From dart the await FlutterContactPicker.pickPhoneContact() method call gets stuck and never return. Also I noticed that the permission is asked as expected.

• also does not work on iQOO (VIVO)

Ok, the issue seems with android:launchMode="singleInstance in my app's android manifest [it is android:launchMode="singleTop" in the example app].

Once I changed to singleTop it started working. Any idea why is that a case? Is it a bug?

[DRSchlaubi]

The stacktrace doesn't show anything related to this package?

[daadu]

Yes

The stacktrace doesn't show anything related to this package?

Yes, released it after some debugging. It has to do with the launchMode set by the activity. for some reason, onActivityResult is not called when app launched with launchMode=singleInstance

[daadu]

onActivityResult is being called with requestCode: 0, resultCode: 0, data: null when android:launchMode="singleInstance" set on these devices.

I have same issue. Can't pick contact, I have put an try catch then it throw an error UserCancelledPickingException: The user hit the back button instead of selecting a contact @DRSchlaubi

Update: After changed android:launchMode="singleInstance" -> android:launchMode="singleTop" it worked
