Thanks! Greetings from Chile

[@bashka411]

It's perfect. Thank you

[@javohir307]

this really helped me, thanks

[@red010182]

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

[@nahiyanalamgir7056]

Yes

[@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?

[@AhmadAshraf-qs7ud]

this is very helpful ... thank you

[@sr_saad]

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.

[@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.

[@JayNirmalkarx]

no need to provider

[@findsarfaraz]

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

[@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”)
])

[@Ayoub_Shnab]

Nice
