I’m doing my TFG (it’s like a final project that you have to do when you are finishing your degree at university in Spain) on Flutter + Firebase and your videos are saving my life! Thank you!
I wish your videos have Spanish or English subtitles because sometimes I can’t understand what are you saying (my english it’s not really good), but I understand its complicated
Thanks!!!
Hey Andrea, the videos do have English subtitles, click on the CC button on the bottom right of the RUclips player (next to settings button) to show English subtitles.

Thank you
Welcome, Abdulazeez 😊
We can use or not one global key to in multiple container
thank you for your contribute flutter lecture.
i have some question about key, i think it is similar to state management...
one widget's value keep state(or key) and use the other widget.. what is different state management(bloc, riverpod) and globalkey?
Hey @user-nt3oq6cp5n 😀 GlobalKey uniquely identifies and interacts with specific instances of widgets, while state management handles the management and propagation of application state changes across the UI which can also help in good project architecture.
Hey folks, I just began with learning Flutter (coming from web). Could someone explain the shebang (!) in "final form = formKey.currentState!" at 2:14 ?
Why is that needed, what is it doing?
Rly appreciate any Explanation
Hey 😊, @sylensdrake9706! Check out this video: ruclips.net/video/5Ro-CZ8Msno/видео.html I hope this may help you
❤️
Sir I hope that you can make a video about states management.. because I am coding an app where I generate a list from a local json file, each taped item leads to a details page, where the use can press a floating button to mark it as favorite (the button changes color when pressed).
The problem I'm having is that when I go to the favorites list and I tap an item there it doesn't navigate to the details page .. it keep throwing error.
Any help would be greatly appreciated 🙏
