I have a few questions: - Why didn't you use Drawer ? - Can I use Redux instead of BLoC ? Thank you so much! Great tutorial.

@PrateekSharma1712 4 года назад

Drawer doesn't have the handle, that this one requires. Yes, you can use if redux is also state management technique in Flutter. I don't see many people using that.

@techieblossom 4 года назад

When you use container it will take full width, so you can give a default left padding. Then, your content will be behind the sidebar..

@kyungsooswifeu8240 2 года назад

I like this sidebar, however I'd like to use pageRoute instead of navigator/bloc provider etc... but when I do it becomes hidden I have to pull to see the sidebar. I removed the Sidebar_layout and NavigationBloc files only all the others are still there any solution please ? It's most likely because I am calling the sidebar as a drawer in every page, but I can't tell how to configure/change it.

@abasilis 2 года назад

Hi, first of all, thanks for the explanation, and the time invested in this sample. Not sure why I get an error in the 26:00 after replacing the variable to isSideBarOpenedAsync.data. The error is "A nullable expression can't be used as a condition. Try checking that the value isn't 'null' before using it as a condition." I know this video is more than two years ago, and I'm using Flutter 2.5.3, thanks again, and if someone here can help me it would be really appreciate it, to help me to get this sample finished.

@techieblossom 2 года назад

Okay. With the error description, I can say that isSideBarOpeneedAsync is null for maybe first time. You can write this isSideBarOpenedAsync.data ?: false in the condition.

@abasilis 2 года назад

@@techieblossom Thank you very much for your quick response. Assuming that this value will never be null, I wrote isSideBarOpenedAsync.data!. I continued with the video, and now I have two errors almost finishing. In the 54:38 NavigationBloc() I get the error "1 positional argument(s) expected, but 0 found." Also in the 58:35 when I pass the function onTap to the parameter onTap: I get the error "The argument type 'Function' can't be assigned to the parameter type 'void Function()?'". The whole project so far has been uploaded to my GitHub for you to check, in case I made a typo/mistake or the new versions of the flutter_bloc needs something else. Thank you for your time again, this means a lot to me. :) Github link: github.com/abasilis/sidebar_animation.git

@techieblossom 2 года назад

All are null related issues.. use onTap?.call() or onTap!

@techieblossom 2 года назад

What is the positional argument that it is asking for? At 54:38, can you tell that?

@techieblossom 2 года назад

because of this, the navigation bloc is requiring an initial state. NavigationBloc(NavigationStates initialState) : super(initialState); You don't need to have a constructor with (NavigationStates initialState), remove this and it will remove the error. Why this will work, because the super constructor will read already defined initialState. I will raise a MR, so check that.

The constructor itself has initialState, so it is still pointing to much newer version. Either have a version which doesn't have state in constructor or pass a initialstate from context: (context)=> NavigationBloc()

Other than menu item pages, how can we make same drawer available in other pages without using AppBar drawer method? I want same drawer to appear in other pages as well

@techieblossom Год назад

That’s tricky. Drawer is supposed to be available on first page only. For rare cases like yours, you will have to declare it again in other pages. The other approach is to load all pages as not scaffolds and only widgets. This way you have 1 scaffold only.
