Flutter retrieve data from Json url

To retrieve data from a JSON URL in Flutter, you can use the http package. Here's an example of how you can do this:

First, make sure to add the http package to your pubspec.yaml file:

  http: ^0.13.4

Then, import the package in your Dart file:

import 'package:http/http.dart' as http;
import 'dart:convert';

Next, you can make an HTTP GET request to the JSON URL and parse the response:

Future<void> fetchData() async {
  var url = Uri.parse('https://example.com/data.json');
  var response = await http.get(url);

  if (response.statusCode == 200) {
    var data = jsonDecode(response.body);
    // Process the retrieved data here
  } else {
    print('Failed to fetch data: ${response.statusCode}');

In the above example, replace 'https://example.com/data.json' with the actual URL of your JSON data.

Inside the if (response.statusCode == 200) block, you can access the parsed JSON data using the data variable. You can then process the retrieved data according to your needs.

Remember to handle any potential errors by checking the response status code, as shown in the above example.

That's it! You can call the fetchData function to retrieve and process the JSON data from the specified URL.
