Access local website from another computer in the same network

I recently wrote a web using Flask, and made the host='0.0.0.0', port=5000.

I can access the web with 127.0.0.1:5000 or localhost:5000 or 192.168.1.12:5000(my IP), but I can only do this with the computer that runs the codes.

How can I access the website from another PC in the same LAN? I have tried all the method I can find online. But none of them worked.

I'm running the code on windows 10. Please help!
