How can I fix the RenderFlex overflowed pixel in my card Flutter? I cant seem to find a tutorial regarding this kind of problem. All of the tutorials in StackOverflow teach you to use the listview and SingleChildScrollView but that is not the case for me. The error shows in the card itself and I don't want the card to be using a singlechildscrollview.
I already tried fixing it by lowering the height and width but I will still need a proper tutorial that can help me fix this kind of issues.
This is the card.dart for the application
import 'package:flutter/material.dart';
class ListViewCard extends StatelessWidget {
final String title;
final void Function()? onTap;
final String imageOfPlant; //Change to String
const ListViewCard({
super.key,
required this.title,
required this.onTap,
required this.imageOfPlant,
});
@override
Widget build(BuildContext context) {
return Card(
color: const Color.fromARGB(255, 75, 175, 78),
elevation: 1,
margin: const EdgeInsets.all(8),
semanticContainer: true,
clipBehavior: Clip.antiAliasWithSaveLayer,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10.0),
),
child: InkWell(
splashColor: Colors.lightGreenAccent.withAlpha(30),
onTap: onTap,
//sizedBox of the card
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
//image of the card
Image.asset(
imageOfPlant,
height: 200,
width: 150,
fit: BoxFit.cover,
),
SizedBox(
height: 50,
width: 150,
child: Center(
child: Text(
title,
textAlign: TextAlign.center,
style: const TextStyle(
fontSize: 19,
fontFamily: 'RobotoMedium',
color: Color(0xffeeeeee)), // textstyle
),
),
), //text //SizedBox
], // <widget>[]
), // column
), //inkwell
); // card
}
}
This is the home.dart where the card will be called.
import 'package:flutter/material.dart';
import 'package:picleaf/nav_pages/plant.dart';
import '../widgets/card.dart';
class homePage extends StatefulWidget {
const homePage({super.key});
@override
State<homePage> createState() => _HomePageState();
}
List<String> plants = [
"Bell Pepper",
"Cassava",
"Grape",
"Potato",
"Strawberry",
"Tomato",
];
class CustomSearchDelegate extends SearchDelegate {
// Demo list to show querying
CustomSearchDelegate({String hinttext = "Search plants here"})
: super(searchFieldLabel: hinttext);
// first overwrite to
// clear the search text
@override
List<Widget>? buildActions(BuildContext context) {
return [
IconButton(
onPressed: () {
query = '';
},
icon: const Icon(Icons.clear),
),
];
}
// second overwrite to pop out of search menu
@override
Widget? buildLeading(BuildContext context) {
return IconButton(
onPressed: () {
close(context, null);
},
icon: const Icon(Icons.arrow_back),
);
}
// third overwrite to show query result
@override
Widget buildResults(BuildContext context) {
List<String> matchQuery = [];
for (var fruit in plants) {
if (fruit.toLowerCase().contains(query.toLowerCase())) {
matchQuery.add(fruit);
}
}
return ListView.builder(
itemCount: matchQuery.length,
itemBuilder: (context, index) {
var result = matchQuery[index];
return ListTile(
title: Text(
result,
style: const TextStyle(fontFamily: 'RobotoMedium'),

);
},
);
}
// last overwrite to show the
// querying process at the runtime
@override

List<String> matchQuery = [];
for (var fruit in plants) {
if (fruit.toLowerCase().contains(query.toLowerCase())) {
matchQuery.add(fruit);
}
}

itemBuilder: (context, index) {

CodePudding user response：
Your gridView's Item give you a specific size but you are setting more than that for your container and text, I suggest you try this:
child: Stack(
children: <Widget>[
//image of the card
Image.asset(
imageOfPlant,
height: double.infinity,
width: 150,
fit: BoxFit.cover,
),
Positioned(
bottom: 0,
left: 0,
right: 0,
child: SizedBox(
height: 50,
width: 150,
child: Center(
child: Text(
title,
textAlign: TextAlign.center,
style: const TextStyle(
fontSize: 19,
fontFamily: 'RobotoMedium',
color: Color(0xffeeeeee)), // textstyle
),
),
),
), //text //SizedBox
], // <widget>[]
),
and If you want to change item's AspectRatio you can do this:
GridView.count(
physics: const ScrollPhysics(),
shrinkWrap: true,
crossAxisSpacing: 20,
mainAxisSpacing: 20,
crossAxisCount: 2,
childAspectRatio: 2 / 3, <--- add this
children: <Widget>[
...
]
