Flutter mobile app, clicking an existing and valid physical back button is not working, even though the Cucumber step succeeds

Question

• I am using JDK 1.8_202, appium 2.0.0-beta.46, node v18.12.0

• There is a programmer developed back button (<--) whose className as "android.widget.Button" whose className as "android.widget.Button", but when I try to verify it using search option, I am getting this pop up.

• Programmatically nothing is happening, even though as a CucumberBDD step, it is showing as executed.

• I am executing on locally connected physical device 'Samsung galaxy note 8'

• Why back button tap/click action is not working even when it is executed??

• I open my flutter mobile app. I am at landing page

• Do some navigation forward. Comeback to a dashboard page

• From dashboard page to get back to landing page, there is a back button like (<--), which I manual tap and can get back to landing page, with no problem.

• Programmatically nothing is happening, even though as a CucumberBDD step, it is showing as executed.

• From Appium Inspector I see it's className as "android.widget.Button", but when I try to verify it using search option, I am getting this pop up.

• The same button with the same click() method is working fine in another scenario.

• I am using JDK 1.8_202, appium 2.0.0-beta.46, node v18.12.0

• Does the previous navigation affects the functioning of the button click() action ? It should not be logically.

• Why back button tap/click action is not working even when it is executed??
