my AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.perpet1">
<!-- The INTERNET permission is required for development. Specifically,
the Flutter tool needs it to communicate with the running application
to allow setting breakpoints, to provide hot reload, etc.

So, I did flutter_local_notification update.
Then it appeared on the console as follows.
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
There is no flutter doctor issue.
(in Android Studio)
First, I apologize that English is not my main language and it can be awkward because it is also my first time posting questions.
Above is the error on my console window.
I searched all day yesterday but couldn't find a solution. I would be truly grateful if someone helped me. TT
