How should I treat gray-out area on pixcel device？

I'm sorry that I have never see or used an actual device with android OS such as Google pixcel, but I found that gray-out area on top of screen like screen shot below.
*This is "Pixcel 4 API 30 mobile emulator" called from vsCode.
And I found this kind of dead area on Pixcel 5 emulator as well, but am not sure that this is somthing in common for all android OS.
Finally, I'd like to ask that if I should avoid something to display here or this is only emulator matters and do not have to care about this ?
In case that I have to care this area with developing by flutter, should I intentionally separate code or design between these kind of device and the others, as I'm usually using Iphone emulator and actual machine but have never seen this area and beleive I need not to care this kind of area and adopting top-margin for this problem.
Thanks for your helpful comment.
Code Added:
class holder extends ConsumerWidget {
#override
Widget build(BuildContext context, WidgetRef ref) {
ref.watch(_modalProvider );
return Scaffold(
body: Column(
children: [
Container(
margin: const EdgeInsets.only(bottom: 10),
// flex: 1,
child: Container(
margin: EdgeInsets.only(top: 40),//should I do this to avoid this area?
width: double.infinity,
height: 40,
// color: Colors.grey,
alignment: Alignment.topLeft,
child: Image.asset('images/flutter.png'),
),
),
Flexible(
child: ListView(
scrollDirection: Axis.vertical,
shrinkWrap: true,
children: [
Folders(
name: "list",
subTitle: null,
),
],
)
),
],
),
floatingActionButtonLocation: FloatingActionButtonLocation.endTop,
floatingActionButton: Container(
width: 50.0,
child: FloatingActionButton(
backgroundColor: Colors.white,
child: const Icon(
Icons.search_sharp,
color: MyStyle.mainColor,
),
onPressed: () {
ref.read(_modalProvider.notifier).update((state){
showTopModalSheet<String?>(context, DumyModal());
});
},
),
),
);
}
}

That area will be also visible in real devices so you should take that area into consideration. But Scaffold widget will start the rendering from below that point so you don't have to think about it.
İf you want to change color of that area, you can
Container(
decoration: BoxDecoration(color: Color.white),
child: SafeArea(
Scaffold:...
)
)
It also effects IOS and Android devices differently, I believe that is why it is only visible in some devices

How to solve ElevatedButton error in flutter

I am new to flutter and I am developing an app in Flutter. While I am doing this, I try to add ElevatedButton which is the latest version of RaisedButton, and its return error and I am also not sure why. I will insert the error code image and would be grateful if someone tells me what is the reason for the error and how to solve it. Thank you

You need to add a child widget (it is required in addition to onPressed function). Here is a sample code for Elevated Button. You can adjust it based on your needs:
ElevatedButton(
style: ElevatedButton.styleFrom(
onPrimary: Colors.white,
primary: Color(0xffccbbd7),
minimumSize: const Size(330,70),
shape: const RoundedRectangleBorder(
borderRadius: BorderRadius.all(
Radius.circular(5),
),
),
),
onPressed: () {},
child: const Text('click'),
),

You Forgot the child Widget inside ElevatedButton, in this button onPressed and child widgets are required
Refer ElevatedButton
Try below code
ElevatedButton(
onPressed: () {
// write your onPressed function here
print('Button Pressed');
},
child: const Text('Press Me'),
),
Your result screen->

Well, elevated button should have child inside. Can be text, icon or image
ElevatedButton(
onPressed: () {
print('Tombol baru saja ditekan!');
},
child: const Text('Hit me!'),
),

Is there a widget in flutter that allows you to create such a view?

I need to implement such a widget in Flutter. Full version of the page, where this widget is going to be used is here Maybe you know build-in widgets, which could help me. But if there are none, what is the best way to implement this widget?

You can use a ListTile
ListTile(
leading: const Text("Lbikgabsb"),
trailing: Column(
children: [
const Text("900 P"),
const Text("2"), // add your decoration to the background
),
],
),
),
Alternatively you can use:
SizedBox(
height: your_height,
width:double.infinity,
child: Row(
children:[
Text("Lbikgabsb"),
Column(
children: [
const Text("900 P"),
const Text("2"), // add your decoration to the background
],
),
),
You can choose whichever approach works best for your app

FLUTTER: How to use text widget inside a string

I have a list of text widgets like this:
List<Widgets> widgets = [
Text('Theo', style: TextStyle(color: Colors.green)),
Text('Luca', style: TextStyle(color: Colors.blue))
]
and I have list of Strings like this:
'My name is #name',
'#name how old are you ?'
I want to replace the #name by a text widget in the list to print the right name with the right color.
Do you know a way to do it ?

you probably looking for rich text widget check this
RichText

It's not possible in Text Widget, use RichText Widget which takes TextSpan as children.
Change Text to Text Span
List<Widgets> widgets = [
TextSpan(text: 'Theo', style: TextStyle(color: Colors.green)),
TextSpan(text: 'Luca', style: TextStyle(color: Colors.blue))
]
Each line is a RichText. RichText takes TextSpan as children where the text and the corresponding style has to be specified.
widgets.map((textSpan) {
return Column(
children: [
RichText(
text: TextSpan(
text: 'My name is ',
style: DefaultTextStyle.of(context).style,
children: <TextSpan>[
textSpan // Name with color will appear here
],
),
RichText(
children: <TextSpan>[
textSpan // Name with color will appear here
TextSpan (
text: 'How old are you? ',
style: DefaultTextStyle.of(context).style,
),
],
),
],
)
}
Alternatively this can replicated by using Row and Text widgets but then it won't be a single line.

How can i load an image in between a text in Flutter

I need to display content containing text and images from an API on my android app, when I save it in a variable of type String, the texts get displayed but the images shows as url. How do I load the get the links to load in between the texts?

I needed to insert an Image inline with a sentence of texts.
So for that I used this:
final String paragraph1 =
'Advanciti App is an app where you can study and make friends with people living near your home. Advanciti is an Edtech Startup based out of Pune, Maharashtra, India.\n';
RichText(
text: TextSpan(
children: [
TextSpan(text: "The "),
WidgetSpan(child: Container(width: 20.0, child: Image.asset('assets/app_icon.png', scale: 1))),
TextSpan(text: paragraph1),
],
),
),

if you want to show images you need to convert your data to HTML or Markdown. in MarkDown and HTML, you can show much more then the image. these are packages for HTML and MarkDown:
flutter_html
flutter_markdown

You can use the following to place an image between two texts vertically:
Column(
children: <Widget>[
Text("Hello"),
Image.network(
'REPLACE HERE WITH YOUR IMG URL'),
Text("World")
],
),
or you can use this to place an image between two texts horizontally:
Row(
children: <Widget>[
Text("Hello"),
Image.network(
'REPLACE HERE WITH YOUR IMG URL'),
Text("World")
],
),
