Is it safe to use `Resources.getSystem()` to obtain the density for dp to px conversions? Could density “config change”?
```val Int.dp: Int
    get() = (this / Resources.getSystem().displayMetrics.density).toInt()

val Int.px: Int
    get() = (this * Resources.getSystem().displayMetrics.density).toInt()```


You are better off passing in resources or context.

that way you ensure this is called in the appropriate place

also I would do this:
TypedValue.applyDimension

Back to the old ways then. Just found out about `Resources.getSystem()` , it makes the extensions so clean…

imho, if you use `Resources.getSystem()`  inside a class the risk is that you can’t create unit test on it, because you are using a resource statically. This is my opinion in terms of testability.
