I have a container with a column inside it and its wrapped with a SingleChildScrollView widget.
I want to disable this scroll splash animation that comes when we reach the end of the scroll view.
This is what my widget tree looks like for this one.
Container - with rounded border
|
SingleChildScrollView
|
Column
|
Some widgets in children
Because this comes over the rounded border of the container I want to disable it.
Apoorv, google has many solutions to this question, please check this page for a solution to your problem.
try the following
MaterialApp(
builder: (context, child) {
return ScrollConfiguration(
behavior: MyBehavior(),
child: child,
);
},
home: new MyHomePage(),
);
and define custom scroll behavior like this
class MyBehavior extends ScrollBehavior {
#override
Widget buildViewportChrome(
BuildContext context, Widget child, AxisDirection axisDirection) {
return child;
}
}

I've recently developed comment view below the detail posts.
Like the image I attached, I'd like to show images for each comment but the image Container should be transparent to see the last comment.
But I think Scaffold doesn't allow bottomSheet to have transparent children.
Are there anyone having an idea to solve this problem?
class PostDetail extends StatelessWidget {
final int maxRenderImgCnt = 4;
final Post post;
PostDetail(this.post);
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: CustomAppBar( ... ),
body: SingleChildScrollView( ... ),
bottomSheet: CommonTextField(onTap: null, editTarget: null),
You can wrap the widget with an opacity widget but there is also another way which is more efficient even for changing it later, that is the ThemeData widget:
bottomSheetTheme: BottomSheetThemeData(
backgroundColor: Colors.black.withOpacity(0),
),
I have made PageView, set physics to NeverScrollableScrollPhysics to disabled scroll and implements it by buttons. But when I call controller.animateToPage(/* ... */), my PageView animated with scroll glow. How to disabled this behaviour? Or this is bug of Flutter itself?
To disable Scroll glow, create a class that extends ScrollBehavior
class DisableScrollGlowBehavior extends ScrollBehavior {
#override
Widget buildViewportChrome(
BuildContext context, Widget child, AxisDirection axisDirection) {
return child;
}
}
Then wrap your scrollable List widget with ScrollConfiguration widget using the behavior of the class created.
ScrollConfiguration(
behavior: DisableScrollGlowBehavior(),
child: ListView(
children: [],
),
)
I am trying to implement a Scroll Widget in Flutter but not able to implement it.
I saw many tutorials but they have implemented scroll widget with ListView or Grid View.
In my case, I have Register page with multiple Text Inputs and Buttons. In this case, my page is not scrolling down please help someone.
div{
Scroll Widget on the Register page.
}
like this
class ExampleScroll extends StatefulWidget {
#override
_ExampleScrollState createState() => _ExampleScrollState();
}
class _ExampleScrollState extends State<ExampleScroll> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: SingleChildScrollView(
child: Container(),
),
);
}
}
Please wrap with a SingleChildScrollView Widget.
Like this...
class AppDashBoard extends StatelessWidget {
#override
Widget build(BuildContext context) {
return SingleChildScrollView(
child: Container(
child: Text('It Scrollable'),
),
);
}
}
You can use SingleChildScrollView for scrolling like this.
SingleChildScrollView(
child:Column(...)
)
You can use SingleChildScrollView and provide scrolling contents as its child
for more you can find on the documentation
https://api.flutter.dev/flutter/widgets/SingleChildScrollView-class.html
Eg:
SingleChildScrollView(
// scrollable contents as child
child:Column(...)
)
Screenshot of the code and it's result:
Hi, I have StatelessWidget which has Container returning in its build method and the Text widget as a child widget. But it's look and feel is not as expected. Why is the yellow underline and how can I remove it?
I tried replacing the Container with Stack, Column and Row nothing change.
Because of you havent wrap your Text widget with a material widget. You can wrap with a Scaffold or with Material widget with color property as you want.
Example:
Scaffold(body: Center(child: Text("Here is the text")))
or:
Material(color: Colors.white, child: Center(child: Text("Here is the text")))
Every screen should have a scaffold widget
#override
Widget build(BuildContext context) {
return Scaffold(
body:Container(
child:Text("your text"),
),
);
By default, flutter adds a overscroll effect on ListView/GridView/... on ios
I would like to remove this effect entirely or on one specific scrollable.
What can I do ?
You don't need to do those fancy stuff if you only want to remove overscroll behavior on iOS. Simply, use:
ListView(
physics: ClampingScrollPhysics(),
)
I found this answer (https://stackoverflow.com/a/51119796/5869913) and just added information about deleting overscroll effect.
The overscroll effect comes from BouncingScrollPhysics added by ScrollBehavior
To remove this effect, you need to specify a custom ScrollBehavior and override getScrollPhysics method. For that, simply wrap any given part of your application into a ScrollConfiguration with the desired ScrollBehavior.
The following ScrollBehavior will remove the overscroll effect entirely :
class MyBehavior extends ScrollBehavior {
#override
ScrollPhysics getScrollPhysics(BuildContext context) => ClampingScrollPhysics();
}
You can also remove glow effect with override of method buildViewportChrome like this:
#override
Widget buildViewportChrome(BuildContext context, Widget child, AxisDirection axisDirection) => child;
To remove the overscroll on the whole application, you can add it right under MaterialApp :
MaterialApp(
builder: (context, child) {
return ScrollConfiguration(
behavior: MyBehavior(),
child: child,
);
},
home: MyHomePage(),
);
To remove it on a specific ListView, instead wrap only the desired ListView :
ScrollConfiguration(
behavior: MyBehavior(),
child: ListView(
...
),
)
or just set physics: ClampingScrollPhysics() in the ListView
