🎉 Add Web support

[czepiec]

This PR adds support for Web platform as discussed in #16. The authentication service will open in a new browser window. To capture callback URL you need to create an HTML file with JavaScript postMessage() method which sends URL to the application. It is explained with an example in README.md.

Any status update on this getting merged? I've been using it in my production app for awhile and it works perfectly.

[Silfalion]

Would really like to see it added too.

@LinusU in the last weeks I have made some improvements to the PR, but I do not expect any other future changes. I think it's quality code, was reviewed and it's used in several production environments. If there's anything that needs to be discussed, I'm here.

@czepiec sorry for the ping. I was planning to collect all pull requests into one repo but I have trouble running your PR.

The first problem I encounter is that the websocket cant bind because of flutter web.

I was able to overcome that by creating a separate project and testing without a server but using localhost my path(localhost:port/auth.html) can't be reached they say. Did you encounter this issue?

[Silfalion]

Hey, the appwrite org agreed to open a repo just for flutter_web_auth in the meantime LinusU is back, pushed a pull request with the changes here:

appwrite#1

[Silfalion]

Thank you for merging it!

[LinusU]

So sorry for the long delay on this! My goal is to transition this package over to some community that can maintain it 😅

This is now published as 🚢 0.3.2 / 2021-12-11

[Silfalion]

No worries at all! When life gets busy there is no fighting it. I’m not thaaat familiar with the code right now but I’m willing to help if you’re ok with that.

[czepiec]

Thanks @LinusU.

For everyone who uses my fork, I keep it active until the end of 01/2022, then I will have to delete it. Change your dependency back to the upstream, I recommend version 0.4.0 with Android V2 embedding 🙂.

@Silfalion I admit I don't understand to

The first problem I encounter is that the websocket cant bind because of flutter web.

In production, this is usually solved by starting the websocket server on another port and then pass a path to it on the web server (e.g. NGINX).
