LAYOUT

AppBar

AppBar provides top-level navigation through explicit top, start, center, end, and bottom regions.

MENTAL MODEL

Place the bar in a Scaffold

Scaffold owns shell placement. AppBar owns the horizontal content regions and their visual surface. boxed:true keeps that surface full width while centering its inner content at 96rem on web or 1536 logical units on Android and iOS.

AppBar stays visually flat on web, Android, and iOS unless you declare border, bordered:true, or floating:true. A sticky floating AppBar placed directly in Scaffold appBar overlays the web and desktop main body so page content remains visible beneath its surface. Sticky and fixed placement does not add an implicit divider, elevation, or shadow.

LIVE EXAMPLES

AppBar inside its real shell

Each preview is a complete routed page with one Scaffold, so scrolling and shell spacing remain observable.

Fixed and boxed

Floating, docked on scroll

Scroll beyond 100 logical units to animate the fixed floating surface into the viewport top edge on web, Android, and iOS. Native side controls remain on one line while the surface changes width, radius, and border.

Full-width regions and scroll reveal

Scroll down to hide the AppBar, then scroll upward to reveal it again.

REGIONS

A full-width frame around the main row

top and bottom span the AppBar. start and end size to their content, while center takes the flexible space between them. Each region can contain ordinary view nodes.

Use sticky or fixed AppBars inside Scaffold appBar. Scaffold measures fixed bars automatically; outside Scaffold, a fixed AppBar overlays normal web content.
