Setup

Android

ProGuard

Add this lines to android/app/proguard-rules.pro for proguard support

-keep class go.** { *; }
-keep class rsa.** { *; }

iOS

no additional setup required

Web

add to you pubspec.yaml

  assets:
    - packages/fast_rsa/web/assets/wasm_exec.js
    - packages/fast_rsa/web/assets/rsa.wasm

ref: https://github.com/jerson/flutter-rsa/blob/master/example/pubspec.yaml

and in you web/index.html

<script src="assets/packages/fast_rsa/web/assets/wasm_exec.js" type="application/javascript"></script>

ref: https://github.com/jerson/flutter-rsa/blob/master/example/web/index.html

Linux

add to you linux/app_configuration.mk

EXTRA_LDFLAGS=-lrsa

ref: https://github.com/jerson/flutter-rsa/blob/master/example/linux/app_configuration.mk

MacOS

no additional setup required

Hover

just update your plugins

hover plugins get

Example

Inside example folder

cd example && flutter run

Native Code

the native library is made in Golang and build with gomobile for faster performance
