fluent_2_fonts #

Platform font facade for Fluent 2 Flutter packages. Each platform descriptor is published as a separate package:

• fluent_2_fonts_web — dynamically loaded Selawik, bundled only on Web
• fluent_2_fonts_windows — dynamically loaded Selawik, bundled only on Windows
• fluent_2_fonts_macos — native San Francisco system-family descriptors
• fluent_2_fonts_ios — native San Francisco system-family descriptors
• fluent_2_fonts_android — native Roboto family descriptor

The Web and Windows packages intentionally own separate copies of Selawik. Flutter 3.41's platform-specific asset filtering ensures that a target includes only its own copy. Mobile and macOS builds include no Selawik files.

The facade uses a Dart conditional import to compile the Web loader only for Web and the native implementation only for native builds. Dart has no compile-time conditions for individual native operating systems, so native font binaries are selected by Flutter's platforms asset metadata instead. The facade does not re-export the implementation packages; consumers and core use one stable FluentFonts API.

FluentApp loads the required family automatically. Applications that need the font before constructing their root widget can preload it explicitly:

WidgetsFlutterBinding.ensureInitialized();
await FluentFonts.ensureLoaded();
runApp(const FluentApp(home: Home()));

Flutter can tree-shake statically referenced icon glyphs, but ordinary text can arrive dynamically at runtime. The text faces therefore remain intact; only the three weights used by Fluent's Web and Windows ramps are bundled automatically.
