As always when there is a clickbaity title that you think cannot be true it just lacks any nuance. Toasts are for displaying updates on things that happen OFF SCREEN, eg when doing something that takes a while and navigating to another screen. In addition toasts require a home for context to work propperly. This can either be a stack of toasts for very simple applications or a notification sidebar that can be accessed from a bell icon or similar. Toasts need to be shown close to this entry point to their home, not on an opposite position of the screen. The 2 most common mistakes are: a) show toasts for things that happen on screen instead of showing feedback in the actual action UI (its fine to keep them in addition for consistnecy) b) not have a home where a user can see what happened combined with autohiding toasts after a few seconds. (i cannot count how often i saw some dangerous looking error toast but could not read it in time, leaving me with a bad feeling especially for important things like admin UIs)
