    You are not passing any url in http.post. Replace

        var response = await http.post(
      Uri(),
      headers: header,
      body: body,
    );

    With

        var response = await http.post(
      Uri.parse(url),
      headers: header,
      body: body,
    );

    Refer this documentation for detail information

    Use it like this to resove this issue

    // edit this line of your code
====> var header = {'Content-Type': 'application/json'};

// with this
====> var header = {'Content-Type': 'application/json; charset=UTF-8'};


// FULL CODE
class CreateGoalModals {
    Future<Add_Goal_Status> create_goal_WB(
    String name,
    String username,
    String email,
   String password,

) async {

final response = await http.post(
  Uri.parse(
    your_application_base_url,
  ),
  headers: <String, String>{

      'username': username,
      'email': email,
      'password': password,
    },
  ),
);


if (response.statusCode == 201) {
print('=========> 201');
  print(response.body);

  
} else if (response.statusCode == 200) {
  print('==========> 200');
  print(response.body);

  

  // after SUCCESS
  if (success_text == "success") {
    print('=========>  SUCCESSFULLY <===========');

  } else {
    print('========> SUCCESS WORD FROM SERVER IS WRONG <=========');
    
  }
  // throw Exception('SOMETHING WENT WRONG. PLEASE CHECK');
