To fetch data from an API in a Flutter app, you can use the http package, which provides a simple and efficient way to make HTTP requests and receive HTTP responses.
Here is an example of how you might use the http package to fetch data from an API in a Flutter app:
import 'package:http/http.dart' as http;
// Make a GET request to the API
final response = await http.get('example.com/ap...
// Check the status code of the response
if (response.statusCode == 200) {
// If the request was successful, parse the JSON data
final data = json.decode(response.body);
// Use the data as needed
} else {
// If the request was unsuccessful, throw an error
throw Exception('Failed to fetch data');
}
In this example, the http.get function is used to make a GET request to the API, and the response object is used to hold the response from the server. The statusCode property of the response object is used to check whether the request was successful or not, and the body property is used to hold the data returned by the server.
You can also use the http package to make other types of HTTP requests, such as POST, PUT, and DELETE, by using the http.post, http.put, and http.delete functions, respectively.
