Flutter OnScreen Keyboard opens on physical key press #51478
Description
I have a device that uses a laserscanner to scan barcodes and outputs the result as simulated keypresses. I've used this with a RawKeyboardListener and it worked fine. Since then I've added a login screen to the app, that is only shown if the user hasn't logged in. If the login screen has been shown and disposed the onscreen keyboard opens when i press the physical scanner button. This should not happen and doesn't happen if the login screen hasn't been shown. My guess is, that there still are some remains of the textfields used in the login screen, after it is disposed. I've tried setting the FocusNodes for the Textfields and then disposing them in the dispose method, but that didn't work
I've asked a question on StackOverflow: https://stackoverflow.com/questions/60417173/flutter-onscreen-keyboard-opens-on-physical-key-press
Steps to Reproduce
- Screen with one or more Textfields
- focus one or more
- navigate to new screen
- press physical button
Expected results: button is pressed but only the keyevents are fired
Actual results: the onscreen keyboard opens
