A sample app for Flutter cropping images package named crop_your_image.

https://pub.dev/packages/crop_your_image

I'm always waiting for your PRs adding YOUR designed page for cropping images: currently no fixed rules or templates as long as using crop_your_image package.

How to Add Pages

Preparation

To preparing for adding pages, you can simply clone this repository and run with whatever platform you want.

List of the Pages

There is lib/main.dart which contaning ListView of pages.

Pages data is preserved in List<Widget> at the very top of _MyHomePageState like below.

static const pages = const [
  FullScreenCrop(),
  ColorefulScreenCrop(),
  ConfigurableCrop(),
];

When you add your own page, you can add one to this list and the link to that page will appear automatically.

ImageDataNotifier

As ImageDataNotifier is placed at the top of Widget tree of this app, you can refer downloaded image data at whatever widgets or pages you want.

ImageDataNotifier simply downloads images when the app is launched and exposes the list of image data as type of Uint8List, named loadData.

Note that empty loadData means "still loading", so you can instantly control the UI with it.

For example:

@override
Widget build(BuildContext context) {
  final imageData = context.watch<ImageDataNotifier>();
  return Visibility(
    visible: imageData.loadData.isNotEmpty,
    child: imageData.loadData.isNotEmpty
      ? Crop(
        controller: _controller,
        image: imageData.loadData[0],
        onCropped: (cropped) {
            // any action using cropped data
        },
      )
      : const SizedBox.shrink(),
    replacement: const Center(child: CircularProgressIndicator()),
  );
)

How to Make Pull Requests

There is no rule for PRs. Feel free to add your own pages and make PRs to this repository. Once your PR is merged, I would like to add its screenshot and the link to author at "Gallery" section of this README.md. Thank you.
