toastr shows up again when trying to go back about toastr HOT 5 OPEN

Hello @2jiwon, thank you for using the yoeunes/toastr package. I noticed that you are currently using an outdated version of the package. To resolve any potential issues, I would recommend upgrading to the latest version by running the following command: composer require yoeunes/toastr::^2.3.

Additionally, I suggest removing all the code related to the outdated version from your blade template. This should help ensure that the latest version works seamlessly with your project. Thank you again for using this package, and please let me know if you have any questions or concerns.

@yoeunes Thank you for your reply. I tried what you suggested composer require yoeunes/toastr::^2.3 then it says

 [UnexpectedValueException]                                                
  Could not parse version constraint :^2.3: Invalid version string ":^2.3"

so I also tried composer require yoeunes/toastr^2.3 just in case, but it didn't work either.

@yoeunes oops, nevermind. it was because my composer version. I was able to update to 2.3.
However, the situation that showing up twice is still exists.

please remove all this code from your blade template:

@if (Session::has('success'))
         <div class="row justify-content-end">
               <div class="col-3 col-align-self-end alert alert-success alert-block">
                   <button type="button" class="close" data-dismiss="alert">×</button>
                       <strong>
                          toastr.success("{{ $message }}");
                        </strong>
                 </div>
          </div>
