PlAnimateGrow class

Content unfolding from a point.

const PlAnimateGrow(
  origin: Alignment.topCenter,
  child: PlBox(child: Text('Sort, group and column visibility.')),
)

The difference from PlAnimateZoom is origin and how far it travels: a grow starts close to its final size and can be anchored to an edge, so it reads as something opening out of the thing beside it — a panel out of a toolbar, a card out of the row it belongs to. A zoom starts much smaller and always from the middle.

Short travel is what makes it safe on glass. A sheet growing from 0.8 stays recognisably the same sheet the whole way, and what is behind it never has to resolve a surface a fifth of the size it is about to be.

Creates a grow.

Properties

alternate → bool
Runs every other pass backwards, so a repeat returns instead of jumping.
final
child → Widget
What unfolds.
final
curve → Curve?
The easing curve. The house curve when nothing says otherwise.
final
delay → Duration
How long before it starts. Counted once, before the first run.
final
duration → Duration
How long one run takes.
final
fade → bool
Fades in as it grows.
final
from → double
The scale it starts from, as a multiple of its final size.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
mode → PlassAnimateMode
Whether the content unfolds or folds away.
final
once → bool
With PlassAnimateTrigger.visible, whether it runs only the first time.
final
origin → Alignment
Which point stays put while the rest moves.
final
paused → bool
Holds the animation where it is.
final
play → bool
Runs it, when trigger is PlassAnimateTrigger.manual. Each false → true starts it over.
final
repeat → int?
How many times it runs. null never stops.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
threshold → double
With PlassAnimateTrigger.visible, how much of the widget has to be on screen before it counts as visible, from 0 to 1.
final
trigger → PlassAnimateTrigger
What starts it.
final

Methods

build(BuildContext context) → Widget
Describes the part of the user interface represented by this widget.
override
createElement() → StatelessElement
Creates a StatelessElement to manage this widget's location in the tree.
inherited
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A short, textual description of this widget.
