can we send raw json in get method in flutter

Yes, you can send raw JSON data in a GET method in Flutter. To do this, you need to convert the JSON data into a query parameter and append it to the URL. Here's an example of how you can achieve this:

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

final jsonData = {'key1': 'value1', 'key2': 'value2'};
final jsonString = jsonEncode(jsonData);
final url = Uri.parse('https://example.com/api?data=$jsonString');

http.get(url).then((response) {
  if (response.statusCode == 200) {
    // Process the response here
    print(response.body);
  } else {
    // Handle error cases
    print('Request failed with status: ${response.statusCode}');
  }
}).catchError((error) {
  // Handle any error that occurred during the request
  print(error);
});

In this example, we first encode the JSON data using jsonEncode from the dart:convert package. Then, we create a Uri object with the URL and append the JSON string as a query parameter called data. Finally, we use the http package to send the GET request to the specified URL.

Please note that sending raw JSON data in a GET request may not be the most secure or efficient way to transmit data. It is generally recommended to use POST requests for sending large or sensitive data.
