上边的解决方案是与原生做个bridge，使用原生来加解密。

其实直接用Dart原生就行

上代码

import 'package:encrypt/encrypt.dart' as XYQ;

void main() {
  final key = XYQ.Key.fromUtf8('my 32 length key................');
  final encrypter = XYQ.Encrypter(XYQ.AES(key, mode: XYQ.AESMode.ecb));
  final text =
      "A set of high-level APIs over PointyCastle for two-way cryptography.";
  final encrypted = encrypter.encrypt(text);
  final decrypted = encrypter.decrypt(encrypted);

  print(
      decrypted); // A set of high-level APIs over PointyCastle for two-way cryptography.
  print(encrypted
      .base64); // +H8VseqZhaZaK8EUh+K2jlHXBFbRA/dHkpPDf0fN+YaNro9ofBNlLsVtrkmmiulBoBiS4EQE7djVvsouuVyIXwe3lQogMzWcdAULNBSrSRM=
