Thank you so much! Appreciate your hard work. Just an advice though - try adding the source code or a link to the source code in the video description. It is really helpful to see all the code in one place after having gone through the video once. Keep up the good work !
how about i have a forum, and it have a list of 50K items? can it load like 30 and load another 30 if they scroll down? can you teach how to connect to an vanilla forum? i found from the internet, nothing.
i'am try to call only 1 data from this tutorial, and give 1 error from debug, its say "RangeError (index): Invalid value: Valid value range " ,than the data show up succesfully. whats would i do if i want to catch only 1 data sir? thanks...
Hi, I just followed what ever on your video tutorial but it seems it doesn't work on me at all, it showing me an error saying 'package:flutter/src/widgets/text.dart': Failed assertion: line 285 pos 10: 'data != null': A non-null String must be provided to a text widget Hope you could help me with this thanks
You are passing a null value to your Text widget and that's why you're getting that error, make sure that you initialize the variable you are passing in
i think it has something to do with the async task loading. You have to wait for it to load the data first. Maybe use a bool to show loading screen when there is no data loaded yet.
thank you very much, I really liked it. but i have one question is what i have to do if i want to update list of note, i meant how to clear list directly and get data again after delete
Can you say? From a Json in flutter how to display an object part and array of integer part only? For example, { "anObject": { "1" :"Item1", "2" :'Item2" }, "arrayOfObjects": [ { "item": 1 }, { "item": 2 }, { "item": 3 } ], "arrayOfIntegers": [ "1", "2", "3", "4", "5", ] }
For this video I just uploaded a random json i found to github, link below, but in the real world you'd most likely hit some kind of a rest api. You typically don't get a raw image in a json. Typically you get an image url and then display the image from that url. raw.githubusercontent.com/boriszv/json/master/random_example.json
Thank you so much and share a nice tutorials!! But I have some question, there are some error ```Dart Unhandled Exception: type '_InternalLinkedHashMap' is not a subtype of type 'Iterable', stack trace: #0 _MyUserState.fetchUserTest```. Is there any solution I can solve this?? Thank you so much that you take a look my comments
Now I solved this issue To solve this issue make sure you should not use 'Key' value in `Express.js`. -> like `return res.json({'key': rows}); convert to --> `return res.send(rows);
@@ProgrammingAddict It would be helpful for my next project but i need to finish what i work in 3 days so can you give me hint ? Would it be easier to fetch it by making it object ?
@@ProgrammingAddict thank you sir, I've seen the advantages of this plugin and I think it's really cool, but I'm still confused about what if I want to view the results of the json then it can be downloaded
This video is old, but this helped me so I'll comment anyway. Very straight to the point and helpful! Thanks
Interesting tutorial, but presented way too fast with your edits. Could be explained much better if you slowed down a little bit.
Thanks for your feedback
That's true
He rushed the tutorials
I noticed it as well but I just slowed down the video. That helped me
@@whatyoutubeviewerswant2628 Its true, I was the tutorial
Thank you so much! I've gone through like a few dozen tutorials over this and this was the only one that I could get working.

i have a quesiton. how do you get the link for json cause I can't create one
does this work if the JSON file is stored locally in an assets folder ?
Yes
Future loadNoteAsset() async {
return await rootBundle.loadString('assets/data.json');
}
Future parsePost() async {
var posts = List();
String source = await loadNoteAsset();
final parsed = jsonDecode(source);
for (var item in parsed) {
posts.add(Post.fromJson(item));
}
return posts;
}

Hey, I have a doubt. where do you upload these json files? Where did you fetch it from? And can we retrieve images from that json file too?
For this video I just uploaded a random json i found to github, link below, but in the real world you'd most likely hit some kind of a rest api.
You typically don't get a raw image in a json. Typically you get an image url and then display the image from that url.
