Horizontal button order

On Windows, when presenting a row of buttons,
the confirmation button is placed at the start of
the row (left side). On all other platforms,
it’s the opposite. The confirmation button is
placed at the end of the row (right side).

This can be easily handled in Flutter using the
TextDirection property on Row:

Menu bar

Another common pattern on desktop apps is the menu bar.
On Windows and Linux, this menu lives as part of the Chrome title bar,
whereas on macOS, it’s located along the top of the primary screen.

Currently, you can specify custom menu bar entries using
a prototype plugin, but it’s expected that this functionality will
eventually be integrated into the main SDK.
