I have a question that why ‘Count ’ construction method is called when it excute Function(int),

[@tejasmd8143]

Love the content on your channel, multiple useful videos. Kudos!

[@yuhabkat]

what if count is a StatefullWidget, where do i put count? in the State?

[@alwidfamily]

CMIIW so the voidcallback use if the callback doesnt have any parameter. and the function use when the callback return any parameter. am i right?

[@gfdsggsdfs9472]

tnx

[@florianmarcu1366]

Hello ! I noticed you can use the setState() method when setting the onCountChange() argument. However, in my case, i can't do so because flutter warns me that I am trying to pass a non-static method as a parameter. Is there any solution to this?

[@paulhalliday]

Want to put your code on GitHub so I can take a look?

[@javohir307]

could you tell us a plugins and fonts you using in vscode . Because yours looks beautiful ;)

[@paulhalliday]

Thanks Javohir! I have videos on my terminal and font setup here: th-cam.com/video/8q0KITkJee0/w-d-xo.html

[@red010182]

Since Count widget is stateless, does this mean that any change of count variable leads to re-construct Count widget?

[@nahiyanalamgir7056]

Yes

[@MuhammadAmir-mf9xt]

Amazing 👍👍👍

[@fiendsgaming7589]

what fonts are u using in vscode?

[@Iamsafuvan]

Thanks brooo👍👍👍👍

[@SAlpay-fj6gf]

Thanx for this great tutorial. Just try to understant the logic. On the counter dart why did we extand our class with stateless widget? Cant we open normal class and without that build function in class?

[@Ayoub_Shnab]

Nice

[@shadirvanislive]

love your editor font please tell me which is it

[@if6086]

Excellent.

[@faisalfotoh1909]

please can you explain all methods in this vsCode Dart Data Class Generator?
Features
The generator can generate the constructor, copyWith, toMap, fromMap, toJson, fromJson, toString, operator == and hashCode methods for a class based on class properties or raw JSON.

[@angelocampo1017]

Hello, what visual studio theme do you use ?, looks great

[@internetcollections6453]

Great video... Which extension you are using in VS code for this type of beautiful text and display?

[@findsarfaraz]

What if these + and - Buttons are on parent widgets.... and you want to do the increment.

[@fxman9722]

Sir thanks for the tutorial. I am new to flutter. I have a problem passing a String variable from Scaffold body to a fixed button created using bottomnavigationbar which is outside the scaffold body but in same screen. Can I use call back to get value of string in bottom navigationbar or do I need provider. Sir plz give me some hint.

[@JAY-bo7tg]

no need to provider

[@abhisheks8464]

I am student, Plz anyone tel me where and when use child and children in widget using flutter, I am totally confused

[@paulhalliday]

Child is used for a singular widget, and children is used for multiple widgets.
An example here would be:
Container(child: Text(“hello”))
Column(
children: [
Text(“hi”),
Text(“ho”)
])

You are moving too fast for real beginners.
