# flutter_luban
[](https://pub.dartlang.org/packages/flutter_luban)
An image compress package like [Luban](https://github.com/Curzibn/Luban) for Dart, based on [image](https://github.com/brendan-duncan/image).This library has no system platform constraints.
### Example
```dart
CompressObject compressObject = CompressObject(
imageFile:imageFile, //image
path:tempDir.path, //compress to path
quality: 85,//first compress quality, default 80
step: 9,//compress quality step, The bigger the fast, Smaller is more accurate, default 6
mode: CompressMode.LARGE2SMALL,//default AUTO
);
Luban.compressImage(compressObject).then((_path) {
setState(() {
print(_path);
});
});
```

# example
A new Flutter project.
## Getting Started
This project is a starting point for a Flutter application.
A few resources to get you started if this is your first Flutter project:
- [Lab: Write your first Flutter app](https://flutter.io/docs/get-started/codelab)
- [Cookbook: Useful Flutter samples](https://flutter.io/docs/cookbook)
For help getting started with Flutter, view our
[online documentation](https://flutter.io/docs), which offers tutorials,
samples, guidance on mobile development, and a full API reference.

# Launch Screen Assets
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43

# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# Read more about versioning at semver.org.

# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.io/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.io/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
