Properties

alignment → FlexAlignment
Main axis flex alignment.
finalinherited
axis → Axis

finalinherited
controlOverrideChild → bool
Adds extra controls before consulting the child.
finalinherited
crossAxisAlignment → CrossAxisAlignment
Cross axis flex alignment.
finalinherited
crossAxisTight → bool
Whether to be tight to children in the cross axis.
finalinherited
dependency → dynamic
Provider dependency; when it changes this component's state is invalidated.
finalinherited
extraControl → bool Function(ProviderContainer container, KeyInput key, int getState(ProviderContainer), void setState(ProviderContainer container, int update(int)), int length)?
Adds extra controls.
finalinherited
focused → bool
Whether to pass focused to selected child.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
key → String?
Key used to differentiate the states of different instances of this component.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
selectableChildren → Iterable<Renderable Function(bool focused)>
Children which can be selected (i.e. not wrapped in SkipSelect).
no setterinherited
startingState → int
Starting selected child.
finalinherited
stateProvider → dynamic
Reference to this class's state provider. Provide a static final StateProvider of the correct type, using key if relevant.
no setterinherited

Methods

build(ProviderContainer container) → Renderable
Return a Renderable which is to be displayed.
inherited
getSize(ProviderContainer container, Axis axis, int crossSize) → int?
Report this item's intrinsic size, or null if it has none.
inherited
getState(ProviderContainer container) → int

inherited
render(ProviderContainer container, int width, int height) → AxelMap
