Intercom push notification freezes/recalls main() when enters foreground in Android flutter (Conflicts with branch.io)
Description In our flutter application, on the android platform when we try to tap on the intercom push notification while the app being in killed or in background, it just opens the app and freezes the screen on splash(in killed state) or freezes current screen(incase was in background) This happens only when there is this package i.e: branch.io initialized in main().
Note: this happens only on the android, while on iOS we do not face this issue.

@pankaj-goa It may be an issue with Branch SDK.
What is your MainActivity launchMode in AndroidManifest? By default, it is "standard".
In the configure app section on branch docs, they are using "singleTask" launch mode. Maybe you can try that.
For various launch modes, you can read here https://developer.android.com/guide/topics/manifest/activity-element#lmode
@deepak786 I confirm launchMode was set to "singleTask" and configured properly as per branch SDK documentation.
