Cover image

croppy

A fully customizable image cropper for Flutter, with built-in Material and Cupertino croppers.

Check out the example at https://kekland.github.io/croppy.

Supported platforms:

Android
iOS
Windows
Linux (untested, but should work)
macOS
Web (uses Dart's Cassowary instead of FFI because there's no FFI support in web)

NOTE: see https://github.com/kekland/croppy/issues/38. Currently I'm very busy with other projects so support might be limited.

Features

Material image cropper (similar to Google Photos)
iOS Photos app-like image cropper
Support for any linear transformations on the image: scaling, rotating, skewing, flipping, etc
Completely customizable (will create documentation with later releases)
Fixed aspect ratios
Custom cropping shapes
Kickass animations
Localization

In progress:

Image editing module (?) (brightness, contrast, etc)

Getting started

Install croppy from pub:

dependencies:
  croppy: <latest_version>

Enjoy using it :)

Usage

Currently croppy supports a Material (Google Photos-like) and a Cupertino (iOS Photos-like) image croppers:

final result = await showMaterialImageCropper(
  context,
  imageProvider: const NetworkImage('MY_IMAGE_URL'), // Or any other image provider
);

final result = await showCupertinoImageCropper(
  context,
  imageProvider: const NetworkImage('MY_IMAGE_URL'), // Or any other image provider
);

Voilà! You can now start cropping images.

For a complete runnable example, see ./example. For the full in-depth documentation, including customization, see the documentation.

Localization

croppy currently supports the following languages:

English
Kazakh
Russian
Arabic (thanks @Milad-Akarie)
Vietnamese (thanks @ptanhVNU)
Portuguese (thanks @JCKodel)
Spanish (thanks @Thesergiolg99)
Chinese (thanks @yohom and @zhushenwudi)

If there's a language that you would like to add, please see the localization guide.

It's recommended to insert the CroppyLocalizations.delegate in your MaterialApp or CupertinoApp:

MaterialApp(
  localizationsDelegates: [
    CroppyLocalizations.delegate, // <- This here
    GlobalMaterialLocalizations.delegate,
    GlobalWidgetsLocalizations.delegate,
    GlobalCupertinoLocalizations.delegate,
  ],
  ...
)
