remove bracket hell for using flow

collectIt.kt

fun <T> StateFlow<T>.collectIt(lifecycleOwner: LifecycleOwner, function: (T) -> Unit) {
    // Create a new coroutine in the lifecycleScope
    lifecycleOwner.lifecycleScope.launch {
        // repeatOnLifecycle launches the block in a new coroutine every time the
        // lifecycle is in the STARTED state (or above) and cancels it when it's STOPPED.
        lifecycleOwner.repeatOnLifecycle(Lifecycle.State.STARTED){
            collect {
                // Trigger the flow and start listening for values.
                // This happens when lifecycle is STARTED and stops
                // collecting when the lifecycle is STOPPED
                function.invoke(it)
            }
        }
    }
}
