Snackbars provide brief temporary non-interrupting notifications at the bottom of the screen.
Snackbars provide an update on a process that has or will be performed. Snackbars deliver low priority information—while Banners deliver medium priority and Dialogs deliver high priority information. Snackbars appear centered at the bottom of the screen and disappear without user interaction. On wider screens they are left-aligned. Snackbars appear on-screen between 5-10 seconds before dismissing themselves, so keep text short.
Snackbars can have one action. This action should not be “Close ” or “Dismiss” since snackbars disappear automatically. Actions such as “Undo” or “Retry” are acceptable. Snackbars can wrap up to two lines of text on smaller screens.
