book_page_flip 0.1.0

A smooth, efficient open-book page-turn widget. Drag or animate pages with a realistic 3D page curl, a soft shadow, and a natural-feeling turn.

0.1.0

• Initial release.
• BookFlip widget with drag-to-turn 3D page flip over a single packed texture.
• BookFlip.builder and BookFlip.widgets: build pages from ANY widgets (text, images, whole layouts), captured and disposed for you — no ui.Image lifecycle to manage.
• pageLabel: stamp a custom page number (or any widget) onto every page, baked into the page at no per-frame cost.
• BookFlipCurl: direct control of the page-curve trajectory — bend, foldTilt and droop — independent of the paper, with copyWith and lerp.
• BookFlipEffects: turn each visual layer (gloss, grain, cast shadow, spine shadow, edge line, translucency) on or off individually.
• BookFit and pageAspectRatio: fits any layout (fixed, flex, scrollable) and keeps the pages' true shape — no distortion, never throws under any constraints.
• maxTextureDimension and meshResolution for device tuning. The atlas adapts to the GPU's real texture limit (retrying smaller if rejected), and mesh smoothness can be raised for large or high-density screens.
• BookFlipController for programmatic turns by spread (nextSpread, previousSpread, goToSpread) or by page (goToPage), and for observing currentSpread, currentPage, totalSpreads, totalPages, flipProgress and isAnimating.
• BookFlipPhysics for tuning the spring and commit behavior.
• BookFlipMaterial for the paper's feel — stiffness, weight, gloss, translucency and edge thickness — with two ready-made papers (paper, the matte default, and glossy magazine), plus lerp and copyWith.
• onSpreadChanged / onFlipStart / onFlipEnd callbacks.
