I want to use Lambda expression but I am getting such error. Can anyone help ?

[Kirill Rozhenkov]

this is what I do in my projects:

fun <D : Any, T : LiveData<D>> T.observeWith(owner: LifecycleOwner, receiver: (D) -> Unit) {
    observe(owner, Observer<D> {
        if (it != null) {
            receiver(it)
        }
    })
}

and then you can call this function in your code like this: loginViewModel.progress().observeWith(this, this::onProgress)
