App not Launching or going to Foreground from Background when click on accept action button ( ONLY ANDROID )

[mrcse]

An issue I've encountered with the package. For a clearer understanding, I have attached the relevant code example.

After testing on multiple Android devices, I've observed that when our application is running in the background and a call notification is received, there's a glitch in its behavior. Upon clicking the "accept" button on the call notification, the code responsible for navigating to the call screen is executed. However, this does not bring the application to the foreground. Instead, the application remains in the background.

To ensure that the issue isn't with the callback function, I verified the 'onAcceptCallback'. It appears to be functioning correctly because when I manually bring the application to the foreground after clicking "accept", I can see that it has already navigated to the call screen.

*NOTE: This issue only on android side on ios it works fine

your case looks very similar to this https://github.com/ConnectyCube/connectycube-flutter-call-kit/issues/111, have you tried this solution https://github.com/ConnectyCube/connectycube-flutter-call-kit/issues/111#issuecomment-1727946091

I added the SYSTEM_ALERT_WINDOW permission and added a popup for the user to accept the app overlay permission and this works Thanks
