I am trying to put a text or container behind bottom Navigation Bar like pinterest bottom navigation
Container behind bottom navigation bar
#override
Widget build(BuildContext context) {
return Scaffold(
extendBody: true,
backgroundColor: Colors.red,
body: SafeArea(
child: Container(
height: 1000,
width: 200,
color: Colors.blue,
),
),
Add this to your Scaffold:
extendBody: true,

I need help. At the moment I'm trying to implement a background on my login page.
My problem is that I use a custom shape painter which shows my background.
To make my login page more dynamic I have added a function resizeToAvoidBottomInset: true, to move the textfield over the keyboard.
But now I have the problem that my background will be smaller if I click on my text field.
Here is my login page:
My code:
class _DebugPage extends State<DebugPage> {
#override
Widget build(BuildContext context) {
return Scaffold(
resizeToAvoidBottomInset: true,
appBar: customSubAppBar('Debug', context),
body: Stack(
children: [
//my custom shape painter
Expanded(
child: CustomeShapePainer(),
),
//my custom widgets
_body(context),
],
),
);
}
}
Is there a way to set the background on fix size?
I think you can try set widget CustomeShapePainer wrap Widget Stack. I don't remember exactly but in some projects I did
child: SingleChildScrollView(
child: Container(
color: AppConstants.bgColor,
height: MediaQuery.of(context).size.height,
width: MediaQuery.of(context).size.width,
child: CustomPaint(
painter: CurvePainter(),
child: Stack
Does anyone have any idea whether or not I can include a progress bar within an app bar? See screenshot of what I am trying to achieve. I am trying to reuse code and if I can create an App Bar with a Progress Indicator and then the same without. This will enable the users to complete this screen on signup and then EDIT this screen without the progress bar once they have an account. Is this even possible?
Your best option here is to use the 'bottom' property of the appBar widget it would look something like this
class HomeScreen extends StatelessWidget {
// this is to hide the progress inidecator once the account is created
bool isSignUpComplete = false;
#override
Widget build(BuildContext context) {
// this is to retrieve the device screen size
final Size size = MediaQuery.of(context).size;
return Scaffold(
appBar: AppBar(
bottom: !isSignUpComplete ? PreferredSize(
child: LinearProgressIndicator(
backgroundColor: Colors.red,
),
preferredSize: Size(size.width, 0),
) : null,
),
);
}
}
if you want to make a progress indicator in the app bar you can use the progress indicator in the title of the app bar but :
if you want to make it such as the image I will tell you how you can make a custom app bar below the progress indicator like this
class Myapplication extends StatelessWidget {
#override
Widget build(BuildContext context) {
Size size = MediaQuery.of(context).size;
return Scaffold(
body: SafeArea(
child: Column(
children: [
LinearProgressIndicator(),
Row(
children: [
Icon(Icons.arrow_back_outlined, color: Colors.black),
],
),
],
),
),
);
}
}
I solved this by putting the progress bar in the body, extended the body behind the app bar and then made the app bar transparent.
class SignUpForm extends StatelessWidget {
double progress = 0.22;
#override
Widget build(BuildContext context) => Scaffold(
backgroundColor: Colors.white,
extendBodyBehindAppBar: true,
appBar: BasicFormAppBar(),
body: Column(
children: [
SizedBox(height: 45),
Container(
child: LinearProgressIndicator(
value: progress,
valueColor: AlwaysStoppedAnimation(Colors.Blue),
backgroundColor: Colors.Grey,
),
), //column & scaffold are not closed in this snippet
How to create vertical tab navigation for dashboard in flutter web and whats it the best way?
You can you a NavigationRail to get this look. It was added to flutter this year. It works almost like the bottom tab bar.
I believe you want something similiar to what is shown in the screenshot right?
If so, I would recommend you to use the Scaffold Widget and making use of the attributes appBar and drawer.
For further information about the Scaffold Widget please check this link.
Here a simple example:
In your main Widget modify the build function like this.
#override
Widget build(BuildContext context) {
GlobalKey<ScaffoldState> key = GlobalKey();
return Scaffold(
key: key,
drawer: Padding(
padding: const EdgeInsets.fromLTRB(0, 70, 0, 0),
child: Container(
color: Colors.red,
width: 300,
child: Column(children: [Text("1"), Text("2"), Text("3")])),
),
appBar: AppBar(
toolbarHeight: 70,
elevation: 5,
centerTitle: true,
backgroundColor: Colors.black,
leading: RawMaterialButton(
child: Icon(Icons.menu),
onPressed: () => key.currentState.openDrawer(),
),
title: Container(child: Text("Title Widget")),
),
body: Container(
child: Text("Main Widget"),
));
}
The result would look like this:
I’m working on the concept that you can see on the screenshot below:
design concept
Note: the arrows are not the part of the UI, but were added to demonstrate the draggable functionality.
The screen has a SliverAppBar that displays location title, Sliver body that contains location description, and has a DraggableScrollableSheet (or a similar alternative).
When the location description is scrolled up, the title collapses.
When the DraggableScrollableSheet is scrolled up it expands to the full height of the screen.
I tried many times to put it together, but something is always off.
My last attempt was to add DraggableScrollableSheet as a ‘bottom sheet:’ in Scaffold. Since I have a BottomAppBar, it breaks the UI, and looks the following way:
current UI behavior
Scaffold
#override
Widget build(BuildContext context) {
return Scaffold(
body: body,
extendBody: true,
appBar: appBar,
bottomSheet: hasBottomSheet
? DraggableScrollableSheet(
builder:
(BuildContext context, ScrollController scrollController) {
return Container(
color: Colors.blue[100],
child: ListView.builder(
controller: scrollController,
itemCount: 25,
itemBuilder: (BuildContext context, int index) {
return ListTile(title: Text('Item $index'));
},
),
);
},
)
: null,
backgroundColor: Colors.white,
floatingActionButtonLocation: fab_position,
floatingActionButton: hasActionButton ? ScannerFAB() : null,
bottomNavigationBar: AppBarsNav(hasNavButtons: hasNavButtons));
}
Scaffold body
class LocationPage extends StatelessWidget {
#override
Widget build(BuildContext context) {
return ScaffoldWithNav(
hasBottomSheet: true,
body: CustomScrollView(
slivers: <Widget>[
SliverBar(
title: "Location",
hasBackground: true,
backgroundImagePath: 'assets/testImage.jpg'),
SliverToBoxAdapter(
child: Text("very long text "),
),
SliverPadding(
padding: EdgeInsets.only(bottom: 70),
),
],
),
);
}
}
BottomAppBar FAB
class ScannerFAB extends StatelessWidget {
#override
Widget build(BuildContext context) {
return FloatingActionButton(
child: WebsafeSvg.asset('assets/qr-code.svg',
color: Colors.white, height: 24, width: 24),
);
}
}
The FAB jumps, the content is hidden.
When I set a fixed-sized container, the content comes back, but the FAB is still living its own life:)
current UI behavior2
If anyone has any idea how to solve this issue/those issues please share, I’ll be very grateful!
You can try to add another Scaffold on current body and put the DraggableScrollableSheet inside it. Then the DraggableScrollableSheet won't affect the FAB outside.
#override
Widget build(BuildContext context) {
return Scaffold(
body: Scaffold(
body: body,
bottomSheet: ... // move DraggableScrollableSheet to here
),
...
floatingActionButton: ... // keep FAB here
...
)
You can use Stack into Body, for example:
#override
Widget build(BuildContext context) {
return Scaffold(
body: Stack(
children. [
SingleChildScrollView(),
DraggableScrollableSheet(),
]
),
...
floatingActionButton: ... // keep FAB here
...
)
My app doesn't use AppBar, and the content is overlapping with status bar when scrolled. I tried using AnnotatedRegion<SystemUiOverlayStyle>, however it doesn't change anything.
Overlapped
My best try is using SafeArea, however it turned Status Bar to grey.
Grey Safe Area
Is there a way to maintain the automatic color of status bar, without it overlapping with the content?
Additional Note:
Flutter 1.17.5
My Tree
SafeArea
|_ SingleChildScrollView
|_ Column
|_ Container
|_ Container
|_ Container
EDIT: I just realized the automatic color (status bar follow the first container's color) was because it was transparent. I was thinking of making it solid on runtime, and read it from the first colored widget.
import 'package:flutter/services.dart';
#override
Widget build(BuildContext context){
return AnnotatedRegion<SystemUiOverlayStyle>(
value: SystemUiOverlayStyle(
statusBarColor: Colors.blue, //or the color you prefer
),
child: SafeArea(child: Scaffold(...)),
);
}
You need to wrap your SafeArea widget with Container widget to change the color of the SafeArea widget
SAMPLE CODE
Scaffold(
backgroundColor: Colors.white,
body: Container(
color: Colors.red, /* Set your status bar color here */
child: SafeArea(
child: Container(
/* Add your Widget here */
)),
),
);
Another way You can use AppBar
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
elevation: 0.0,
backgroundColor: Colors.red,
),
body: Container(
child: //widget
)
);
}
