SDK: DART SDK

[romanovichim]

Hi, we have made a library for TON Connect:

• github
• pub.dev
• Example of usage

We are writing this,if suddenly you want to add links to the Readme.

P.S Dart allows you to create cross-platform applications on Flutter

Hi, good job 👍 Sure, I can add a link to the library in this repo. Would you consider moving dart-sdk repo to the ton-connect github organisation?
