naive:// link rejected as "Invalid URL" in manual profile add — UI validator only accepts http/https/ftp

4.1.1

What Happened?

Cannot add a naive:// proxy link in Hiddify. The URL input field immediately shows a red border ("Invalid URL") before any connection attempt. The backend (ray2sing) supports naive:// but the UI rejects it.

The isUrl() validator in lib/utils/validators.dart uses a regex that only accepts https://, http://, and ftp:// schemes. All proxy-specific schemes (naive://, vless://, vmess://, etc.) are rejected at the UI level when using "Add profile manually".

Additionally, LinkParser.deep() in lib/utils/link_parsers.dart only accepts hiddify, v2ray, v2rayn, v2rayng, clash, clashmeta, sing-box schemes, so QR code and deep link paths also reject naive://.

Minimal Reproducible Example (MRE)

1. Open Hiddify v4.1.1 on Android
2. Tap "+" → "Add profile manually"
3. Paste: naive://testuser:testpass@example.com:443#my-proxy
4. Input field immediately shows red border with "Invalid URL"
5. Also tried via QR code containing the same link — same result
6. Also tried deep link hiddify://import/naive://user:pass@example.com:443#tag — link not recognized

Expected Behavior

The link should be accepted and parsed by ray2sing, which already has naive:// registered in ray2sing/convert.go:

"naive://": NaiveSingbox,

The UI and deep link layers should not reject schemes that the backend can parse.

Additional Context

The issue affects all input methods (manual paste, QR code, deep link). The naive protocol was added to ray2sing in 2024 (issue #611) but the UI validator was never updated to accept it.

I didn't know how to connect naive to Hiddify. I tried what you described (naive://log:pass@your.domen:443) — it connected, and it worked.
The only thing I don't understand is how it works. In the Naive repository, they recommend downloading the client—the Naive binary file — and running it that way. Does Hiddify use the same binary?
Regarding your connection issue, you may be using incorrect credentials. Please double-check them.

To be more precise, I constructed a link in this specific format.
I performed this on Windows, using Hiddify version 4.1.1.
I assembled the link, copied it, tapped the "+" button within the app, and selected "Add from Clipboard." For some reason, the configuration adds successfully this way—yet it fails to add when using the manual input button.
Prior to this, I had downloaded the Naive binary file; however, I never manually linked it to the system myself. It is possible that it automatically registered itself in the system's PATH environment variable, and Hiddify is subsequently detecting and utilizing it. I may be mistaken in my assumption, but the setup is currently working for me—and, unlike VLESS, the connection speeds are noticeably faster.
On Android, however, it fails to connect via Hiddify. I installed the Naive plugin, but it still refuses to establish a connection; curiously, though, it works perfectly when used through Nekobox.

Yes, I was also able to add a link with naive:// using the clipboard button, but I can't paste it as a string when adding it manually. However, if I paste it using the clipboard button, the profile activates and works fine. Clearly, it's a UI bug.
