Do you know how make scrollable all mobile page in flutter ? Because if we display some widgets it générâtes an error if it is more of the height of the mobile screen
This would work perfectly. Check it out.
ListView(
children: <Widget>[
// first widget here
Container(
height: 200,
width: MediaQuery.of(context).size.width,
color: Colors.blue,
),
// third widget here
Container(
height: 200,
width: MediaQuery.of(context).size.width,
color: Colors.black,
),
// second widget here
Container(
height: 200,
width: MediaQuery.of(context).size.width,
color: Colors.red,
),
],
),
You can use a ListView
Widget view(){
return ListView(
children: <Widget[
Text("your widgets here"),
SizedBox(height: 20), // you can use these for spacing
]
)
}
Or a SingleChildScrollView
Widget view(){
return SingleChildScrollView(
children: <Widget[
Text("your widgets here"),
SizedBox(height: 20), // you can use these for spacing
]
)
}

In my Flutter app, I have a ListView:
return Scaffold(
body: SafeArea(
child: Container(
color: Colors.blueAccent,
child: ListView(
children: [
Container(
color: Colors.yellow,
height: 100
),
const SizedBox(height: 10),
// How to make this container fill up the remaining height?
Container(
color: Colors.black,
),
],
),
),
),
);
This produces the following view:
Question: How can I make the second box (with black background color) fill up the remaining space? If the content of the box exceeds the remaining space, the ScrollView will enable scrolling.
Is this possible?
There is a better option here using SliverFillRemaining in combination with CustomScrollView instead of a ListView
in your case the code will look like this.
Container(
color: Colors.blueAccent,
child: CustomScrollView(
shrinkWrap: true, // or false
slivers: <Widget>[
SliverToBoxAdapter(
child:Container(
color: Colors.yellow,
height: 100
),),
SliverToBoxAdapter(
child: SizedBox(height: 10),),
// use SliverFillRemaining to make this container fill up the remaining height?
SliverFillRemaining(
hasScrollBody: false, // if using a column, so the widgets in it, doesn't scroll
child:Container( //this container will fill the remaining space in the ViewPort
color: Colors.black,
),
) ,
],
),
),
Fill the remaining space of a ListView means filling the infinite height. I will prefer using Stack as body in this case, hope you can simply archive this.
How can we do without stack?
In this case, we can get the height and use it on Column and using Expanded on inner child that will fill the remaining spaces even for dynamic height.
I prefer using LayoutBuilder to get height.
body: LayoutBuilder(builder: (context, constraints) {
return SafeArea(
child: Container(
color: Colors.blueAccent,
child: ListView(
children: [
SizedBox(
// 1st child of listView
height: constraints.maxHeight,
child: Column(
children: [
Container(color: Colors.yellow, height: 100),
const SizedBox(height: 10),
Expanded(
child: Container(
color: Colors.black,
),
),
],
),
)
],
),
),
);
}),
You can get size and then set a proportion for each...
And set NeverScrollableScrollPhysics() to ensure no slight scrolling, as per below this appears to get what you are seeking.
Widget build(BuildContext context) {
Size _size = MediaQuery.of(context).size;
return Container(
child: Scaffold(
body: SafeArea(
child: Container(
color: Colors.blueAccent,
child: ListView(
physics: NeverScrollableScrollPhysics(),
children: [
Container(color: Colors.yellow, height: _size.height * 0.20),
SizedBox(height: _size.height * 0.10), // How to make this container fill up the remaining height?
Container(
height: _size.height * 0.70,
color: Colors.black,
),
],
),
),
),
));
}
}
Try below code hope its helpful to you. use MediaQuery here. add MediaQuery height to your black container
Refer blog also here for relative to screen size
Container(
color: Colors.blueAccent,
child: ListView(
shrinkWrap: true,
physics: ScrollPhysics(),
children: [
Container(
color: Colors.yellow,
height: 100,
),
const SizedBox(height: 10),
// How to make this container fill up the remaining height?
Container(
color: Colors.black,
height: MediaQuery.of(context).size.height,
),
],
),
),

I'm using a Stack to Positioned one widget on top of an Image.asset widget, but the problem I have is that my whole Stack widget is not scrollable to see the whole content. I wrapped the Stack widget with a SingleChildScrollView but the problem still persists. If I wrap the Stack widget with a Containter and give the height: MediaQuery.of(context).size.height, it's scrollable but I can't still see the whole content of the page. Where is my mistake, that's what I'm wondering? With what widget should I wrap Stack or is there a better way for my problem? In short, I'm stacking a Column on top of an Image and I need the whole Stack widget to be scrollable so I can see the whole content of the Stack widget. Here is the code:
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.grey,
body: SafeArea(
child: SingleChildScrollView(
child: Stack(
overflow: Overflow.visible,
children: [
Image.asset(
'lib/modules/common/images/logo.png',
width: double.infinity,
height: 196.0,
),
Positioned(
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height,
top: 136.0,
child: Column(
children: [
Container(), // some content inside the container
Container(), // // some content inside the container
],
),
),
],
),
),
),
);
}
Thanks in advance for the help!
if you mean to have a image on back and scrollable content at fron check this answer, if not let me know and share a prototype/image that you want.
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.grey,
body: SafeArea(
child: SingleChildScrollView(
child: SizedBox(
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height * 3,
child: Stack(
fit: StackFit.loose,
children: [
Align(
alignment: Alignment.topCenter,
child: Image.asset(
'assets/image.jpg',
width: double.infinity,
height: 196.0,
),
),
Positioned(
top: 136.0,
child: SizedBox(
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height,
child: Column(
mainAxisSize: MainAxisSize.min,
children: List.generate(
2,
(index) => Container(
height: 100,
width: double.infinity,
color: index % 2 == 0
? Colors.amberAccent
: Colors.cyanAccent,
), // some content inside the container
// some content inside the container
),
),
),
),
],
),
),
),
),
);
}
I have a SingleChildScrollView > Column > [A bunch of widgets, Text (really long text)]
I'm trying to make the Text go to the bottom of the screen so I tried 2 things and they both gave me errors
I tried adding a Spacer before the Text, but I got a RenderFlex error. I then tried wrapping all the widgets in a second column and leaving the Text widget in the 1st/original column. I also got an error with that.
How can I make the Text Widget go all the way to the bottom of the screen?
In SingleChildScrollView you can't use Spacer or Expanded widget. You should give height to your widget. I offer you try Stack widget like code below:
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: Stack(
children: [
SingleChildScrollView(
child: Column(
children: [
Container(
height: 100,
margin: EdgeInsets.all(10),
color: Colors.amber,
),
Container(
height: 100,
margin: EdgeInsets.all(10),
color: Colors.amber,
),
Container(
height: 100,
margin: EdgeInsets.all(10),
color: Colors.amber,
),
Container(
height: 100,
margin: EdgeInsets.all(10),
color: Colors.amber,
),
],
),
),
Align(
alignment: Alignment.bottomCenter,
child: Text('test'),
)
],
),
));
}
I'm trying to do my first flutter web page.
I want make navigation app bar on the top and scrollable area with pictures and text below.
And I have a problem with renering my page. Body of my page is not scrolling and it overflows at the bottom. What I'm doing wrong?
Here is my sample code:
#override
Widget build(BuildContext context) {
return Column(
children: [
TopBar(),
SingleChildScrollView(
child: Column(
children: [
Container(
height: 300,
color: Colors.red,
),
Container(
height: 300,
color: Colors.green,
),
Container(
height: 300,
color: Colors.black,
)
],
),
)
],
);
}
}
You can combine Column and ListView like:
#override
Widget build(BuildContext context) {
return Column(
children: [
AppBar(),
Expanded(
child: ListView(
children: [
Container(
height: 300,
color: Colors.red,
),
Container(
height: 300,
color: Colors.green,
),
Container(
height: 300,
color: Colors.black,
)
],
),
),
],
);
}
I have a listview which is equally divided into two parts(act as a background) How can i put a view above it( 100*100 w*h )?(This box should center align & top of root)
here is my tried code -
#override
Widget build(BuildContext context) {
return Scaffold(
body: ListView(
children: <Widget>[
Container(
width: ((context.findRenderObject() as RenderBox).size.width),
height: ((context.findRenderObject() as RenderBox).size.height)/2,
color: darkGreen,
),
// SizedBox(width: 10,),
Container(
width: ((context.findRenderObject() as RenderBox).size.width),
height: ((context.findRenderObject() as RenderBox).size.height)/2,
color: Colors.grey,
),
],
),
);
}
}
First of all, you don't need this line:
((context.findRenderObject() as RenderBox).size.width)
you can replace it with:
double.infinity
and it will take the maximum width the parent Widget can allow.
as for your question, you can wrap your ListView in a Stack:
Container(
width: double.infinity,
height: double.infinity,
child: Stack(
children: <Widget>[
ListView(
children: <Widget>[
Container(
width: double.infinity,
height:
((context.findRenderObject() as RenderBox).size.height) / 2,
color: darkGreen,
),
// SizedBox(width: 10,),
Container(
width: double.infinity,
height:
((context.findRenderObject() as RenderBox).size.height) / 2,
color: Colors.grey,
),
],
),
//place your desired widget here
],
),
),
