Issue:
[Snackbar] Update the implementation to match the new specification
The specification has changed many detail aspects of the snackbar. For instance, you will find different padding values, a different style on mobile, a different default animation, etc. You can find the full specification following this link: https://material.io/design/components/snackbars.html.
