Can I use this package to encrypt/decrypt files?

Is it possible to encrypt and decrypt files using this package?

Yep we do something like this.

 Uint8List enc = await SecretBox.encryptBytes(
      await file.readAsBytes(),
      nonce,
      key,
    );   
  await file.writeAsBytes(<int>[]);
  await file.writeAsBytes(enc);

 Uint8List decryptedBytes = await SecretBox.decryptBytes(
      await file.readAsBytes(),
      nonce,
      key,
    );

I know I can set a custom key but what is nonce could you please clarify?

And what is this line doing?

await file.writeAsBytes(<int>[]);
