Hi I've been building this app and I came across a problem that I dont know how to solve. I want to have a Row of Card Widgets, that all display some info I provided beforehand. This is basically how I wanted to do it:
``
import 'package:flutter/material.dart';
class MyClass {
// here I am generating fake movies but you should use the data that you already have
List<Map<String, dynamic>> movies = List.generate(
15,
(index) => {
'title': 'fake title $index',
'actors': ['fake actor $index'],
'bannerPath': 'some/fake/path/$index',
'description': 'some fake description $index',
});
List<MovieModel> get models =>
movies.map((movie) => MovieModel.fromJson(movie)).toList();
List<Widget> get widgets =>
models.map((model) => MovieWidget(model: model)).toList();
}
class MovieModel {
MovieModel({
required this.title,
required this.actors,
required this.bannerPath,
required this.description,
});
factory MovieModel.fromJson(Map<String, dynamic> json) {
return MovieModel(
title: json['title'],
actors: json['actors'],
bannerPath: json['bannerPath'],
description: json['description'],
);
}
String title;
String bannerPath;
String description;
List<String> actors;
}
class MovieWidget extends StatelessWidget {
const MovieWidget(
{required this.model}); // if you decide to not make a model class, you would pass each value individually
final MovieModel model;
@override
Widget build(BuildContext context) {
// obviously this can be any widget you want
return SingleChildScrollView(
child: Card(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(25.0),
),
elevation: 10.0,
margin: const EdgeInsets.all(10.0),
child: Column(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
height: 200.0,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10.0),
image: DecorationImage(

The output on the emulator looks like this: https://drive.google.com/file/d/1nDah5cqgBLNBS69n4sJ5Xi8rtEmgWSOJ/view?usp=sharing
- How do I get the text to appear in several lines (descriptiontext) not in one?
- Why isn't my AssetImage showing up?
Thanks for the help in advance :)
CodePudding user response：
You can do so by restricting the Card width by SizedBox or Container and then using the maxLines and overflow as you had used.
See the changes below in your MovieWidget
@override
Widget build(BuildContext context) {
return SizedBox(
width: 300,
height: 305,
child: Card(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(25.0),
),
elevation: 10.0,
margin: const EdgeInsets.all(10.0),
child: Column(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
height: 200.0,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10.0),
image: DecorationImage(
image: AssetImage(model.bannerPath), fit: BoxFit.cover),
),
),
Padding(
padding: const EdgeInsets.all(10.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
model.title,
maxLines: 1,
overflow: TextOverflow.ellipsis,
style: const TextStyle(
color: Colors.redAccent,
fontWeight: FontWeight.w800),
),
Text(
model.description,
maxLines: 3,
overflow: TextOverflow.ellipsis,
style: const TextStyle(fontWeight: FontWeight.w500),
),
]),
),
],
)));
}
