Bug: QR Code Shows Last Stored Data Instead of Handling Empty Input Properly

[Devmoni]

Description:

In the QR Code activity, when the username is cleared and "Go" is pressed, the generated QR code displays the last stored data from the database.

Expected Behavior:

I think it should either prompt the user with "Enter valid text" or display a blank QR code when the input is empty.

Steps to Reproduce:

Enter a username and generate a QR.
Clear the username field.
Press "Go."

Current Behavior:

QR shows the last stored data from the database.

When the field is empty, it generate an empty QR Code it's not wrong.

Apologies for the confusion during my testing. It was displaying the last saved output earlier.
However, we could also consider prompting the user to enter some text for QR generation. This might be helpful, especially for younger children.
Thanks...
