  factory EncryptUtil() => _instance;
  EncryptUtil._internal() {
    encrypter = Encrypter(AES(
      key,
      mode: AESMode.cbc,
      padding: 'PKCS7',
    ));
  }
  final key = Key.fromUtf8('aH5aH5bG0dC6aA3oN0cK4aU5jU6aK2lN');
  final iv = IV.fromUtf8('hK6eB4aE1aF3gH5q');
  late Encrypter encrypter;
  /// aes加密
  String aesEncode(String content) {
    final encrypted = encrypter.encrypt(content, iv: iv);
    return encrypted.base64;
  }
}

页面中使用

js 复制代码

// 加密后
var password = EncryptUtil().aesEncode(passwordController.text);
