The instance member 'key' can't be accessed-CodePudding

The key inside AES() does not accept because The instance member 'key' can't be accessed in an initializer.Try replacing the reference to the instance member with a different expression

 import 'package:encrypt/encrypt.dart' ;
      class className extends StatefulWidget {
      className({Key? key}) : super(key: key);

  @override
  _className createState() => _classNameState();
}

class _classNameState extends State<className> {
  
  final iv =IV.fromLength(16);
  var key = Key.fromUtf8('b75524255a7f54d2726a951bb39204df');
  final encrypter = Encrypter(AES(key));

CodePudding user response：

You can't instantiate key during the declaration. Just declare key and instantiate it in a second moment (for example in the initState()).

CodePudding user response：

You cannot initialize a member variable (key) and then proceed to use it in the initialization of another member variable (encrypter). The simplest fix is to add the late keyword before the encrypted initialization.

late final encrypter = Encrypter(AES(key));
