TabData class

The tab data.

The text displayed on the tab is defined by text parameter.

The optional value parameter allows associate the tab to any value.

The optional content parameter defines the content of the tab.

The closable parameter defines whether the Close button is visible.

The buttons parameter allows you to define extra buttons in addition to the Close button.

The keepAlive parameter indicates whether to keep the tab content widget in memory even if it is not visible. Indicated to prevent loss of state due to tree change by tab selection. If enabled, the Widget will continue to be instantiated in the tree but will remain invisible. The default value is FALSE. A more efficient alternative is to keep the data in TabData's value parameter as long as the TabbedViewController is being kept in the state of its class.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
toString() → String
A string representation of this object.
