feat(ui): optional frosted liquid-glass on app-bar action chrome - #1249
Merged
Conversation
CircularIconButton gains an optional hazeState — when supplied it frosts whatever content scrolls beneath the bar (clip precedes hazeEffect so the blur is bounded to the circle); flat translucent fill when null. AppBarDefaults.UpNavigation/Close/Share and AppBarWithTitle thread the optional hazeState. Fully backward-compatible (default null = current look).

Summary
Adds an opt-in Haze "liquid glass" frost to the app-bar action chrome — reusable plumbing only, fully backward-compatible (default
null= today's look). The first consumer is the currency-info revamp (#1247, which stacks on this).CircularIconButtongains an optionalhazeState→ when supplied, the button frosts whatever content scrolls beneath the bar (clipprecedeshazeEffectso the blur is bounded to the circle); flat translucent fill whennull.AppBarDefaults.UpNavigation/Close/ShareandAppBarWithTitlethread the optionalhazeState.No behavior change on any existing screen (they pass no
hazeState).Test plan
