Constants

themeAnimationDuration → const Duration

Theme-switch animation length (flutter-patterns § Theming: animated transition via ThemeExtension.lerp, ~200 ms — long enough to read as deliberate, short enough to never gate interaction).

Properties

amoledDarkTheme → ThemeData

Dark theme, AMOLED true-black variant (Settings → Appearance opt-in).

final

darkTheme → ThemeData

Dark theme (app default) — the refreshed design's dim dark.

final

lightTheme → ThemeData

Light theme.

final

Functions

buildTheme(WalletColors colors, {TextTheme? textTheme, Iterable<ThemeExtension<ThemeExtension>> extensions = const []}) → ThemeData

Build a complete ThemeData from a WalletColors scheme.

overlayStyleFor(WalletColors colors) → SystemUiOverlayStyle

System status-bar / nav-bar overlay style for a given scheme. Light theme → dark icons (visible on cream); dark theme → light icons. Applied via the AppBar theme AND globally in the MaterialApp builder (AppBar-less screens get no appBarTheme.systemOverlayStyle).

walletTextScale(WalletColors colors) → TextTheme

The wallet UI's type scale, with NO font family (FR-49 W-3, W-9): sizes, weights and tracking from the refreshed design (Relim design-refresh spec §3.6), colours from colors. Every slot the SDK's widgets read is defined, so a host that supplies only some styles still gets the SDK's sizes for the rest, never Material's defaults.
