- currentSizeRect ↔ Rect?
-
getter/setter pairinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
addRatioChangeListener(
RatioChangeListener listener, {Size? initSize, String tag = DEFAULT_TAGNAME}) → void -
inherited
-
addSizeChangeListener(
SizeChangeListener listener, {Size? initSize, String tag = DEFAULT_TAGNAME}) → void -
inherited
-
containsRatioChangeListener(
String tag) → bool -
inherited
-
containsSizeChangeListener(
String tag) → bool -
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
-
notifyRatioChange(
Size size, double newRatio, double? oldRatio) → void -
inherited
-
notifySizeChange(
Rect newSize, Rect? oldSize) → void -
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
removeRatioChangeListener(
RatioChangeListener listener, {String name = DEFAULT_TAGNAME}) → bool -
inherited
-
removeRatioChangeTag(
String tag) → void -
inherited
-
removeSizeChangeListener(
SizeChangeListener listener, {String tag = DEFAULT_TAGNAME}) → bool -
inherited
-
removeSizeChangeTag(
String tag) → void -
inherited
-
toString(
) → String -
A string representation of this object.

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