What is the actual duration of a Snackbar with LENGTH_LONG

Since I've migrated my Android Project to AndroidX i am receiving the following lint error:

Error: Must be one of: Snackbar.LENGTH_INDEFINITE, Snackbar.LENGTH_SHORT, Snackbar.LENGTH_LONG [WrongConstant]
        Snackbar snackbar = Snackbar.make(rootView, message, sticky ? Snackbar.LENGTH_INDEFINITE : 4500

So instead of defining a custom duration (4500ms), I am now using Snackbar.LENGTH_LONG. Since i am implementing some time-based operation that depends on how long the snackbar is visible, I need to know the actual duration of Snackbar.LENGTH_LONG in milliseconds. How do I find out that value?

The docs are not really helpful here:

Show the Snackbar for a short period of time.

androidx android-snackbar lint android

After some fishing in the source code you will find these constants in the SnackbarManager:

private static final int SHORT_DURATION_MS = 1500;
private static final int LONG_DURATION_MS = 2750;

So to answer your question the actual duration for the long length is 2750 milliseconds.

Class com.google.android.material.snackbar.SnackbarManager:

As stated by jbarat, but here's it in the source code as asked by a user. Could not reply in the thread, and so posting it as an answer. 2.75 Seconds
