:kotlin:otlinize! #inlinereified

inline fun <reified T : ViewModel> FragmentActivity.getViewModel(key: String? = null): T {
    val provider = ViewModelProviders.of(this)
    return if (key != null) {
        provider.get(key, T::class.java)
    } else {
        provider.get(T::class.java)
    }
}

usage:

userViewModel = getViewModel()

instead of:

userViewModel = ViewModelProviders.of(this).get(UserViewModel::class.java)

mg6maciej:

return ViewModelProviders.of(this)
.run {key?.let {get(it, T::class.java)} ?: get(T::class.java)}

This does not look

fun

. I'm a stupid person and like my code not to be smarter than me. ;)

Nice one😆
