Build instructions

[Vendicated]

Please add build instructions! Trying to build this, I ran into multiple issues:

• couldn't find constructor "CookieManager" - Fixed by changing it to CookieManager.instance()
• APT: error: resource mipmap/ic_launcher not found: You specify this resource as icon but it does not actually exist in the resources folder - Fixed by removing the icon declaration
• Now build works but in app I run into NoSuchMethodError: Class XmlDocument has no instance method []. Tried calling []("post") (Edit: This actually only happens when searching for a buggy tag as mentioned in #164 so unrelated to this issue)

So clearly I'm missing something. Instructions would be appreciated!

Have you tried the newest version? After commenting out the ic_launcher line I was able to compile with flutter build apk --split-per-abi. I made a Dockerfile that I could PR as well.
