Methods

addListener(void listener()) → void: Register a closure to be called when the object changes.
override
applyAttribute(TextAttribute attribute) → void: Available on SpannedTextEditingController, provided by the SpannedTextEditingControllerExtension extension
Apply an attribute to the current selection.
buildTextSpan({required BuildContext context, TextStyle? style, required bool withComposing}) → TextSpan: Builds TextSpan from current editing value.
override
clear() → void: Set the value to empty.
override
clearComposing() → void: Set the composing region to an empty range.
override
copy() → SpannedTextEditingController: Create a new spanned text editing controller with the same state as this one.
copyWith({TextAttribute? compositionAttribute, ProcessTextValue? processTextValue, String? text, SpanList? spans, bool? hasMarkerCharacters}) → SpannedTextEditingController: Create a new spanned text editing controller with the same state as this one, but with the given fields replaced with the new values.
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).
override
getAppliedSpansWithType<T extends TextAttribute>() → Iterable<AttributeSpan>: Available on SpannedTextEditingController, provided by the SpannedTextEditingControllerExtension extension
Get all attribute spans of type T applied to the current selection.
getAppliedSpansWithUnsafeType(Type type) → Iterable<AttributeSpan>: Available on SpannedTextEditingController, provided by the SpannedTextEditingControllerExtension extension
Get all attribute spans of type type applied to the current selection.
isApplied(TextAttribute attribute) → bool: Available on SpannedTextEditingController, provided by the SpannedTextEditingControllerExtension extension
Determines if attribute is applied to the full selection (for a ranged selection) or would be applied on insertion (for a collapsed selection).
isSelectionWithinTextBounds(TextSelection selection) → bool
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
override
removeListener(void listener()) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
override
setOverride(TextAttribute attribute, OverrideType type) → void: Override whether or not an attribute will be applied on the next insertion.
toggleAttribute(TextAttribute attribute) → bool: Available on SpannedTextEditingController, provided by the SpannedTextEditingControllerExtension extension
Toggle an attribute for the current selection.
toString() → String: A string representation of this object.
override

Operators

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

Static Methods

diffStrings(String oldText, String newText, int cursor) → StringDiff: Diff two strings under the assumption that at most one insertion and one deletion took place, and both happened at the same index, after which the cursor was at index cursor in the new string.
