AnimatedChildValueBuilder<T> typedef

AnimatedChildValueBuilder<T> = Widget Function(BuildContext context, T oldValue, T newValue, double t, Widget? child)

A callback that builds a widget with raw animation progress information.

Used by AnimatedValueBuilder.raw to provide complete animation state including the old value, new value, and current progress t between them (0.0 to 1.0). This gives maximum control for custom interpolation and transition effects.

Implementation

typedef AnimatedChildValueBuilder<T> = Widget Function(
    BuildContext context, T oldValue, T newValue, double t, Widget? child);
