Getting Format Exception while parsing token with '|' in jsonDecode()

Question

Getting the format exception while passing the token with '|' inside jsonDecode().

final SharedPreferences pref = await SharedPreferences.getInstance();
    value = pref.get("token") as String;
    if (value?.isEmpty ?? true) {
      return null;
    } else {
      final Map<String, dynamic> map = await _parseJson(value);
      return OldToken.fromJson(map);
    }

static Future<Map<String, dynamic>> _parseJson(String text) {
    return compute(_parseAndDecode, text);
  }

static Map<String, dynamic> _parseAndDecode(String response) {
    return jsonDecode(response) as Map<String, dynamic>;
  }

Cant see your issue due to images blocked here. Better provide in text form. — Dev, Feb 15 '21 at 05:21
I think it would help others understand better if you could post the fragment of JSON input on which it's failing. — Robert Dodier, Feb 15 '21 at 05:23
I am getting format exception inside jsonDecode() method @JanviPatel — gowthaman C, Feb 15 '21 at 05:26
I think the problem may be that this is just a string and not a json — Antonin GAVREL, Feb 15 '21 at 05:33

When you use SharedPreferences you retrieve directly a String, so you don't need to decode a json value.
