StateSet<T extends StatefulWidget> mixin

Manages the collection of State objects extended by the SetState class

Superclass Constraints

Properties

context → BuildContext
The location in the tree where this widget builds.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
mounted → bool
Whether this State object is currently in a tree.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
widget → T
The current configuration.
no setterinherited

Methods

activate() → void
In case the State object is reinserted in the Widget tree.
override
build(BuildContext context) → Widget
Describes the part of the user interface represented by this widget.
inherited
deactivate() → void
In case there is a 'hot reload' for example and the State object is re-created.
override
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
didChangeDependencies() → void
Called when a dependency of this State object changes.
inherited
didUpdateWidget(covariant T oldWidget) → void
Switch out the old StatefulWidget object with the new one.
override
dispose() → void
Remove objects from the static Maps if not already removed. add this function to the State object's dispose function
override
initState() → void
Adds StatefulWidget to a static map add this function to the State object's initState() function. Adds State object to a static map
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reassemble() → void
Called whenever the application is reassembled during debugging, for example during hot reload.
inherited
refresh() → void
'Refresh' the State object's widget tree
setState(VoidCallback fn) → void
Notify the framework that the internal state of this object has changed.
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
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
inherited

Static Properties

lastContext → BuildContext?
Retrieve the latest context (i.e. the last State object's context)
no setter
root → StateSet<StatefulWidget>?
Retrieve the first StateSet object
no setter

Static Methods

of<T extends StatefulWidget, U extends State<StatefulWidget>>() → U?
Retrieve the type of State object by its StatefulWidget Returns null if not found
rebuildState(StatefulWidget? widget) → bool
Call setState() from the State object from the specified StatefulWidget Return true if successful Usually called in the StatefulWidget passing 'this' as a parameter.
refreshState(StatefulWidget? widget) → bool
Call setState() from the State object from the specified StatefulWidget Return true if successful Usually called in the StatefulWidget passing 'this' as a parameter.
setStateOf(StatefulWidget? widget, VoidCallback? fn) → bool
Calls the setState() of the State objet from the specified StatefulWidget passing the specified function. Return true if successful. Usually called in the StatefulWidget passing 'this' as a parameter.
stateIn(StatefulWidget? widget) → StateSet<StatefulWidget>?
Return the State object used by the specified StatefulWidget object. Usually called in the StatefulWidget passing 'this' as a parameter.
stateOf<T extends StatefulWidget>() → StateSet<StatefulWidget>?
Retrieve the State object by its StatefulWidget Returns null if not found
to<T extends State<StatefulWidget>>() → T?
Retrieve the State object by type Returns null if not found Note: If there's multiple State objects of the same type, will return the 'last' state object added to the Map, _setStates"
