itemBuilder: (context, index) ====> here, please explain how context and index will be resolved. what is index element and how this is called and how the value of index is decided?

[demotics]

Thank you so much! You are very good. Lessons are clear and succinct. You are very helpful

[s_nawaz]

My debugPrint is not working with the list view. It is also not showing any error.

[domainadministrator]

Very nice tutorials. I have completed Dart tutorials and now on Flutter. Very clear and concise. Keep up the good work. Just a small thing, add itemCount = 100 to item builder in order to limit the list to 100 items, otherwise it was giving error on android emulator when the list is scrolled.

[PivotGuy]

Your videos are cool, but could you tell me where the index comes from? I mean where are we giving it to the itemBuilder, or which function or Widget do that?

[Jobic-]

Okay, here we go.
I got a video from a friend and I saw how exciting it was.
You made the definition of "complex" to be something else.

Having watched the video, I vowed to look for your channel. I've watched all your playlist on Flutter but I can't comment on it all.

So, here's an appreciation from A Nigerian friend.
Thanks for all you do.
You're appreciated.
Thanks once again 😀😍😘😎

I got everything you taught except from one thing that what actually context and build context arguments does?

[MdYousuf-gwdn]

what i have to do if i want to show 1000 different string? do i have to change inside generate? and how? can anyone explain please

[michaelb]

var listView = ListView.builder(
itemCount: (listItems.length), <<< That's the missing line to stop range exceptions that happens when you scroll past the end of a list.
itemBuilder: (context, index){

How to implement LongList or ListView from below some widgets.
Suppose if I have:
Widget 1
Widget 2
Widget 3
I want to implement LongList from below widget 3. Whenever I try to implement ListView below widget 3, the screen is blank, nothing appears. What might be the reason?

[nirjanmunshi]

don't know why but if i want the list item count 100, it shows error after item 99 and the error is RangeError (index) : Invalid Value: Note in range 0.99, inclusive 100

[syedimam]

please make a video on build method, Builder, build context, context it is so confusing. please

[mithuns]

I am getting an error "The method builder is not defined for the class ListView"

[Nithinjith]

Is it possible to make a Toast instead of debugPrint()? That will be more meaningful. I don't know whether we can make a toast in flutter.

[refreshing_morning]

Nice video.
Can each ltem in the long list have their own name. Also can I assign an ontap function to different items when click..according to the video the ontap function was applied to all the items.

[testtest-ytss]

Hello
How do I display list elements randomly?

[josejaimes]

Great tutorial! The additional information is the same as previous listeners have made. How do I do to control the red screen when the index > 1000 ?

[Solar]

you are a great teacher! i love this Flutter serie

[muhammadfaizan]

Hello there
First of all thanks for your efforts
I wanted to notify that you forgot to add itemCount in ListView.builder() constructor which causes RangeError(index ) error
