I'm using sms_maintained in my application, and when sending message method is called, it prompts for the permission and as soon as we allow; the app crashes with this error in console.

I found, many other developers are having same issue for sms and camera permissions.
Q. Is there any fix available?

Answer 1

The plugin sms_maintained in contrast to its name, seems to be no longer being updated. As for the error that you're getting, it seems to be an Android permission issue caused by the plugin that you're using. Since the plugin is no longer maintained, you may want to consider migrating to a more up-to-date sms plugin like flutter_sms.
