问题描述

如何在Dart中编写字节数组?我想实现此功能，但这是Java代码，其中包含 byte [] .也可以用Dart编写吗?

How do I write a byte array in Dart? I want to implement this function, but it is Java code with byte[] in it. Can it be written in Dart as well?

public static byte[] encrypt(byte[] key, byte[] data) throws Exception {
    try {
        return performCipher(Cipher.ENCRYPT_MODE, key, data);
    } catch (Exception e) {
        throw new Exception(e);
    }
}

推荐答案

您正在寻找的是 Uint8List .它等效于Dart中Java的 byte [] .每个单个值在另一种语言中都具有等效项，因此几种语言中的 byte [] 类似于:

What you are looking for is Uint8List. It is the equivalent of byte[] of Java in Dart. Every single value has an equivalent in another language, so byte[] in a few languages is like:

1. Java: byte []
2. Dart: Uint8List
3. iOS: FlutterStandardTypedData->typedDataWithBytes
