Methods

addDomElement(BuildContext context) → void

addPostFrameCallback(Function callback) → void

Add a callback which will be executed after initial build or after set state.

cachedInflate(Widget newWidget) → bool

createChildContext({bool copyOldProperties = true, bool copyOldElement = false, bool setChild = true, BuildContext? target}) → BuildContext

deleteDomChildren(int i) → void

executeCallbacks({BuildContext? oldContext}) → void

Execute all the callbacks and clear the callback list.

findState<T>() → T

Looks up the widget tree until it finds a parent of this type or otherwise throws an exception. Make sure that this widget has been appended by the appendTo() method first.

getWidgetContext(Widget newWidget) → BuildContext?

importContext(BuildContext newContext) → void

insertDomChildren(int i, BuildContext context) → void

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

overrideCallbacks() → BuildContext

Create a new context object with the given attribute while overriding callbacks.

replaceDomChildrenWith(int i, BuildContext childContext) → void

shouldReRender(Widget newWidget) → bool

toString() → String

A string representation of this object.
