Halo Sandi,
Kalau dilihat dari outputan errornya
```
Error: The argument type ‘String’ can’t be assigned to the parameter type ‘Uri’.
– ‘Uri’ is from ‘dart:core’.
var apiResult = await http.post(apiURL, body: {“name”: name, “job”: job});
^
```
disini kita bisa tau bawah masalahnya ada di type data yang dimasukan ke parameter http.post ya, yang mana function tersebut menerima sebuah Uri bukan sebuah String. sedangkan variable apiURL kamu isinya sebuah string. Jadi untuk mengatasi error ini kamu harus ubah String tersebut menjadi sebuah Uri dulu ya, sehingga code kamu akan menjadi seperti ini:
```
final apiUrl = Uri.parse("https://reqres.in/api/users");
var apiResult = await http.post(apiUrl, body: {"name": name, "job": job});
```
Btw, untuk cara pengubahan string jadi Uri ini ada di Praktik Rest API part II ya.
