Secret Message PoC Build Error

Development
1

@vilkris I’m trying to build this encrypted message PoC

However I get this error. I have installed the necessary dependency as outlined in the original post.

Dart SDK version: 3.4.0 (stable) (Mon May 6 07:59:58 2024 -0700) on "macos_arm64"

environment:
  sdk: '>=2.14.0 <3.0.0'

dependencies:
  dcli: ^1.7.1
  znn_sdk_dart:
    git:
      url: https://github.com/zenon-network/znn_sdk_dart.git
      ref: 367ddc7fbfefb6484d7553d9ac7e4532003a7008 # v0.0.4

Could this be a Dart version issue? Looks like the SDK is fixed.

This is because you’re running a newer dart version. Either use an old version or try dart pub upgrade.

OK - did that and then got this

mkdir -p build
dart compile exe cli_handler.dart -o build/znn-cli
init_znn.dart:83:9: Error: 'ArgParser' isn't a type.
  final ArgParser argParser = ArgParser();

Had to add import 'package:args/args.dart'; to init_znn.dart. Now I’m getting an argon error libargon2_ffi.dylib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e' or 'arm64'))

Looks like I’ll move to ‘x86_64’ and retry

OK - Im in. I’m going to send Zir Gay a message and see if he can get through all these hurdles. Check out the response below.

Can't fetch recipient public key because the recipient's account chain is empty.

I got it to work finally. Need to send to an account chain with more than 0 tokens in it. Let’s see if the recipient can decipher it.

@vilkris I sent you an encrypted message to test your PoC. I finally found a reason to use it. Curious if you can read this. LMK if anyone else wants to receive a message.
