Hi all!
I'm reading a huge file/object from a remote source in bunches... send fragments of the file thru a Flow and wanna process complete lines one by one.
I got below implementation... but I was wondering if there is a way to get rid of the var and get a more functional solution.
Thanks in advance.
```fun main() = runBlocking {
    var lastline = ""
    readHugeFile().collect { value -&gt;
        val lines = (lastline+value).lines()
        lines.dropLast(1).forEach {
            println(it)
        }
        lastline = lines.last()
    }
    println(lastline)
}

fun readHugeFile(): Flow&lt;String&gt; = flowOf(
    """line 1
        |line 2
        |li""".trimMargin(),
    """ne 3
        |line 4
        |lin""".trimMargin(),
    """e 5
        |line 6
        """.trimMargin()
)```

`.fold` instead of `.collect` is probably what you're looking for
