Add xxhash and ormsgpack to support LangGraph

[ndonkoHenri]

xxhash 3.8.0 and ormsgpack 1.12.2 wheels have been published for iOS and Android.

Let know if you face issues.

No, it still can't read the contents of the .env file on Android. Could you send me your code so I can take a look? Oops, it worked fine on PC when I tested it just now. @ndonkoHenri

So you can do this:

import os
from pathlib import Path
from dotenv import load_dotenv

assets_dir = Path(os.environ.get("FLET_ASSETS_DIR", Path(__file__).parent / "assets"))
load_dotenv(assets_dir / "example.env")

Yes, it just occurred to me that the new version 0.86 changed the default working directory to /data/data/xxxxxx/files/data, which is probably why I can’t access the assets folder properly. I switched to load_dotenv(pathlib.Path(__file__).resolve().parent / "assets/.env") and it now works. But I’m worried—does this mean accessing files inside the assets directory will be a hassle every single time from now on?

This approach has both advantages and disadvantages. Any files downloaded later will be saved to the data directory by default.

I can now retrieve values from the .env file. However, debugging my code further confirmed that this issue currently exists in Flet. #6682
