Use case

A SearchBar is usually used with a list of Widgets underneath that show the search results. When focusing the SearchBar in a ListView, the SearchBar scrolls into view so that it's at the bottom of the view, right above the keyboard. However, it would be useful if it scrolled a little more so that the search results would also be visible. This is something that could be achieved by implementing the scrollPadding property.

Proposal

Just like TextField does, SearchBar should have a scrollPadding property. This would enable control over how a SearchBar scrolls into view when the keyboard opens.
