json in listview flutter

To display JSON data in a ListView in Flutter, you can follow these steps:

  1. First, ensure that you have added the http package as a dependency in your pubspec.yaml file.

  2. In your Flutter widget, import the necessary packages:

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
  1. Create a model class to represent your JSON data. This class should have properties that match the JSON fields. For example, if your JSON has a "name" field, your model class should have a corresponding "name" property:
class MyData {
  final String name;
  // Add other properties as needed

  MyData({required this.name});

  factory MyData.fromJson(Map<String, dynamic> json) {
    return MyData(name: json['name']);
  1. Inside your Flutter widget, define a function to fetch the JSON data from an API endpoint using the http package:
Future<List<MyData>> fetchData() async {
  final response = await http.get(Uri.parse('Your API endpoint URL'));

  if (response.statusCode == 200) {
    List<dynamic> jsonData = jsonDecode(response.body);
    List<MyData> data = jsonData.map((json) => MyData.fromJson(json)).toList();

    return data;
  } else {
    throw Exception('Failed to fetch data');
  1. In your widget's initState method, call the fetchData function and set the data to a state variable:
List<MyData> _data = [];

void initState() {
  fetchData().then((data) {
    setState(() {
      _data = data;
  1. Finally, use the ListView.builder widget to display the data in your widget's build method:
  itemCount: _data.length,
  itemBuilder: (BuildContext context, int index) {
    return ListTile(
      title: Text(_data[index].name),
      // Display other properties as needed

This code fetches the JSON data from the API endpoint, converts it into a list of MyData objects using the model class, and then displays it in a ListView using the ListView.builder widget. You can customize the UI as needed to display the other properties of your JSON data.
