CardMorphTween class abstract final

Pure-function interpolation helpers mapping vertical progress (0.0–1.0) to concrete visual property values.

All methods are static, side-effect free, and deterministic: visualProperty = f(progress). No animation widgets involved.

Internally delegates to MorphEngine. The public API is preserved for backward compatibility.

Static Methods

adjacentCardOpacity() → double

Opacity for adjacent cards.

adjacentCardScale({double activeScale = 1.0}) → double

Scale factor for adjacent (non-active) cards in the carousel.

cardContentOpacity(double progress) → double

Card-mode content opacity. Fades out as we approach fullscreen. Visible from progress 0.0 to ~0.6, then fades.

fullscreenContentOpacity(double progress) → double

Fullscreen-mode content opacity. Fades in from ~0.5 to 1.0.

morphBackgroundBlur(double progress, {double maxBlur = 8.0}) → double

Background blur sigma. At progress 0.0 → 0.0, at 1.0 → maxBlur.

morphBackgroundOpacity(double progress, {double maxOpacity = 0.6}) → double

Background barrier opacity (scrim darkening). At progress 0.0 → 0.0, at 1.0 → maxOpacity.

morphBackgroundScale(double progress, {double minScale = 0.92}) → double

Background scale (slight zoom-out effect). At progress 0.0 → 1.0, at 1.0 → minScale.

morphElevation(double progress, {double maxElevation = 12.0}) → double

Shadow elevation. At progress 0.0 → maxElevation, at 1.0 → 0.0.

morphHeight(double progress, {double cardHeightFraction = 0.75}) → double

Card height as fraction of available height. At progress 0.0 → cardHeightFraction, at 1.0 → 1.0 (fullscreen).

morphRadius(double progress, {double maxRadius = 28.0}) → double

Corner radius. At progress 0.0 → maxRadius, at 1.0 → 0.0.

morphWidth(double progress, {double cardWidthFraction = 0.85}) → double

Card width as fraction of available width. At progress 0.0 → cardWidthFraction, at 1.0 → 1.0 (fullscreen).

thumbnailOpacity(double progress) → double

Thumbnail selector bar opacity. Visible at progress < 0.4, fades out linearly. opacity = 1 - progress * 2 (clamped to 0.0–1.0).

thumbnailTranslateY(double progress, {double maxShift = 60.0}) → double

Thumbnail bar vertical offset for slide-out effect. Moves downward as card expands.
