• Trim the package description to 168 characters. pub.flutter-io.cn caps it at 180 and was withholding all 10 pubspec.yaml points for the overrun.

• Shrink the published archive from 27 MB to a few KB. 0.2.0 accidentally shipped the example's generated Android/iOS/web scaffolding; it is now excluded. No code changes — upgrade from 0.2.0 purely for the size.

• Any widget can go in the bar. Added largeTitle and compactTitle, which take arbitrary widgets — a heading with a subtitle, an avatar row, a search field, tabs — instead of only a string.
• title is now optional. Pass it for the plain-text case, or supply both custom widgets and omit it. Supplying title alongside one custom widget fills in the other, so you can override just one side.
• Theme-aware by default. scrimColor and both title styles now fall back to the ambient Theme instead of hardcoded white-on-dark-green, so the bar is readable in a stock light or dark app without passing any colors.
• Documented every public API element.

Breaking #

• scrimColor is now Color? and defaults to ThemeData.scaffoldBackgroundColor. If you relied on the old 0xFF06140A default, pass it explicitly: scrimColor: const Color(0xFF06140A).
• Default title colors follow ColorScheme.onSurface rather than always being white. Pass largeTitleStyle / compactTitleStyle to restore the old look.

• Add changelog entries for released versions (pub.flutter-io.cn convention fix).

• Add screenshots to the README.
• Add optional external ScrollController via the controller parameter.

• Initial release.
• GhostAppBarScaffold: invisible app bar with gradient scrim, large title that fades out on scroll, and compact title that fades into the bar.
• GhostAppBarScaffold.children convenience constructor for box widgets.
