(WIP) Fix for flutter 1.6 above.

Changed the api calls, this PR is work in progress as it depends upon stream_channel where I have sent another PR to address this issue.

Hi @lukaspili, it seems that you have abandoned this project. Are you ok to give someone full access to the repo so that they can maintain it? If you are comfortable with it then I would like to work on it as my organization heavily relies on this plugin and I want to add more to it.

Hey @awazgyawali I'm looking for a beacon lib but this one seems outdated, so I tried your update branch but I still having an issue when launching the example app, can you help me out ? 😁

It does work after many attempt 🤔 Dunno why

Hello @awazgyawali @nabinkh, I apologize for the very late response. My organization plans to restart maintenance of this plugin, starting in January. Are you still interested to join? I can give you a write access right now, so you can merge your work.

[awazgyawali]

Hi @lukaspili happy to see you back. We initially tried to maintain this project but as you were not available ATM we tweaked the project in such a way that now it only scans our beacons. So this PR shall not be merged else it will bring very false result.

@nabinkh and I are from the same team and we are also planning to build a package from scratch from around January. We shall continue working at that time, but for now, I am afraid I have to close this PR for the sake of sanity.

[lukaspili]

Sure. Sorry again for replying so late!
