Showing only one widget by active case. Based on AnimatedSwitcher.

Inheritance

Constructors

CaseWidget({Key? key, required T? activeCase, required Map<T, WidgetBuilder> builders, WidgetBuilder? placeholder, CrossTransition? transition, Map<T, CrossTransition>? transitions, bool autoKey = true, bool reverseOrder = false, bool reverseAnimation = false, bool soft = true})
Resolves what to show by activeCase. Every Widget has custom case T key and is build only if case is active. Only one Widget is shown at given time.

Properties

activeCase → T?
Currently active case.
final
activeTransition → CrossTransition
Returns transition of activeCase.
no setter
autoKey → bool
final
builders → Map<T, WidgetBuilder>
Set of Widget builders. Every builder is stored under own case T key.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
placeholder → WidgetBuilder?
Placeholder if activeCase is 'null' or not found in builders.
final
reverseAnimation → bool
final
reverseOrder → bool
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
soft → bool
final
transition → CrossTransition?
Default transition from one widget to another. By default CrossTransition.fade is used.
final
transitions → Map<T, CrossTransition>?
Specific CrossTransition for every case. If case is not included, then default transition is used.
