How can I write byte array in Dart?

问题

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);
    }
}

回答1:

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

I recommend looking at the documentation for more: https://flutter.dev/docs/development/platform-integration/platform-channels#codec
