我正在尝试从 API 获取数据。我需要从身体传递价值。

  signIn(String username,String password) async {
    SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
var jsonResponse = null;
 var response = await http.post("http://10.0.2.2:5554/api/login/login",
        headers : {
          "Content-type": "application/json",
          "Accept": "application/json",
          "charset":"utf-8"
        },
     body:{
       "username": '$username' ,
       "password":  '$password'
     });
