Description

As we know, currently any kind of kotlin code that has been made into java from dex (for example with fernflower by extracting dex and using d2j-dex2jar) looks... java-ish. Kotlin has functions which aren't possible in normal java in normal circumstances, like proper null-handling on compiler level, coroutines, automatic simple getters and setters, etc... Vineflower is a fork of Fernflower, first ever decompiler which supports kotlin, as well as it's main purpose is to be as accurate as possible while retaining readability, for example with actually supporting kotlin, if source file is actually in kotlin. It would be greatly appreciated if along other decompilers Vineflower would also be there to provide another look at the code.
