Answer 1

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

Answer 2

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>{
'Content-Type': 'application/json; charset=UTF-8',
},
body: jsonEncode(
<String, String>{
'name': name,
'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');
} else {
print("============> ERROR");
print(response.body);
}
}
}
