computeState method

LiquidMorphState computeState({ required double finalDx, required double finalDy, double horizontalOffset = 0.0, double verticalOffset = 0.0, double scaleDelta = 1.0, bool? adaptiveDamping, bool? isClosing, })

Computes the current LiquidMorphState for the given layout geometry.

Call this once per frame from your AnimatedBuilder or addListener callback to get pre-calculated render values.

• finalDx / finalDy — target displacement from trigger center to menu center, in logical pixels.
• horizontalOffset / verticalOffset — screen-edge clamping corrections from the menu positioning logic.
• scaleDelta — geometric scale ratio (see LiquidMorphPhysics.computeScaleDelta). Values > 1.5 engage adaptive damping. Defaults to 1.0 (unchanged baseline behaviour) for backward compatibility.
• adaptiveDamping — explicit override; when null (default), inferred from scaleDelta.
• isClosing — explicit override; when null (default), inferred from this controller's own _isClosing state.

Implementation

LiquidMorphState computeState({
  required double finalDx,
  required double finalDy,
  double horizontalOffset = 0.0,
  double verticalOffset = 0.0,
  double scaleDelta = 1.0,
  bool? adaptiveDamping,
  bool? isClosing,
}) {
  return LiquidMorphPhysics.compute(
    rawValue: _animationController.value,
    finalDx: finalDx,
    finalDy: finalDy,
    horizontalOffset: horizontalOffset,
    verticalOffset: verticalOffset,
    scaleDelta: scaleDelta,
    adaptiveDamping: adaptiveDamping,
    isClosing: isClosing ?? _isClosing,
  );
}
