jsafe #

Resilient JSON parsing utilities and json_serializable converters for Dart/Flutter.

Why #

Backends drift. Fields go null, types flip ("1" vs 1), arrays become singletons, etc. jsafe makes your parsing forgiving without hiding problems.

Highlights #

• Safe scalar parsing: str/int_/dbl/bool_/num_ (+ nullable strN/intN/...)
• ISO & epoch-millis DateTime parsing
• Enum parsing with fallback
• Deep getter: JSafe.getAt(map, 'a.b[0].c')
• mapList for nested lists
• omitNulls for clean toJson
• Debug/strict flags to surface backend regressions in dev
• json_serializable converters included

Quick start #

import 'package:jsafe/jsafe.dart';


final map = {
'id': '42',
'price': '1,299.95',
'ok': 'true',
'createdAt': '2025-10-22T08:15:30Z',
};


final id = JSafe.int_(map['id']); // 42
final price = JSafe.dbl(map['price']); // 1299.95
final ok = JSafe.bool_(map['ok']); // true
final ts = JSafe.dt(map['createdAt']);
