Klutter plugin makes it possible to write a Flutter plugin for both Android and iOS using Kotlin only.

The Klutter Framework makes it possible to write a Flutter plugin for both Android and iOS using Kotlin Multiplatform. Instead of writing platform specific code twice in 2 languages (Swift + Kotlin), it can be written once in Kotlin and used as a Flutter plugin.

Important: Klutter is in alpha and not yet published to PUB.

Getting started

• Installation
• Use plugins
• Create plugins

Installation

Add the Klutter library to dev_dependencies in the pubspec.yaml:

dev_dependencies:
  klutter: ^0.1.0

Then run:

flutter pub get

Use plugins

Plugins build with the Klutter Framework work slightly different than regular plugins. First install the dev dependency. Next run the android command to setup Gradle:

flutter pub run klutter:android

This task will do 3 things for your Flutter project:

• Create a .klutter-plugins file in the root folder.
• Create a new Gradle file in the flutter/packages/flutter_tools/gradle.
• Update the android/settings.gradle file to apply the newly generated Gradle file.

The .klutter-plugins file will register all Klutter made plugins used in your project. The created Gradle file in the flutter_tools manages the plugins and enables them to be found by the Flutter project.

That's it! Now you can use plugins made with Klutter in your Flutter application by adding them to the dependencies in the pubspec.yaml. Register it in your project by running klutter:add. For example to add the library 'awesome_plugin' to your project run:

flutter pub run klutter:add awesome_plugin  

This will add the awesome_plugin to the .klutter-plugins file.

Create plugins

Start by creating a new Flutter plugin project. You can do this using the wizard in Android Studio or by running the following command, substituting 'org.example' with your organisation name and 'plugin_name' with your plugin name.

flutter create --org com.example --template=plugin --platforms=android,ios plugin_name

Then install the dev dependency. //TODO continue
