you will use the OnImageMatrixWidget.builder.

Example:

body: OnImageMatrixWidget.builder(
  controller: _controller, // required
  imageKey: _globalKey, // required
  colorFilter: OnImageMatrix.matrix(
    brightnessAndContrast: 0.0,
    exposure: 0.0,
    saturation: 1.0,
    visibility: 1.0,
  ),
  child: Image.network(
    'https://source.unsplash.com/j0QOYiYwIYE/1600x900',
  ),
),

To save this widget into a image(bytes) use the controller

onTap: () {
  controller.save();
}

To get the bytes:

onTap: () {
  Uint8List imageBytes = controller.imageBytes;
}
