override
createState ()
→ ControlState <_ControlWidgetBase >

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
init (CoreContext context )
→ void
Initial widget initialization.
Use your mixins here.

Called whenever Widget requests update.
Check State.didUpdateWidget for more info.
Just callback from State.
inherited
rebuild (CoreContext context )
→ Widget
Abstract rebuild implementation - override with proper build in concrete class.
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
