Answer 1

You can use dio package to send formData.

• First make formdata

  var formData = await formDataMap(
    checkbox: checkbox,
    taskDetail: _task,
    pageNumber: _currentQuestion.value,
    valueString: value,
    valueType: valueType,
    formFieldInstanceID:
    task.formFields[_currentQuestion.value].formFieldInstanceId,
  );
  

• Then add it in data parameter of dio_client Example

   _dio.putUri(
   Uri.parse(uri),
   data: data,
  

  );

Answer 2

You can use FormData(map) from get package.

FormData formdata = FormData(map);
post(url, formdata);

Answer 3

Use the dart HTTP package and convert your class SignupBody into JSON:

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

var url = Uri.parse('https://example.com/whatsit/create');
var response = await http.post(url, body: {'name': 'doodle', 'color': 'blue'});
print('Response status: ${response.statusCode}');
print('Response body: ${response.body}');

print(await http.read(Uri.parse('https://example.com/foobar.txt')));

(If that is the best choice, depends on your setup which you did not describe in your question. If you use Firebase use FlutterFire.)
