<itemvalue="Clip with anti-aliasing and saveLayer immediately following the clip. This mode not only clips with anti-aliasing, but also allocates an offscreen buffer. All subsequent paints are carried out on that buffer before finally being clipped and composited back. This is very slow. It has no bleeding edge artifacts (that [antiAlias] has) but it changes the semantics as an offscreen buffer is now introduced. (See https:github.comflutterflutterissues18057issuecomment-394197336 for a difference between paint without saveLayer and paint with saveLayer.) This will be only rarely needed. One case where you might need this is if you have an image overlaid on a very different background color. In these cases, consider whether you can avoid overlaying multiple colors in one spot (e.g. by having the background color only present where the image is absent). If you can, [antiAlias] would be fine and much faster. See also: [antiAlias], which is much faster, and has similar clipping results."/>
<itemvalue="Clip with anti-aliasing. This mode has anti-aliased clipping edges to achieve a smoother look. It' s much faster than [antiAliasWithSaveLayer], but slower than [hardEdge]. This will be the common case when dealing with circles and arcs. Different from [hardEdge] and [antiAliasWithSaveLayer], this clipping may have bleeding edge artifacts. (See https:fiddle.skia.orgc21cb4c2b2515996b537f36e7819288ae for an example.) See also: [hardEdge], which is a little faster, but with lower fidelity. [antiAliasWithSaveLayer], which is much slower, but can avoid the bleeding edges if there's no other way. [Paint.isAntiAlias], which is the anti-aliasing switch for general draw operations."/>
<itemvalue="Clip, but do not apply anti-aliasing. This mode enables clipping, but curves and non-axis-aligned straight lines will be jagged as no effort is made to anti-alias. Faster than other clipping modes, but slower than [none]. This is a reasonable choice when clipping is needed, if the container is an axis- aligned rectangle or an axis-aligned rounded rectangle with very small corner radii. See also: [antiAlias], which is more reasonable when clipping is needed and the shape is not an axis-aligned rectangle."/>
<itemvalue="No clip at all. This is the default option for most widgets: if the content does not overflow the widget boundary, don't pay any performance cost for clipping. If the content does overflow, please explicitly specify the following [Clip] options: [hardEdge], which is the fastest clipping, but with lower fidelity. [antiAlias], which is a little slower than [hardEdge], but with smoothed edges. [antiAliasWithSaveLayer], which is much slower than [antiAlias], and should rarely be used."/>
