copyWith method

@useResult FDialogStyle copyWith({ ImageFilter backgroundFilter(double animation)? = Sentinels.imageFilterFunction, DecorationDelta? decoration, TextStyleDelta? titleTextStyle, TextStyleDelta? bodyTextStyle, EdgeInsetsGeometryDelta? insetPadding, Future<void> slidePressHapticFeedback()?, FDialogMotionDelta? motion, })

Returns a copy of this FDialogStyle with the given properties replaced.

See customizing widget styles.

Parameters

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

This is typically combined with a transparent/translucent background to create a glassmorphic effect.

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),
);

• FDialogStyle.decoration - The decoration.
• FDialogStyle.titleTextStyle - The title's TextStyle.
• FDialogStyle.bodyTextStyle - The body's TextStyle.
• FDialogStyle.insetPadding - The inset padding.
• FDialogStyle.slidePressHapticFeedback - The haptic feedback for when the user slides from one action to another.
• FDialogStyle.motion - Motion-related properties.
