RichFieldController class Null safety

The controller to be used as a TextEditingController for a TextField

Takes a FocusNode to keep focus on the text being edited. That is particularly useful when using a toolbar to style the selected text. If FocusNode is omitted, whenever the text is styled through a toolbar action, the TextField will loos focus.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
buildTextSpan({required BuildContext context, TextStyle? style, required bool withComposing}) → TextSpan
Traverses the current editing value, splits it based on style, and builds TextSpans If there are no applied spans, it builds a single span containing the editing value's text and the default style
override
clear() → void
Set the value to empty.
inherited
clearComposing() → void
Set the composing region to an empty range.
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
isSelectionWithinTextBounds(TextSelection selection) → bool
Check that the selection is inside of the bounds of text.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent 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.
inherited
updateStyle(TextStyle style) → void
This is the core function of the rich_field_controller. I takes a required style and applies it to the selected text. If there is no active selection, but the focus is still on the TextFiled, then the style is applied to the word containing the cursor.

Operators

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