Solution 1 :
A way to solve this problem could be checking whether the File is empty or not.
So How to Check that would be:
val file = File("filepath/file.txt")
if (file.length == 0) {
// empty or doesn't exist
} else {
// exists and is not empty
}
Problem :
I have a set of data that i am storing into internal storage to be read for the next time. All i need to know if the file is completely written or not. because if not then for the next time read it will give a corrupt file. I need to avoid that.
I need something like a callback or a flag that tells data is completely written or not

You can if you know the exact/approximate amount of bytes that the file should be . You can replace the condition with
