I am using flutter 3.0.0
In my application I am displaying a native video using platform view.
The video is displaying but it is always displaying on upper left corner and it covers other
widgets even they are in a stack.
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
// Here we take the value from the MyHomePage object that was created by
// the App.build method, and use it to set our appbar title.
title: Text(widget.title),
),
body: Stack(
children: [
Center(
child: ConstrainedBox(
constraints:
const BoxConstraints.expand(height: 200, width: 200),
// Center is a layout widget. It takes a single child and positions it
// in the middle of the parent.
child:
const AndroidView(viewType: 'remote-video'),
),
),
Row(
children: [
Padding(
padding: const EdgeInsets.all(8.0),
child: ElevatedButton(
onPressed: () {
MethodChannels.coreMethodChannel
.invokeMethod("load");
},
child: const Text('Invoke'),
),
),
],
),
],
),
);
}
This is how it looks when I run the code
As you can see it is displaying over everything.
Can you provide some advice on how to fix this?
As of 31/07/2022 this seems to be a bug in flutter >= 3.0.0. Following the solution in this question Flutter AndroidView Widget I downgraded to 2.10.5 and then it worked as expected. Hopefully the flutter team will resolve it shortly.
I want to remove the strange padding on top of the status bar. I am simply using an image and want to put that image on top of the screen that is behind the status bar. So that the status bar icons should be overlayed on the image.
Simply using Scaffold as a parent widget and then simple an Image. Screen shot is here!
The icons are not properly overlapping the image, and there is a white padding on top head!
I am using an Android Emulator right now, can somebody please figure out what I am missing.
class PreSignInScreen extends StatelessWidget {
final PreSignInController controller = Get.put(PreSignInController());
#override
Widget build(BuildContext context) {
return Scaffold(
body: SingleChildScrollView(
child: Column(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
const SizedBox(
height: 10,
),
getRedCarBox(context),
]
);
)
}
Thanks & Advance
Try below code, I have tried
- Scaffold
- Column
- Container
- Image
Your Widget:
Scaffold(
body: Column(
children: [
Container(
width: double.infinity,
height: 300,
decoration: BoxDecoration(
image: DecorationImage(
fit: BoxFit.fill,
image: NetworkImage(
'https://cdn.pixabay.com/photo/2022/03/27/11/23/cat-7094808__340.jpg',
),
),
),
),
//Add your other widgets here
],
),
),
Or Using SafeArea, top property false
SafeArea(
top: false,
child: Container(),
),
Result Screen->
Try this:
#override
Widget build(BuildContext context) {
return WillPopScope(
onWillPop: () async {
return false;
},
child: Scaffold(
body: SafeArea(
top: false,
bottom: false,
child: _buildBody(),
),
),
);
}
Scaffold(
body: SafeArea(
top: false,
bottom: false,
child: _yourBody(),
),
Why to use SafeArea :
SafeArea class Null safety. A widget that insets its child by sufficient padding to avoid intrusions by the operating system. For example, this will indent the child by enough to avoid the status bar at the top of the screen.
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
I want to reuse mobile app code for flutter web. I already coded with AppBar() and body widgets in scaffold in all screens. Now i am taking 400 width and center for web, it is good except appbar.
Scaffold(
appBar: this.getAppBarWidget(),
body: Center(
child: Container(
width: kIsWeb ? 400.0 : MediaQuery.of(context).size.width,
child: this.getBodyWidget(),
),
))
Above code is perfectly working for all screens of mobile and web except appbar in web.
How do i change width of appbar to fit width 400 ?
If i use Size.fromWidth(400) getting error.
Below code is working for mobile and web.
Scaffold(
body: Center(
child: Container(
width: kIsWeb ? 400.0 : MediaQuery.of(context).size.width,
child: Column(
children: [
this.getCustomAppbarWidget(),
this.getBodyWidget(),
],
),
),
))
Please suggest me.
The size this widget would prefer if it were otherwise unconstrained.
In many cases it's only necessary to define one preferred dimension. For example the [Scaffold] only depends on its app bar's preferred height. In that case implementations of this method can just return new Size.fromHeight(myAppBarHeight).
But we can provide customAppBar like
class MyAppBar extends StatelessWidget implements PreferredSizeWidget {
const MyAppBar({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Align(
alignment: Alignment.centerLeft,
child: Container(
alignment: Alignment.center,
color: Colors.pink,
// we can set width here with conditions
width: 200,
height: kToolbarHeight,
child: Text("MY AppBar"),
),
);
}
///width doesnt matter
#override
Size get preferredSize => Size(200, kToolbarHeight);
}
and use
Scaffold(
extendBodyBehindAppBar: true,
appBar: MyAppBar(),
body: ......
if it cover the 1st item of body, and in this case use SizedBox(height: kToolbarHeight) to handle the situation if needed.
Result
As i know, width did not allow in AppBar. Only height is allowed in AppBar
toolbarHeight: 60,
But if you want to apply manually width in your AppBar you can wrap your AppBar in Padding component
return Scaffold(
body: Column(
children: [
Container(
width: kIsWeb? 400 : double.maxFinite,
child: AppBar(
title: Text('hello'),
),
),
Expanded(child: HomePageOne()), // this expanded is you page body
],
),
);
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:
