copyWith method
Returns a copy of this FSheetStyle with the given properties replaced.
Where possible, it is strongly recommended to use the CLI to generate a style and directly modify the style.
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),
);
enterDuration
The entrance duration. Defaults to 200ms.
exitDuration
The exit duration. Defaults to 200ms.
flingVelocity
The minimum velocity to initiate a fling. Defaults to 700.
Contract
Throws an AssertionError if the value is not positive.
closeProgressThreshold
The threshold for determining whether the sheet is closing. Defaults to 0.5.
Contract
Throws an AssertionError if the value is not in the range [0, 1].
