can we send raw json in get method in flutter

import 'package:http/http.dart' as http;
import 'dart:convert';
class API
{
//replace with your endpoint
static String BASE_URL = 'https://some-url/api/';

 static Future<List<ExampleData>> getRequest() async {
   
    Response res = await http.get(BASE_URL+'example');
    
      if (res.statusCode == 200) {
      List<dynamic> body = jsonDecode(res.body);
        
     // complete by parsing the json body return into ExampleData object and return
     //.................
      }
}

}
final queryParameters = {
  'name': 'Bob',
  'age': '87',
};
final uri = Uri.http('www.example.com', '/path', queryParameters);
final headers = {HttpHeaders.contentTypeHeader: 'application/json'};
final response = await http.get(uri, headers: headers);
