Installation

First, add image_native_resizer as a dependency in your pubspec.yaml file.

Quickstart

import 'package:image_native_resizer/image_native_resizer.dart';

final localImagePath = /*** ***/;
final resizedPath = await ImageNativeResizer.resize(
    imagePath: localImagePath,
    maxWidth: 512,
    maxHeight: 512,
    quality: 50,
);

Inspired by `image_picker`

This plugin is almost identitical to the official image_picker plugin. Serveral internal files from the plugin are used to implement the resizing logic, this plugin is just exposing them through a platform channel.
