StreamBottomAppBarStyle class

Visual styling properties for a StreamBottomAppBar.

Defines the appearance of the bottom app bar — background colour, padding, inter-slot spacing, title and subtitle text styles, and per-slot button style propagation.

Exposed separately from StreamBottomAppBarThemeData so other theme data classes can embed a bottom-app-bar style via a typed field.

{@tool snippet}

Compose a style and hand it to a bottom app bar theme:

StreamBottomAppBarStyle(
  backgroundColor: Color(0xFFFFFFFF),
  padding: EdgeInsets.symmetric(horizontal: 16, vertical: 12),
  spacing: 8,
)

{@end-tool}

• StreamBottomAppBarThemeData, which wraps this style for theming.
• StreamBottomAppBar, which uses this styling.
