Flutter LONG LIST. Memory Efficient dynamic ListView tutorial: Flutter Dart Tutorial #2.8 

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 😀😍😘😎

You were born with teaching talent. Keep up good work.

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

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.

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?

you are a great teacher! i love this Flutter serie

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?

Thanks man

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

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

var listView = ListView.builder( itemCount: (listItems.length),

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

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

Awesome awesome awesome!

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 ?

you are a god

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.

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

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?

Great video. Keep it up

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.

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

What we gonna do with context?

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

Hello How do I display list elements randomly?

i'm trying same in my android studio, after item 999 RangeError (index): Invalid value: Not in range 0..999, inclusive: 1000

Hello , So i started learning flutter and i was watching this video and when i typed the codes and tried executing it , i found this following error : Compiler message: lib/Home.dart:22:13: Error: The argument type 'List' can't be assigned to the parameter type 'Widget'. - 'List' is from 'dart:core'. - 'Widget' is from 'package:flutter/src/widgets/framework.dart' ('/C:/src/flutter/packages/flutter/lib/src/widgets/framework.dart'). body: getListElements(), ^ Please follow back. Thank you !

ItemCount missing..

List long with images.

Nice, but very fast

at the end of the list I got a "RangeError (index)". how could I end the list with the last element?
