How to use this library? about libsignal_protocol_dart

[boyan01]

This is most likely related to WINRT, I did not google yet how I can install it. Sorry for my laziness.

The same as MixinNetwork/flutter-plugins#185 Upgrade visual studio version to latest would solve this error.

Here we have a better example to show how to use this lib that you can try.
#62

And could you please share compilation error message, maybe we can help with this.

I got this compile error here (the encoding errors are already in my console):

Nuget.exe not found, trying to download or use cached version.

I just noticed that the repo of the PR 62 was deleted. How can I checkout that PR? Was there not some kind of hidden branch?

EDIT Got it with:

git clone [email protected]:MixinNetwork/libsignal_protocol_dart.git
git fetch origin pull/62/head:example_app
git switch example_app

[Tougee]

A new branch example has been added.

@boyan01 can you help with flutter-app compilation error?
