SOURCE CODE
===========

Plugin Implementation
---------------------





Init Project
------------

Generate Project: 
::

	# generate flutter plugin project
	$ flutter create --org io.malloc.ccc --template=plugin  ccipherchain

	# generate with kotlin and swift support
	$ flutter create --org io.malloc.ccc --template=plugin -i swift -a kotline  ccipherchain 



	DART plugin code is in:  ccc_fplugin/lib/ccc_fplugin.dart
  JAVA plugin code is in:  android/
  iOS  plugin code is in:  ios/

	EXAMPLE code is in:  ccc_fplugin/example/lib/main.dart
	  $ cd ccc_fplugin/example
	  $ flutter run



Open Android Java Project to edit: 
  * **OPEN: ./example/android/build.gradle  file  in Android Studio**
  * to edit platform code in an IDE see https://flutter.io/developing-packages/#edit-plugin-package.

ISSUES
======


edit ./android && ./example/android
-----------------------------------

**OPEN: ./example/android/build.gradle  file  in Android Studio**

the gradle file there also includes the flutter plugin project, which 
will also cascade to include the android project, etc...VERY convoluted!!
BASTARDS!!
