FDialogRouteStyleDelta.delta constructor

const FDialogRouteStyleDelta.delta({ ImageFilter Function(double)? barrierFilter()?, FDialogRouteMotionDelta? motion, })

Creates a partial modification of a FDialogRouteStyle.

Parameters

• FDialogRouteStyle.barrierFilter - An optional callback that takes the current animation transition value (0.0 to 1.0) and returns an ImageFilter that is used as the barrier. Defaults to null.

Examples

// Blurred
(animation) => ImageFilter.blur(sigmaX: animation * 5, sigmaY: animation * 5);

// Solid color
(animation) => ColorFilter.mode(Colors.white.withValues(alpha: animation), BlendMode.srcOver);

// Tinted
(animation) => ColorFilter.mode(Colors.white.withValues(alpha: animation * 0.5), BlendMode.srcOver);

// Blurred & tinted
(animation) => ImageFilter.compose(
  outer: ImageFilter.blur(sigmaX: animation * 5, sigmaY: animation * 5),
  inner: ColorFilter.mode(Colors.white.withValues(alpha: animation * 0.5), BlendMode.srcOver),
);

• FDialogRouteStyle.motion - Motion-related properties.

Implementation

const factory FDialogRouteStyleDelta.delta({
  ImageFilter Function(double)? Function()? barrierFilter,
  FDialogRouteMotionDelta? motion,
}) = _FDialogRouteStyleDelta;
