I'm currently building products from my store in my products screen, What I'm attempting to do is, create a GridView and a card for each product. I'm having problem with the overflow from the image.
What I want to look like:
How it is going:
My code for the card:
import 'package:flutter/material.dart';
import 'package:google_fonts/google_fonts.dart';
import 'package:loja_virtual_nnananene/helpers/color_select.dart';
import 'package:loja_virtual_nnananene/models/product.dart';
class ProductListTile extends StatelessWidget {
const ProductListTile(this.product);
final Product product;
#override
Widget build(BuildContext context) {
return GestureDetector(
onTap: () {
Navigator.of(context).pushNamed('/product', arguments: product);
},
child: Card(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Stack(
alignment: Alignment.center,
children: [Image.network(product.images!.first)],
),
Text(
product.name,
style: GoogleFonts.firaCode(
textStyle:
TextStyle(fontSize: 14, fontWeight: FontWeight.bold)),
),
Text('R\$ ${product.basePrice.toStringAsFixed(2)}',
style: GoogleFonts.firaCode(
textStyle: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w800,
color: ColorSelect.cprice)))
],
),
));
}
}
Try to add your Card Widget inside SingleChildScrollView() Widget :
SingleChildScrollView(
child:Card(),
),
There is no need Stack widget in your code. Try this:
If you want u can remove ConstrainedBox, but image size will be different according to its size.
import 'package:flutter/material.dart';
import 'package:google_fonts/google_fonts.dart';
import 'package:loja_virtual_nnananene/helpers/color_select.dart';
import 'package:loja_virtual_nnananene/models/product.dart';
class ProductListTile extends StatelessWidget {
const ProductListTile(this.product);
final Product product;
#override
Widget build(BuildContext context) {
return GestureDetector(
onTap: () {
Navigator.of(context).pushNamed('/product', arguments: product);
},
child: Card(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
ConstrainedBox(
constraints: const BoxConstraints(
minHeight: 50.0,
maxHeight:300.0
),
child: Image.network(product.images!.first),
),
Text(
product.name,
style: GoogleFonts.firaCode(
textStyle:
TextStyle(fontSize: 14, fontWeight: FontWeight.bold)),
),
Text('R\$ ${product.basePrice.toStringAsFixed(2)}',
style: GoogleFonts.firaCode(
textStyle: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w800,
color: ColorSelect.cprice)))
],
),
));
}
}
Are you using SliverGridDelegateWithFixedCrossAxisCount? If yes, it has a property aspectRatio which is default to 1.0 (height will be same as width). Try to make it 0.7 or something and your error will be gone in that case.
You can achieve the first image this way
Container(
decoration: Boxdecoration(
color: Colors.white,
borderRadius: borderRadius.circular(8),
boxShasow: [
BoxShadow(
offset: Offset(10,17),
blurRadius:17,
spreadRadius: -23,
color: Colors.grey,),],),
child: Padding(
padding: const EdgeInset.all(10.0),
child: Column(
Image.network(
"your url",
width: width of choice,
height: height of choice,
),
Text(
"product name",
testAlign:TestAlign.left,
style:(your style),
),
Row(
children:<Widget>[
Text(
"product amount",
testAlign:TestAlign.left,
style:(your style),
),
Expanded(
child:Column(
crossAxisAlignment: CrossAxisAlignment.end,
children: <Widget>[
Icon(
Icons.heart_outlind,
color:Colors.blue,
size:24,
),
SizedBox(width:5),
],),),
],),),),

I'm trying to write a page to show the elements of a music album uploaded to Firestore, but when I navigate to another page using Navigator.pushNamed, passing the album name as an argument, I get an error:

Make sure you you register you the page that you want to navigate to in the material app routes https://docs.flutter.dev/development/ui/navigation#using-named-routes
I have created a list of the widgets using JSON data, I have five types of widgets, and each widget is added to the list depending on the JSON data, but the issue is with the widget includes a text field, All widget displays ok but once I click on the text field the keyboard appears and disappears immediately and gives this error "Exception caught by widgets library" => "Incorrect use of ParentDataWidget."
I try removing everything and adding just this text field widget in the list, but it still not working right. Please guide me on where am doing wrong.

TextFields usually try to expand to the available width. This can be problematic in a Column where usually only height is fixed and the Textfield tries to expand into infinity. You should try wrapping the TextField in a Widget that gives it a fixed width like a SizedBox.
I want to add image before the result. I added in pubspec.yaml
assets/images/ .
Where write Image.asset("assets/images/mark.png")?
Is there any way to do it?
result.dart
import 'package:flutter/material.dart';
class Results extends StatefulWidget {
final int total, correct, incorrect, notattempted;
Results({this.incorrect, this.total, this.correct, this.notattempted});
#override
_ResultsState createState() => _ResultsState();
}
class _ResultsState extends State<Results> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: Center(
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
Text("${widget.correct}/ ${widget.total}", style: TextStyle(fontSize: 25),),
SizedBox(height: 5,),
Container(
padding: EdgeInsets.symmetric(horizontal: 24),
child: Text(
"you answered ${widget.correct} answers correctly and ${widget.incorrect} answeres incorrectly",
textAlign: TextAlign.center,),
),
SizedBox(height: 24,),
GestureDetector(
onTap: (){
Navigator.pop(context);
},
child: Container(
padding: EdgeInsets.symmetric(horizontal: 24, vertical: 8),
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.circular(30)
),
child: Text("Go to home", style: TextStyle(color: Colors.white, fontSize: 19),),
),
)
],),
),
),
);
}
}
Is there any way to do it? In case you want to see the code please let me know I will update more.
I am not sure what do you mean by image before the result. Do you mean add the image as first item to be appear under column?
import 'package:flutter/material.dart';
class Results extends StatefulWidget {
final int total, correct, incorrect, notattempted;
Results({this.incorrect, this.total, this.correct, this.notattempted});
#override
_ResultsState createState() => _ResultsState();
}
class _ResultsState extends State<Results> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: Center(
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
Image.asset('assets/images/mark.png'),
Text("${widget.correct}/ ${widget.total}", style: TextStyle(fontSize: 25),),
SizedBox(height: 5,),
Container(
padding: EdgeInsets.symmetric(horizontal: 24),
child: Text(
"you answered ${widget.correct} answers correctly and ${widget.incorrect} answeres incorrectly",
textAlign: TextAlign.center,),
),
SizedBox(height: 24,),
GestureDetector(
onTap: (){
Navigator.pop(context);
},
child: Container(
padding: EdgeInsets.symmetric(horizontal: 24, vertical: 8),
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.circular(30)
),
child: Text("Go to home", style: TextStyle(color: Colors.white, fontSize: 19),),
),
)
],),
),
),
);
}
}
More details about the Asset image can found here.
Wrap the Results class with Column widget where you are using. And add image just before in Results class.

How do I resolve this? Thanks in advance!
You are right, Simulator is not a problem. The problem is in your code. You have correctly created the LoginPage. To correct the LoginForm widget, in your LoingFormState's build function replace:
body: Card(
// your usual code that you have above
)
with
return Card(
// your usual code that you have above
)
Also you have not used the LoginForm Widget in the LoginPage, and that is the reason the form is not visible. Simply, creating a widget doesn't include the widget on any screen, you have to use the widget.
You can do that by adding the widget inside the body section of LoginPageState's build function. To use the widget type
body: Stack(
children: <Widget>[
// your other widgets
LoginForm(),
]
)
like you do for any other widget.
This should solve your problem
