flet doctor CLI command

[ndonkoHenri]

Description

Running flet doctor in the terminal/console should output useful debug information like:

• Flet version installed (flet --version)
• Python version installed (python --version)
• Operating System info
• flutter doctor if flutter is installed
• ... (any other?)

Context

• Follow the steps of our Contribution guide to have everything properly setup. (for this issue, Flutter isn't a must-have, so feel free to skip its section)

• Create a doctor.py file here in the flet-cli package.

• Inspire yourself from the already existing files for the other cli commands.

• Ask questions if you face issues at any step or don't understand something. (Discord)

_{I marked this issue as "good-first-issue", and will self-assign myself in some days if not picked up by someone willing to contribute.}

App's requirements: pyproject.toml or requirements.txt.

@ndonkoHenri I have to have Flutter installed to do this?

[ndonkoHenri]

@OVECJOE no you don't.

You just have to follow this guide (ignore the Flutter-related sections): https://github.com/flet-dev/flet/blob/main/CONTRIBUTING.md

Of you are willing to discuss in a more interactive way, feel free to write on the Flet discord server: https://discord.com/channels/981374556059086931/1334494220727357463

Can I give my hands too, if I am not too late, Mr. @ndonkoHenri

[ndonkoHenri]

@AdreshSingh You can give it a try too. 🙂

Feel free to mention any issues you face or questions you have, here on gh or on Discord.

I updated the issue's description with more info btw.
