Hi Belal, I have been following your series since four years. Mainly the Kotlin Concepts you posted were very helpful to me. I am very thankful. Are these Kotlin concepts enough to develop Android applications? Or are there any more advanced concepts like multithreading and collections? If so, will you post those concepts?
I have covered everything that is required for building android apps. I will also start app dev from scratch course soon. For concurrency we will use coroutines and there is a separate playlist available to learn this in my channel.
