ProfilePage | A bootstrap page I use as profile / CV

I am very new to Dart, and coding in general. I have produced this code after watching tutorials on YouTube. For the most part, I have been able to troubleshoot most of my problems on my own, yet I cannot figure out my most recent errors. Here I made a TextEditingController on a page(Which worked fine BTW), and later I shifted to another page to make the code clean. But they stopped working.

I'm using Firebase v9 and react-router v6. I haven't used v6 so this was quite confusing. How can I make it where the guest user can only access the login page. Only users who were logged in can access the homepage and other pages.

Everytime I'll reload any page, it will show this in the console but it will still direct the user to the right page :

No routes matched location "/location of the page"

How can I use a private route for the profile page?

I am building a Next.js project where I want to implement private route similar to react-private route. In React this can be done by using react-router, but in Next.js this cannot be done. next/auth has the option to create private route I guess, but I am not using next/auth.

I have created a HOC for checking if the user is logged-in or not, but I'm not able to redirect the user to the private he/she wants to go after successfully logging in. How to achieve this functionality in Next.js? Can anybody help me in this?

This is the HOC, I used the code from a blog about private routing.

I'm using "Sharpnado Tabs" and having problem in firing tap event in middle "BottomTabItems". I have 5 bottom tabs as you can see the attached photo and the areas outlined with black is firing tap event and changing the views accordingly. However, the areas marked with white, is not doing anything.

EDIT

The 5 tabs are spread evenly across the bottom panel. I have set the middle tabs' background to red to see the area they cover and where the touch is working. Setting InputTransparent="true" removes the touch event from the whole area of the tab.

Details: I have top level routing like this:

I have an error message as so when trying to convert an existing app to use react-router v6:

Error: A is only ever to be used as the child of element, never rendered directly. Please wrap your in a .

here is my App component (BrowserRouter wraps the app, custom Router component is a child):

I am designing a users dashboard in React, wherein User logs in and navigate to his dashboard with other links such as Archived, Profile and Settings. My Login and then Navigating to HomePage is working fine. I have designed the Dashboard, Archived, Profile and Settings Page Links in Sidebar. Now when I am navigating to the Links. It takes me to a new URL path and my Sidebar disappears. I want my sidebar to still appear on all pages as long as I am logged in.

Below is my App.js where I have designed the upper level route:

I am trying to create a hyperlink to link each and every image's URL in my code so that a user can be directed to another page with information about the image that was clicked on. How do I go about doing that?

I am trying to delete and update a list of details in flutter. For that i used doc('document_id') which was given as a solution in another stackoverflow question. I tried some another solutions given in stacker flow too. But nothing fork for me. But if I give a specific documentID I am able to delete that. Also how can I pass the selected data to update page too.
