Я получаю исключение в проекте Flutter. Ошибка выглядит следующим образом:
Exception has occurred.
FormatException (FormatException: Unexpected character (at character 1)
<!DOCTYPE html>
^
)
Это отображается в строке «throw error». Код ниже:
Future<void> _authenticate(
String email, String password, String urlSegment) async {
final url =
"https://identitytoolkit.googleapis.com/v1/accounts:$urlSegment?key=AIzaSyC9Rz9CDv-_hc68I_wdvogF2ZnDHCpr2Y8";
try {
final response = await http.post(
url,
body: json.encode(
{
"email": email,
"password": password,
"returnSecureToken": true,
},
),
);
print(response.body);
final responseData = json.decode(response.body);
if (responseData["error"] != null) {
throw HttpException(responseData["error"]["message"]);
}
_token = responseData["idToken"];
_userId = responseData["localId"];
_expiryDate = DateTime.now().add(
Duration(
seconds: int.parse(
responseData["expiresIn"],
),
),
);
_autoLogout();
notifyListeners();
final prefs = await SharedPreferences.getInstance();
final userData = json.encode(
{
"token": _token,
"userId": _userId,
"expiryDate": _expiryDate.toIso8601String(),
},
);
prefs.setString("userData", userData);
} catch (error) {
throw error; //Exception is showing here
}
}
Сообщение об ошибке выглядит так, как показано на изображении (щелкните)
На консоли отладки отображается следующее сообщение:
