Scroll

VelocityX includes widgets which can be used to add scroll behaviour.

tip

You can either use VxScrollVertical, VxScrollHorizontal or SingleChildScrollView.

VxScrollVertical

VxScrollVertical is a widget that can be used to create vertical scroll behaviour in the application.

Widget build(BuildContext context) {
return VxScrollVertical(
physics: AlwaysScrollableScrollPhysics(),
child: <Widget>[
'First Text'.text.make(),
'Second Text'.text.make()
].vStack(),
);

Using Extension Method

Widget build(BuildContext context) {
return [
'First Text'.text.make(),
'Second Text'.text.make()
].vStack().scrollVerticial(physics: AlwaysScrollableScrollPhysics()),
;

Above code creats a vertical scrollable list with two widgets.

VxScrollVertical Constructor

const VxScrollVertical({
Key key,
this.controller,
this.physics,
this.padding,
this.child,
}) : super(key: key)

VxScrollVertical Properties

  • Key key : A Key is an identifier for Widgets, Elements and SemanticsNodes. A new widget will only be used to update an existing element if its key is the same as the key of the current widget associated with the element.

  • Widget child : The widget that scrolls. This widget can only have one child. To lay out multiple children, let this widget's child be a widget such as Row, Column, or Stack, which have a children property, and then provide the children to that widget.

  • EdgeInsetsGeometry padding : The amount of space by which to inset the child..

  • ScrollController controller : An object that can be used to control the position to which this scroll view is scrolled. It can also be used to read the current position, set the initial position or jump to a particular position.

  • ScrollPhysics physics: Determines the physics of a Scrollable widget. The most common scroll physics are AlwaysScrollableScrollPhysics, BouncingScrollPhysics, NeverScrollableScrollPhysics. To know more visit Flutter Dev Website.

VxScrollHorizontal

VxScrollHorizontal is a widget that can be used to create horizontal scroll behaviour in the application.

Widget build(BuildContext context) {
return VxScrollHorizontal(
physics: AlwaysScrollableScrollPhysics(),
child: <Widget>[
'First Text'.text.make(),
'Second Text'.text.make()
].hStack(),
);

Using Extension Method

Widget build(BuildContext context) {
return [
'First Text'.text.make(),
'Second Text'.text.make()
].hStack().scrollHorizontal(),
;

Above code creats a horizontal scrollable list with two widgets.

VxScrollHorizontal Constructor

const VxScrollHorizontal({
Key key,
this.controller,
this.physics,
this.padding,
this.child,
}) : super(key: key)

VxScrollHorizontal Properties

  • Key key : A Key is an identifier for Widgets, Elements and SemanticsNodes. A new widget will only be used to update an existing element if its key is the same as the key of the current widget associated with the element.

  • Widget child : The widget that scrolls. This widget can only have one child. To lay out multiple children, let this widget's child be a widget such as Row, Column, or Stack, which have a children property, and then provide the children to that widget.

  • EdgeInsetsGeometry padding : The amount of space by which to inset the child..

  • ScrollPhysics physics: Determines the physics of a Scrollable widget. The most common scroll physics are AlwaysScrollableScrollPhysics, BouncingScrollPhysics, NeverScrollableScrollPhysics. To know more visit Flutter Dev Website.
