Everything is fine but one thing is missing stream close karna reh Gaya , stream close karna is necessary so we don't face any memory leaks problem
Great observation! I'll pin this comment for everyone to see 😁.
But when using a StreamBuilder, it closes its associated stream automatically when the widget is removed from the widget tree.

i am facing one error (stream has already been listened to) in TabBarView on change of tab and return back to tab please provide a solution thanks
you need to use brodcast stream to have multiple listener/subscriber
i have change StreamController() to StreamController.broadcast(); which resolved my issue.let me know please is this a right way?
Yes, broadcast streams can be listened to more than one time.
Sir i am using tabview its not refresh stream when i change tab
I use two tabs both tabs contains same stream when i update stream and change the tab then new tab dont show updated stream
Hi sir, can you tell me how to dispose the streams? I'm facing an issue, developing an e-commerce app, updating my profile information but when I logout and then login from another user, it shows the previous user's profile info, and someone told me to dispose the streams, can you please help me in this regards or provide any reference for this solution.
If using a streambuilder, the streams will be disposed automatically.
But if not using a StreamBuilder you can store the streamsubscription as a variable and then cancel it later.
StreamSubscription subs = newStream.listen(handle);
Then whenever you want to cancel it:
subs.cancel()
@@RohitSemriwal yes sir i'm using streamBuilder( ... ) but whenever I log out and again login with some other user profile it is showing the older one profile information, then what can be the issue according to your knowledge?
can you help me for StreamProvider?
What's the issue?
@@RohitSemriwal i don't know how to use that
Good... but background music is very disturbing...
I've fixed it in future videos 😁
It would be better if it is in English... ^_^
I'm planning on making a channel in English as well, will notify you when it's done. Thanks for watching 😁
Can you please not put an english title to a video that is in hindi?
The title clearly says Hindi at the end. Also I select language Hindi while uploading the video.
Also the thumbnail mentions that the video is in Hindi.
I get what you're saying and sorry for any inconvenience caused.
