How to put raw data in a http get request in Flutter(Dart)?

I'm trying to execute the following curl in dart but I can't find a way to achieve that:

curl --location --request GET 'https://someurl.com/query' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer xxxx' \
--data-raw '{
    "query":"test_value",
    "size":10
}'

The only way I've found to achieve this is to use POST and put the raw data inside the body but I was wondering if there is a real way to achieve that since the POST request with a body seems to be about 220ms slower than the GET one(I know that they should be almost equal, it may be something from the server when recieving the request).

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

// Define the raw data to be sent in the request
String rawData = '{ "key": "value" }';

// Send the GET request with the raw data as the body
http.Response response = await http.get(
  'https://example.com/endpoint',
  headers: {'Content-Type': 'application/json'},
  body: rawData,
);

// Check the status code of the response to see if the request was successful
if (response.statusCode == 200) {
  // The request was successful, process the response
} else {
  // The request was not successful, handle the error
}

The default get() method of the http package doesn't allow you to add data since that isn't a common thing to do. You can get around this by using the Request object directly for more fine-grained control, as stated in the docs:

Request req = Request('GET', Uri.parse('https://someurl.com/query'))
  ..body = json.encode(data)
  ..headers.addAll({
    "Content-type": "application/json",
    "Authorization": "Bearer xxxx"
  });

var response await req.send();
if (response.statusCode == 200) {
    // do something with valid response
}

I'd look at getting the POST variant working properly, since a GET method semantically shouldn't do anything with the provided body. But that's a different discussion of course.
