Help Needed: Null Check Operator Used on a Null Value Error in Flutter Web Release

Help

Hello Flutter Community,

I am currently facing an issue with my Flutter web application when I try to navigate to the “/admin” route after running the release build. The error I encounter is as follows:

Error :-

1Uncaught Error: Null check operator used on a null value
2    at kT.gt9 (main.dart.js:66151:18)

This error seems to occur when I attempt to navigate to the “/admin” route. I have checked my code for any potential null values, but I am unable to pinpoint the exact cause of this issue.

You can view my website at coct.vitapath.in for more context.

Here are some details about my setup:

  • Flutter version: 3.29.2
  • Dart version: 3.7.2

I would greatly appreciate any guidance on how to resolve this error. If you have encountered a similar issue or have any suggestions on what I should check in my code, please let me know!

Thank you in advance for your help!

Best regards,
Mohit Khatri

Can you share the code behind this web page? Will make it a lot easier to analyze where the bug are in the Dart code.

The issue has been resolved. The error was occurring because changes were not reflecting on Hostinger. This caused the error to appear after every update, but the problem has now been fixed.
