I am getting this error after doing that is mentioned at 10:30 I really love this app, as a beginner to flutter, i can understand the tutorial.

[@mmkamal]

Before watching all 3 videos: I thought now I know 10% on flutter

[@CodeXdev]

[@rvsme]

[@CodeXdev]

My pleasure

At 11:25 Don't make the new instance of provider (menuInfo) and use the instance which is coming from Consumer builder (value).

[@sankethb.k642]

Yes, since Consumer always gives us the updated value of menuInfo, there is no need to again get it from Provider.

[@AbdullahHattab]

11:00 won't work for null safety. will you update the code please

[@CodeXdev]

Clock app series is not compatible with NULL safety as it was created before NULL safety came. Sorry, but no plans to update in near future.

[@sisCAC]

Thanks bro!! Please, do more videos like these!! Very good material!!

*MIND BLOWN*

[@wasimkabir4398]

Please make the animation tutorial also

[@jabinaansari1447]

Yes, we'll love to watch animation tutorial.

[@amarmaharjan464]

Well Explained

[@sujalmanandhar8011]

If I try to NAVIGATE to another screen from inside the Consumer, then I get error message: This Overlay widget cannot be marked as needing to build because the framework is already in the process of building widgets... How can this be solved?

can yo please release the alarm tutorial iam searching a lot for a proper alarm project in flutter.

[@mechtarin]

okay I learn these stuff from you, but I want to know how did you learn these, they look complicated give me info I need that

[@guillermosantos7224]

Thank you so much for these videos

[@CodeXdev]

Glad you like them!

[@ta11p00]

Shows everything, and yet explains very little, I know these videos are great, but you need to pause and include some slides to explain how things work together, in order to take this knowledge you freely give and use it, a couple of moments of explanation (especially around providers and consumers) would be invaluable. Peace and love

[@CodeXdev]

thank you for feedback :)

[@syedafatima2889]

can you help me i can not understand why we pass there MenuType.clock in create : home:ChangeNotifierProvider( create: (context)=>MenuInfo(MenuType.clock), child: HomePage()), );

[@auliasabril1899]

thank you very much

[@juandavidmenesesgaleano8970]

type 'MenuInfo' is not a subtype of type 'String' The relevant error-causing widget was: Consumer how can i solve them?, thanks for your help

[@anilshrestha9989]

yes do page animation slider too :D

[@sorarose8360]

i mean that's cool and all but couldn't we just make a side nav bar ?

[@CodeXdev]

Its just design thing, you can create whatever you want. But SideNavDrawer is something not preferred now a days, people like to use bottom nav bar a lot.

[@sorarose8360]

@@CodeXdev thanks for uploading the vid and replying

[@abdelrahmanhedia9483]

Make animation bro

[@angrykorean3323]

where is god damn come form menuItems for map. you should check twice underbar or val name

[@CodeXdev]

@9:24 I have explained that I am using menuItem from data file, also I mentioned clearly @7:30 that we need to remove underscore ( _ ) from menuItem so that we can access outside.

[@angrykorean3323]

@@CodeXdev yea you right i skipped that my fault. thanks a lot a lot man anyway

I am getting this warning everytime E/flutter ( 5882): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: setState() called after dispose(): _ClockViewState#c83cc(lifecycle state: defunct, not mounted) E/flutter ( 5882): This error happens if you call setState() on a State object for a widget that no longer appears in the widget tree (e.g., whose parent widget no longer includes the widget in its build). This error can occur when code calls setState() from a timer or an animation callback. E/flutter ( 5882): The preferred solution is to cancel the timer or stop listening to the animation in the dispose() callback. Another solution is to check the "mounted" property of this object before calling setState() to ensure the object is still in the tree. E/flutter ( 5882): This error might indicate a memory leak if setState() is being called because another object is retaining a reference to this State object after it has been removed from the tree. To avoid memory leaks, consider breaking the reference to this object during dispose(). E/flutter ( 5882): #0 State.setState.

May be that timer is still running

​@@CodeXdev Yeah it was I checked the code in GitHub and fixed the issue.
