Flutter application crashing after branch change

Question

We changed our branch yesterday and the app isn't running on the new branch. It gives me an error:

Launching lib/main.dart on Redmi Note 9 Pro in debug mode...
/home/aman/snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/permission_handler-8.3.0/android/src/main/java/com/baseflow/permissionhandler/ServiceManager.java:75: warning: [deprecation] queryIntentActivities(Intent,int) in PackageManager has been deprecated
            List<ResolveInfo> callAppsList = pm.queryIntentActivities(callIntent, 0);
                                               ^

I dont think the branch change is any problem in this. I have no idea tho what its saying.

Answer 1

It states that your permission handler is using a deprecated package. If you are using an older version of flutter upgrade the permission handler in pubspec to 9.0.0 or if you are using flutter 3+ use the latest version and try again. As a first try you can change the version of permission handler in pubspec to any

permission_handler: any

And try if it works
