- In this video I discuss passing data between Classes using setState, specifically passing variables back to the parent statefulWidget in a somewhat simple Flutter example.
Chapters:
0:00 Intro and initial setup
1:42 Adding MaterialApp,Scaffold and AppBar
3:35 Adding an ElevatedButton
4:25 setState inside the same Class

Did the diagrams help? And did I use the word "Redundant" correctly? haha! Would love to hear your thoughts!
The diagram is awesome, it was very helpful, i really need visual aids like that while learning so thank you!
@@hope4ul Excellent!!!
@@LearnFlutterwithMe good stuff mate
@@Andreasonline3 thank you!
the diagram is awesome, it makes me understand what you are doing
true OG for typing all the code by hand
The way you explained everything from the basic level is awesome.
Don't normally comment but want to help your ranking in the yt algo. Thanks for the great tutorial!
Your videos are greatly detailed. Love the way you explain thoroughly.
Really liked you video because of the simplicity of your explanation, as a beginner it's really helpful.
I like the way you are teaching, short and brief to the point. Easy to understand. Thank you very much.
Great tutorial. Very clear explanation and on point. Also your diagram is a big help to understand what's happening.
very good example for callback, thanks
You voice takes away half the stress I built through watching videos of other flutter related channels.
What a nice thing to say! Thanks!
Thank you for the great lesson. Clear and simple but very effective!
thank you! and thanks for watching!
Excellent Teacher!!!
Really good explanation. Thank you.
exactly what i wanted thankyou
best explanation for callback functions
Excellent Tutorial! 5 Star!
so clean. thanks a lot Mr.
amazing. Great way of expression thanks
I watched and he never used autocomplete. What a genius!
Thank for video,you one of best in explanation who i saw!
Glad it was helpful!
Great tutorial. Finally a video that is simple and easy to understand. You are a great teacher. My only suggestion is to change the 'clicking' sound, it's too harsh and distracting.
Thank you! Yeah I don't use the sound effects as much as I used to, but I do still use them some and should probably use them more than I do haha! So I'll listen back to this video and make sure I get that corrected for the future. Appreciate the feedback!
Great video! Thanks a lot!!!
Wow, very knowledgeable tutor, this video is just perfect, many thanks.
Thank you so much! Thanks for watching!
This video was so amazing...Thanks a lot...I'm from Brazil!!!!
Nice to "meet" you, thank you and you're welcome!
Superb....Thank you very much 🤗👌
Very Useful ❤
I like your videos a lot, thanks for your time....
thank you for the video.
Thank you!!
thank you very clear and to the point
thanks for watching!
Thank you bro!
Great. Thank you for the video.
You're welcome!
this is more explanatory. will like you to do a full course on Getx state management.
once again you are indeed a genius (nothing like auto complete throughout the video )
I'll see what I can do! Thanks!
you are my hero
very good videos :)
great video i like it way of teaching.
if you want to grow more faster than other
you should create video in one topic zero to end like topic like riverpod
create clone code and more
you should try once
thank you
Thank you! Very clear explanation. I have a question regarding forms. Is there any way we can differentiate textformfield and button, and put them in different classes, keeping the communication between them and validating the form when the button is pressed? thanks a lot.
Also. regarding your videos. I really enjoy them. I think that the music in the background is very calming, and for me, atleast, it somehow makes things more clear. The diagram: I had to stop the video and glance at it to understand, but when I did stop the video, and looked at it, it all clicked :).
P.S I really do believe that you are gonna get more views eventually, dont stop the videos and have some patience, having seen many videos and not only flutter tutorial, i got to say that yours are one of the best.
Thank you so much, that's great to hear! I really appreciate it! So the short answer is yes that's doable... getting the elements into classes is straight forward, the validation is the question. Let me think it out and I'll get back to ya!
very good
Thanks!
Hi, is there a way to pass multiple data to a stateful class?
here, in this exercise... i can call or declare Function with nullSafety...?
How we use inbuilt function like list.remove inside setstate method..??
this diagram teachin damn dude wp..
how to call future me4thod of stateful widget in another stateful class without using static before the method?
Wich plugin do you use to get the widget-tree visualized as you type along?
It's unfortunately not a plugin, I create the graphics and add them when editing the videos. but it would be a cool one!
hmm, i'm trying this with 3 classes: 1 class "textbar with the var", 2 class " the buton with the var = "newtext" , and the 3 class wrap 1class in column and stuff. this dont work on that :\
Do you have a flutter series?
Are you asking me if I have a Flutter course somewhere? Not yet but I hope to in the near future! I'll let you know if/when I do!
@@LearnFlutterwithMe thanks I have subscribed your channel I'm waiting your notification
jesus man you are typing way too much. VS Code snippets gives you all the code with a press of a button. Your coding is very inefficient.
Yeah I did it that way on purpose. It’s an instructional video. Thanks for watching!
