SentientAnimatedOpacity class

A reactive animated opacity widget that adapts its opacity behavior based on the user's emotional state.

SentientAnimatedOpacity functions as a drop-in replacement for Flutter's AnimatedOpacity but introduces emotion-aware timing and opacity adjustments. It automatically tunes the transition duration and curve based on the active EmotionTheme provided by the AdaptationManager.

This widget ensures that visibility changes feel consistent with the user's emotional context—for example, faster and bouncier for enjoyment, or slower and smoother for sadness.

Features

  • Emotion-aware transition duration and easing curves.
  • Subtle opacity modification based on emotion (e.g., ensuring minimum visibility for fear/anger).
  • Supports custom overrides for duration and curve.

Example Usage

SentientAnimatedOpacity(
  opacity: isVisible ? 1.0 : 0.0,
  child: Text('Now you see me'),
)
