gnums_utility_widgets library

Classes

Adapter
Adapters provide a mechanism to drive an animation from an arbitrary source. For example, synchronizing an animation with a scroll, controlling an animation with a slider input, or progressing an animation based on the time of day.
AlignedGridView
A scrollable, 2D array of widgets placed according to the aligned layout.
AlignEffect
An effect that animates the target between the specified begin and end alignments (via Align). Defaults to begin=Align.topCenter, end=Align.center.
AnchorKey
Animate
The Flutter Animate library makes adding beautiful animated effects to your widgets simple. It supports both a declarative and chained API. The latter is exposed via the Widget.animate extension, which simply wraps the widget in Animate.
AnimateList<T extends Widget>
Applies animated effects to a list of widgets. It does this by wrapping each widget in Animate, and then proxying calls to all instances. It can also offset the timing of each widget's animation via interval.

BorderShape
BoxShadowEffect
An effect that animates a BoxShadow between begin and end (via DecoratedBox). A value of null for either will be interpreted as a shadow that matches the other shadow but with a zero offset and blurRadius. You can also specify a borderRadius that defines rounded corners for the shadow. Defaults to begin=null, end=BoxShadow(color: Color(0x80000000), blurRadius: 8.0, offset: Offset(0.0, 4.0))

CallbackEffect
An effect that calls a callback function at a particular point in the animation. It includes a boolean value indicating if the animation is playing in reverse.
ChangeNotifierAdapter
Drives an Animate animation from a ChangeNotifier. The valueGetter should provide a value in the range 0-1 when a change occurs.
ChartData
CircleShape
ColorEffect
An effect that animates a Color between begin and end, composited with the target using blendMode (via ColorFiltered). A color value of null will be interpreted as a fully transparent version of the other color. Defaults to begin=null, end=Color(0x800099FF).
ColorMapper
A class that transforms from one color to another during SVG parsing.
ColorPainter
CommonSpace
Content
CrossfadeEffect
An effect that crossfades the incoming child (including preceeding effects) with a new widget (via Stack and FadeTransition). It uses a builder so that the effect can be reused, but note that the builder is only called once when the effect initially builds.

DashedPainter
DashedPainter is a custom painter that draws a dashed line around the child widget. The strokeWidth property defines the width of the dashed border and color determines the stroke paint color. CircularIntervalList is populated with the dashPattern to render the appropriate pattern. The radius property is taken into account only if the borderType is BorderType.RRect. A customPath can be passed in as a parameter if you want to draw a custom shaped border.

CircularIntervalList is populated with the dashPattern to render the appropriate pattern. The radius property is taken into account only if the borderType is BorderType.RRect. A customPath can be passed in as a parameter if you want to draw a custom shaped border.
DottedLine
Draw a dotted line.
DottedScaleXWidget
DownloadProgress
Progress of the file that is being downloaded from the originalUrl.
DropPainter
Effect<T>
An empty effect that all other effects extend. It can be added to Animate, but has no visual effect.
EffectEntry
Because Effect classes are immutable and may be reused between multiple Animate (or AnimateList) instances, an EffectEntry is created to store values that may be different between instances. For example, due to an interval on AnimateList, or from inheriting timing parameters.
EffectList
Simple helper class to build a list of effects via the chained api. Example:
ElevationEffect
An effect that animates a Material elevation shadow between begin and end (via PhysicalModel). You can also specify a shadow color and borderRadius to add rounded corners. It defaults to begin=0, end=8.
