Flutter keeps throwing an error after adding local navigator

Hey Guys,

the title descries my problem. I made a few differences in the way that my routes work, since I wanted a more object-oriented way. I don't know what the f*** is going on, since I can't find any relevant differences.

MenuController is not found

hey guys, kindly help me out with this after creating menu I've came across this issue,

"MenuController" not found. You need to call "Get.put(MenuController())" or "Get.lazyPut(()=>MenuController())"
The relevant error-causing widget was
HorizontalMenuItem HorizontalMenuItem:file:///D:/BitEx/BitEx%20Web%20App/bitex/lib/widgets/side_menu_item.dart:17:11

Question: Menucontroller() error

I'm trying to follow your guide on skillshare, but i have some error i don't know how to resolve, following your code i was getting a null error so i started to fix it to run without disabling the null-safe mode as you can see on the repo: https://github.com/dabes/starter_flutter . but now i got this error and don't know how to proceed, if you could help me?

How can I navigate to detail page when tap on CellRow?

Issue with GlobalKey on flutter SDK >= 2.12.0

Hi

I can't use GlobalKey as you do on flutter SDK >= 2.12.0

For example i got the error below on NavigationController :

Error: Method 'pushNamed' cannot be called on 'NavigatorState?' because it ispotentially null.

I add also to change the topNavigationBar function to a StatelessWidget class extending PreferredSizeWidget and use Scaffold.of(context) instead of scaffoldKey to make it work.

I have no idea how to fix this error on NavigationController.

Blank white screen

not sure this is relate to the project specifically, but i get a white blank screen every time i run the project, have tried everything i could find on the internet

Duplicate GlobalKey

The following GlobalKey was specified multiple times in the widget tree. This will lead to parts of the widget tree being truncated unexpectedly, because the second time a key is seen, the previous instance is moved to the new location. The key was:

• [LabeledGlobalKey#bc309]
  This was determined by noticing that after the widget with the above global key was moved out of its previous parent, that previous parent never updated during this frame, meaning that it either did not update at all or updated before the widget was moved, in either case implying that it still thinks that it should have a child with that global key.

Multiple local navigator

Hello,

I followed your course, which was very good thank you! However, I have a question regarding multiple local navigators.

The functionality I`m trying to achive is the following:
1). User by default is navigated to the Login page (1), provides some data and presses the button
2). User is navigated to Login page (2), provides some data and presses the button
3). User is navigated to the home page.

I'm not quite sure to achive this with 2 local navigators... maybe you could assist me on that?

final Function onTap

Hi there,

There is an error when you are adding variables in the classes horizontal_menu_item, and menu_item. The variable defined is "final Function onTap"

In the InkWell(), there is an error on the parameter onTap : onTap.

The defined error is: "argument type 'Function' can't be assigned to the parameter type 'void Function()?'."

The solution is changing the type of the variable from "final Function onTap" to "final VoidCallback() onTap"

Thank you for everything so far, really appreciated!!

please fix this weird error or bug

Errors after apply url navigation

Good afternoon, after applying the url navigation changes, I noticed some problems.

When I click login on the authentication page, it looks like this:

And when I started the site, it asked me to put the "/" in the "not-found", and I did, but the page doesn't work...

I looked in your repository and the files are the same.

Sometimes an error of multiple use of GlobalKey appears, but I don't know how to solve it either...

Would you help me?

The Error:
