TouchScale class
A widget that scales down its child when pressed and triggers a callback on tap. Commonly used to enhance tap interactions with visual responsiveness.
Example
TouchScale(
onPress: () => print("Pressed!"),
child: Text("Hello, World!"),
)

Properties
- behavior → TouchScaleBehavior?
-
Resolves the scale factor to apply during a press interaction.
e.g. a value of 0.9 scales the widget to 90% of its original size.
final
- callPhase → TouchScaleCallPhase?
-
Defines the phase in which a touch scale callback is triggered.
final
- child → Widget
-
The widget below this widget in the tree that will be scaled.
final
- curve → Curve?
-
The curve of the forward animation when scaling down.
final
- duration → Duration?
-
The duration of the forward (scale-down) animation.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- onPress → VoidCallback
-
Called when the gesture is accepted and the press is confirmed.
final
- previewDuration → Duration?
-
The duration to wait before showing the scale preview effect.
If the gesture is rejected before this duration passes,
the effect will not appear.
final
- resolver → TouchScaleResolver?
-
The scale factor to apply when pressed. For example,
0.9 means 90% of the original size.
final
- reverseCurve → Curve?
-
The curve of the reverse animation when scaling back to original size.
final
- reverseDuration → Duration?
-
The duration of the reverse (scale-up) animation.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
