if you have problems with the data.length; fix it with putting 'AsyncSnapshot' before snapshot in the builder parameter; builder: (context, AsyncSnapshot snapshot)
Thank you for your tutorial. It really helps me, find a lot but most of them not working with flutter 2022. Containing many bugs. One bug to fix, is to add AsyncSnapshot before snapshot "builder: (context,AsyncSnapshot snapshot)" Anyway, I have just subscribe to your channel.
This tutorial ignores two important things that video makers keeps ignorering all the times. (1) Showing an error if network is not available. (2) Detecting if returned Map(data) is empty and show "not data text" or something and probably showing a loading spinner for the slow networks instead of keeping users waiting on a blank screen, but loading spinner isn't important. Anyways it was a great tutorial. Many thanks
thanks for this tutorial video it really helped me to build my mobile app, (analytics dashboard for social media content creator) which is now live! it has been few days only but this video was very helpful! API was a bit trickier but could make it work :) cheers
Yo!!! you just got a new subscriber, your lecture is suscint and clear. Wow!!! i love you sir. Keep up the good work. i'll definitly watch all your videos and drop feedbacks.
Last few days i try to know flutter api integration. so I watch lot of api integration videos on UA-cam. but all the videos are uploaded minimum 4 month ago. So all my tried was failed i facing lot of error. finally I watch this video i see lot of different from that old videos. Thank you for this video.
Thank you bro it's too easy and helpful, I saw most of the video but that's not clear and give more errors, but in this video is perfectly used, Thank you so much 🤝
Hi :). I'm doing everything like you and here what happens: '_Map' is not a subtype of type 'Iterable' What am I doing wrong if you don't have this issue? I start to become powerless...
thanks for the tutorial bro, but i have an error like this "The property 'length' can't be unconditionally accessed because the receiver can be 'null'. Try making the access conditional (using '?.') or adding a null check to the target ('!')." what should i do?
After run this code I have faced some problems. Like.. 1.The method '[]' can't be unconditionally invoked because the receiver can be 'null. 2. The property 'length' can't be unconditionally accessed because the receiver can be 'null'. Please tell me what was the solution.
I am facing the error on snapshot.data.length . Error Shows In The Property 'length' can't be unconditionly accessed because the receiver can be 'null',
I tried this code. But i am facing an error at snapshot.data.length Showing that - property length cannot be unconditionally accessed because the receiver can be null. Can u pls tell me hw to correct it.
I am new to flutter , so I don't know details. I am getting "the property length cannot be unconditionally accessed because the reciever can be null" error. Found no proper solution in online. How do I solve this?
Bro I am getting this error (error: The operator '[]' isn't defined for the type 'Object'. ) did the same way as u. snapshot.data[i].country this is showing me error I've been trying this from 2 days help me out but while trying to print the data in for loop at 7:35 it is getting printed
I had the same problem so Someone on UA-cam suggested that we should use (context, AsyncSnapshot snapshot) instead of (context, snapshot). And then I got the length with this snapshot.data!.length
i understood this video of yours but in my emulator its showing WAIT as i created if(snapshot.data == null) return container(child: Text('WAIT")) meaning My SNAPSHOT.data == null what the heck is the problem i cant understand
im doing the same as the video, but im reciving a error in snapshot.data.lenght: The property 'length' can't be unconditionally accessed because the receiver can be 'null'. Please, can someone help me?

Brother so here is the error The Getter length isnt defined and []. Isnt drfined for type OBJECT
I think this code wouldn't work any more because of null safety

Check if you have upgraded to null safety and update the code accordingly.
