Really great. Would love to see some examples where we use multiple .py files imported to a main file, and setup and app with different page views (e.g. settings, or switching from login to the main app, etc. To understand routing / flow better.

[SecurityFirm]

amazing, after long time i see a real person with real knowledge to build real app, without ai assistants. CONGRATS DUDE💐🍷

[arcade_mntra]

Neat quick tutorial. No fluff and easy to follow as I have worked with flutter before. Please make more tutorials using Flet.
Flet is a game changer project, brings flutter to python. UI development feels seamless over working with CSS.

Would also love to see a multi-page application. For example, to build an app that contains all my "mini apps". On the main page, I just click the button (e.g: "Weather Info" would open your app built in this video above) and then it opens as a dialog, meaning you have to close it before returning to the main menu. Or whatever layout approach you think is recommendable or cool for multiple page applications.

Dude, so nice to see this video.
Been struggling a bit to get nice tutorials for Flet. Most don't have speaking and I was getting discouraged about the apparent lack of community support.

[aquelaquelaquelaquel]

I liked it a lot! Please do more!! I am really interested in this framework! Many thanks for your content!~

[wRatte]

Also (since I'm already flooding your chat with tutorial ideas XD), since Flet is for mobile, desktop and web, could you do a tutorial that shows how to deploy Flet apps to mobile, desktop and web, respectively? For example, even though I know how to run it on desktop by using VS Code or PyCharm, how would one create an installer or exe for the wife and kids to just run it without needing to do a course in programming first.

[erianaMarie]

Please do more!! I am really interested in this framework!

[BillyLinux]

Another awesome tutorial! Thanks for all your work!

[Rupam-Tech]

Thanks Josh. Can you please also show how to access this app from a mobile (android or ios device)?
I was able to access it on laptop/desktop as an app, and also on browser as a web app.

On another video I see a command to run it on android as: flet run <app-name> --android. But i couldn't run it myself. If you can cover that part, how to create an android and/or ios app from it, it will be great. Thanks.

[gamezplayground]

Hey! Amazing work with Flet—really loving the simplicity and power. Quick question: does Flet support push notifications (like Firebase or local)? Would love to see a demo if possible. Thanks!

[joseescamilla]

Thank you for adding Spanish dubbing to your video. 🙏🏻
YouTube recommended this video to me, and I was delighted with your way of explaining.🤓
Please keep adding Spanish dubbing to your future videos. 🙏🏻

[jcurwen]

Nice video.
I would like to see you make an android apk from you flet app.

[wombaat]

Very neat tutorial, thanks Josh. Is there any angle that we can integrate machine learning models like weather predictions? and maybe how to include offline maps and store local weather data for low-connectivity?

[immaterial_vivi]

> No Flutter needed!
But this is flutter, just with a python wrapper? No dart needed would be a lot more accurate, this got my hopes up it was actually a new way to make desktop UIs :c

[michaelfigueiredo]

I would love a video where you build out a dog walk tracker app. using maps to track the dog walk and then create an invoice and track walk history.

[sergiop]

Great video! I had no idea about Flet framework. Thanks for sharing!

[TeckTales]

Sweet I've been waiting for this..

[wRatte]

Would love to see a master detail CRUD screen.
For example, on the top list, show orders (E.g: date, total, customer name, etc.) and on the bottom list, show the selected order's transaction items (E.g: T-shirts x4, Shoes x2, Hat x1, Fanta Orange x1).

The data could be saved anywhere - SQL/SQLLite3/JSon/whatever.
I'd just like to see how Flet handles what I consider the basics of data interfacing, which is how to handle a master detail relationship.

I eventually used "hidden" fields and columns to manually track the DataTable selected indexes and primary/foreign keys, so that when I clicked save, I was able to update both my data and DataTable (on screen) without issues. I'm really hoping there's a better way to handle that.
