Error writing to secure storage: Null check operator used on a null value"

[denislunjski]

Hello,

can you help me with this error. Writing some data in secure storage doesn't work on some web browsers.

I had an issue on android mobile phone in android webview default app and second one was on macOS Mozilla.

On other browsers it works.

"Error writing to secure storage: Null check operator used on a null value"

Also in console I'm seeing this.

"HelpMeWrite::parse(), start", source: (460) 2025-03-12 13:13:33.742 16427-16427 chromium com.sec.android.app.sbrowser I INFO:CONSOLE(354)] "HelpMeWrite::isActiveElementTextArea(), input", source: (354) 2025-03-12 13:13:33.743 16427-16427 chromium com.sec.android.app.sbrowser I INFO:CONSOLE(453)] "HelpMeWrite::findContentNode(), No rules", source: (453) 2025-03-12 13:13:33.743 16427-16427 chromium com.sec.android.app.sbrowser I INFO:CONSOLE(506)] "HelpMeWrite::parse(), success = false, reason = 3", source: (506) 2025-03-12 13:13:43.705 16427-16427 chromium com.sec.android.app.sbrowser I INFO:CONSOLE(460)] "HelpMeWrite::parse(), start", source: (460) 2025-03-12 13:13:43.705 16427-16427 chromium com.sec.android.app.sbrowser I INFO:CONSOLE(354)] "HelpMeWrite::isActiveElementTextArea(), input", source: (354) 2025-03-12 13:13:43.705 16427-16427 chromium com.sec.android.app.sbrowser I INFO:CONSOLE(453)] "HelpMeWrite::findContentNode(), No rules", source: (453) 2025-03-12 13:13:43.705 16427-16427 chromium com.sec.android.app.sbrowser I INFO:CONSOLE(506)] "HelpMeWrite::parse(), success = false, reason = 3", source: (506)

I'm using flutter_secure_storage: ^9.2.4

Can you please help me with this?

Got the same issue. It works OK on Chrome and Firefox in Windows PC, but I got the error while using Chrome in an Android phone. In the same phone, when using Firefox, this issue does not happen but it also doesn't save anything.

Upon further research, I found @this. That was my problem, and running my app with HTTPS did solve the issue. I noticed that this information is present in the github page, but it is not present in the pub.dev package page. I'd suggest adding that info in the pub.dev page, as I think many people will look there for information (as I did).
