Summary

Implements the order-book design handoff: 4b (order card and screen) and 4d (circular create-order button and its open state). 4a and 4c were discarded in the handoff and are not implemented.

Card (4b)

  • Header: currency chip, at most one highlight chip (BEST PREMIUM / MOST REPUTABLE), relative time flush right.
  • Amount: grouped per locale (832 – 5.000) and never truncated. Caption Market price, or Fixed amount · for 4.000 sats when the order carries a fixed sats amount (NIP-69 amt > 0, already parsed in order_events.rs).
  • Premium: plain coloured text, no pill, one decimal with sign (+5,0%, 0,0%, -1,5%).
  • Payment methods on their own line, joined with , , 2 lines max with ellipsis.
  • Reputation strip: star (grey when unrated), rating or New, | N trades | N days, no trades for a new maker.
  • The best-premium card gets the highlight border. Nothing in the card has a fixed height.

Behaviour decisions

  • Premium colour and "best premium" follow the taker's side. On Buy BTC (taking sell orders) a low premium is good; on Sell BTC (taking buy orders) a high one is. Green ≤ 0 points against the taker, amber ≤ 3, orange > 3. "Best premium" is awarded only when that order beats at least one other, so a lone order or a flat list gets no chip.
  • "Just published" chip removed: the design defines only two highlight chips.
  • New sort picker: Newest (default), Best premium (per the rule above), Best reputation (rating, then trades). Every criterion falls back to newest first.

Screen

  • App bar per the mock (hamburger, mascot at 26 dp, bell with a ringed dot).
  • Pill Buy/Sell segmented control; the list cross-fades in 150 ms on switch.
  • Filter row: Filter chip, N orders, and the current sort, which opens the picker.
  • Empty state: faded mascot, title, and one line. Clear filters appears only when filters hide every order.
  • Skeleton cards with the card's radius and height (shimmer, no spinner).

Create-order button (4d)

  • 56-dp circle; open state rendered through an OverlayPortal, so the scrim covers the whole screen, bottom bar included (the Scaffold only gives the FAB its own slot).
  • Equal full-width Buy/Sell buttons (52 tall, radius 16) above the button; the button becomes a grey ✕ in place. Scrim fades in 150 ms, buttons rise 8 dp and fade in 180 ms, ✕ rotates over 200 ms.
  • The scrim, the ✕ and system back close it.

Shared pieces

  • Bottom bar restyled (68 tall, short labels Book / Trades / Chat). It is shared, so Trades and Chat get it too.
  • NotificationBell gains optional styling; screens that pass nothing keep the old look.
  • OrderBookPalette moves to lib/core/order_book_palette.dart (re-exported from app_theme.dart) with the handoff's tokens.

Fonts

Outfit (UI, now the theme's default family, app-wide) and Manrope (figures) are bundled as static TTFs, so there is no runtime fetch from Google. Their OFL licences ship as assets and are registered with LicenseRegistry at startup.

Deviations from the handoff

  • AA contrast: textFaint #6B7589#808A9E (was 3.5:1 on the card). The handoff is dark-only, so the light palette is a derived legibility mapping; every text role in both themes is locked by order_book_palette_contrast_test.dart.
  • Icons: the app's Material icons at the specified sizes; stroke widths are not configurable.
  • Relative time: keeps the existing capitalised strings (Hace 36m) because notifications share them; the mock shows hace 36m.
  • Tablet/desktop grid: still uses a fixed tile aspect ratio (unchanged from before).

Goldens

order_list_item_{dark,light}.png change with the card. Update goldens has been dispatched on this branch; its commit makes the Flutter job green. If #422 (Flutter 3.41.9) merges first, re-run it after rebasing.

Test plan

  • New: order_sort_test, order_reasons_test, order_list_item_test (premium colours per side, rounding, amount grouping, fixed sats vs market, payment lines, reputation, highlight border, 320 dp with 2× text), order_list_empty_test, order_sort_sheet_test, add_order_button_test (full-screen scrim over the bottom bar, equal buttons, dismiss, navigation), bottom_nav_bar_test.
  • order_book_palette_contrast_test rewritten: every text role ≥ 4.5:1 in dark and light.
  • flutter analyze: no new issues.
  • flutter test: 437 passed; only the two card goldens fail, pending regeneration.
  • Visual check: the screen rendered at 360×760 with the bundled fonts, dark and light, list and open states, compared against 4b/4d.
  • CI green after the goldens commit.
  • Manual check on Android: FAB open/close animation, back closes it, sort picker, text scale 2×.
  • Web smoke test: fonts and mascot load.

Summary by CodeRabbit

  • New Features
    • Redesigned order book with Buy/Sell controls, responsive masonry layout, improved order cards, and clearer premium and reputation indicators.
    • Added sorting options for newest, best premium, and best reputation.
    • Added updated bottom navigation and full-screen create-order menu with improved accessibility.
    • Added Outfit and Manrope typography with bundled license information.
  • Bug Fixes
    • Improved order routing, filter empty states, loading placeholders, and light/dark theme contrast.
  • Localization
    • Updated order-book, navigation, filtering, and empty-state text across supported languages.

Order-book handoff, variants 4b (order card) and 4d (create-order button).

- Card: currency chip, one highlight chip per list, relative time; the
  amount grouped per locale and never truncated, captioned "Market price"
  or "Fixed amount · for N sats" from the order's `amt`; the premium as
  plain coloured text read from the taker's side (green in their favour,
  amber up to 3 points against, orange beyond); payment methods on their
  own line, two lines max; reputation strip with "New / no trades".
- Best premium now means best for the taker on each tab (lowest when buying
  BTC, highest when selling) and is awarded only when it beats another
  order; the best-premium card gets the highlight border. The "just
  published" chip is gone: the design defines only two.
- New sort picker (newest, best premium, best reputation), applied in
  filteredOrdersProvider with newest as the tie-breaker.
- Screen: pill Buy/Sell tabs with a 150 ms list cross-fade, filter row with
  order count and sort caption, new empty state (clear filters when filters
  hide everything) and skeleton.
- Create-order button: 56-dp circle; open state in an OverlayPortal so the
  scrim covers the whole screen, bottom bar included, with equal full-width
  Buy/Sell buttons; scrim, ✕ and back close it.
- Bottom bar restyled (shared by Book, Trades and Chat) with short labels.
- OrderBookPalette moves to its own file with the handoff's tokens and a
  derived light mapping; textFaint lightened to pass AA; contrast test
  rewritten for every text role.
- Outfit (UI) and Manrope (figures) bundled as assets with their OFL
  licences registered at startup — no runtime font fetch.
- l10n: new sort, card, empty-state and bottom-bar strings in all five
  locales; tab/filter labels in sentence case; unused offersCount,
  reasonJustPublished, buyLabel and sellLabel removed.

Walkthrough

The pull request redesigns the order book with new fonts, palette tokens, sorting, filtering, segmented navigation, masonry cards, updated empty states, localized labels, and custom shared controls. It also adds license registration and extensive widget and provider tests.

Changes

Visual foundation

Layer / File(s) Summary
Typography, palette, and license foundation
assets/fonts/*, lib/core/*, pubspec.yaml, test/core/*
Outfit and Manrope fonts are bundled and licensed. AppFonts and OrderBookPalette provide shared theme tokens. Font licenses register during startup. Palette contrast tests cover dark and light roles.

Order-book behavior

Layer / File(s) Summary
Order filtering, sorting, and highlight rules
lib/features/home/providers/*, lib/features/home/widgets/order_sort_sheet.dart, lib/shared/widgets/order_filter.dart, test/features/home/order_*test.dart
Tab membership is centralized. Sorting and filter state remain provider-driven. The order sort sheet updates orderSortProvider. Highlight reasons now contain only best-premium and most-reputable states.

Home order-book presentation

Layer / File(s) Summary
Home order-book presentation
lib/features/home/screens/*, lib/features/home/widgets/*, lib/l10n/*.arb, test/features/home/*
The home screen uses segmented Buy/Sell controls, animated switching, explicit loading and error states, masonry grids, redesigned order cards, and filter-aware empty states. Localization and widget coverage are updated for the new presentation.

Shared controls

Layer / File(s) Summary
Shared navigation and add-order controls
lib/shared/widgets/*, test/shared/widgets/*
The add-order menu now uses an OverlayEntry with route-scoped semantics. The bottom navigation bar is custom-rendered and palette-driven. Notification indicators accept configurable styling.

Add a newest tie-break test for reputation sorting.

OrderSort.bestReputation falls back to newest order after rating and trade count. Add equal rating and tradeCount values with different minutesAgo values, then assert the newer order is first. This covers the fallback required by the repository testing convention.

- Line 89: Update OrderBookList so its multi-column grid does not force
OrderListItem cards into the fixed childAspectRatio of 1.1; use a
variable-height layout or a sufficiently tested extent that accommodates
wrapping content at 200% text scale. Add coverage for both two- and three-column
layouts at that text scale, preserving the existing card content and column
behavior.

- Line 169: Update the _OpenMenu overlay returned by LayoutBuilder to wrap the
open-menu content in BlockSemantics with a separate semantics scope, ensuring
underlying route and bottom-navigation controls are excluded while the menu
remains accessible.

- Route a tapped card from the order itself (routeForOrder: own order,
  else its side), never from the selected tab: during the 150 ms tab
  cross-fade the outgoing list is still tappable while the tab already
  names the other side. A tap on an order that has since left the book
  does nothing.
- Tablet/desktop grid is now a masonry grid (flutter_staggered_grid_view):
  cards keep their natural height instead of a fixed 1.1 tile ratio that
  overflowed on long localized copy or large text. The index callback
  still moves keyed cards on re-sort. Covered at 2 and 3 columns, 200% text.
- The open create-order menu is now its own OverlayEntry above the route,
  wrapped in BlockSemantics with a route-like scope. An OverlayPortal child
  is attached for semantics where the button sits — before the bottom bar —
  so blocking from there emptied the tree, menu included; from a separate
  entry it hides the page and bottom bar and keeps Buy/Sell/Close reachable.
- Test the newest-first tie-break of the reputation sort.

Review round 1 addressed in 5e4744a: the three inline comments are answered in their threads. The nitpick is done too: order_sort_test.dart now covers the newest-first tie-break when rating and trade count are equal. flutter analyze is clean and flutter test passes (446).

- Buy/Sell tabs: the active tint sits under the Material, so the ripple
  paints over it instead of beneath it.
- Create-order menu closes when the screen changes size while open (after
  the frame), instead of leaving the ✕ and Buy/Sell where the button was.
- Empty state blames the filters — and offers to clear them — only when
  the tab has orders they hide (new tabHasOrdersProvider); an empty tab
  gets the generic line. The tab-membership rule is shared with
  filteredOrdersProvider.
- Fixed-sats caption is one sentence with a {sats} placeholder
  (orderFixedAmount) split around the figure to style it, instead of a
  prefix glued to it, so locales can reorder words.
- Filter row hides the order count and sort caption while the book is
  loading or failed.
- Order list skeleton moves to features/home: shared/ no longer imports a
  feature.
- App-bar hamburger gets a 48-dp touch target, glyph position unchanged.
- AppFonts.figures documents that only weights 500–700 are bundled.
- Doc comments no longer point at the untracked design handoff folders.

Comment thread lib/shared/widgets/add_order_button.dart Outdated
The open menu gets a FocusScope, so Tab cycles through Buy, Sell and Close
instead of reaching controls hidden behind the scrim. The button owns the
scope node and moves focus into it after the frame (autofocus does not
take while the route's scope holds focus), then hands focus back to what
held it before when the menu closes. The scope adds no semantics, so the
BlockSemantics boundary is unchanged.
