如果数据改为： {"appFlag":"true","currentPage":1,"pageSize":10,"productName":null,"riskClassCode":"06"} ，则完全匹配

代码如下：

你好，flutter web项目，调用SM3.hash(data);报错“Unsupported operation: Uint64 accessor not supported by dart2js.”
When the exception was thrown, this was the stack:
dart-sdk/lib/internal/js_dev_runtime/private/ddc_runtime/errors.dart 288:49 throw
dart-sdk/lib/_internal/js_dev_runtime/private/native_typed_data.dart 646:5 setUint64]
packages/dart_sm/src/sm3.dart 17:15 hashBytesToBytes
packages/dart_sm/src/sm3.dart 108:37 hash
请问怎么解决？

sm4和js版本的加密结果不一致， 导致后端解密不通用， 是哪里有问题吗？
js版本
let key = '7d5a493364f2f4250cb7963a17ee081f'
// 加密
let encData = SM4.encrypt('123456', key, {
mode: SM4.constants.ECB,
inputEncoding: 'utf8',
outputEncoding: 'base64'
})
console.log(encData) // biOgHi0QdDILAvpxPf8r1w==

dart
sm4Key = '7d5a493364f2f4250cb7963a17ee081f';
String encodeString = SM4.encrypt('123456', key: sm4Key);
String encData = base64Encode(utf8.encode(encodeString));

KeyPair keypair = SM2.generateKeyPair();
String privateKey = keypair.privateKey; // 私钥
String publicKey = keypair.publicKey; // 公钥

String cipherText = SM2.encrypt('我是中文', publicKey);
String plainText = SM2.decrypt(cipherText, privateKey);

print(plainText); // 打印结果为：b�f/N-e

请大佬有空帮忙看看。

用该库生成的publicKey和privateKey，publickKey交给服务端，服务端经过tutool库进行SM2加密后（均采用C1C3C2模式）得到的密文，用该库进行SM2解密，无法解密。

KeyPair 没有export，请大佬抽空添加一下。

const data = '12345';
final keypair = SM2.generateKeyPair();
String privateKey = keypair.privateKey; // 私钥
String publicKey = keypair.publicKey; // 公钥

test('加密和解密', (){
  String encryptData = SM2.encrypt(data, publicKey, cipherMode: C1C2C3);
  String decryptData = SM2.decrypt(encryptData, privateKey);
  expect(decryptData, data);
});

Expected: '12345'
Actual: ''
Which: is different. Both strings start the same, but the actual value is missing the following trailing characters: 12345
