La aplicación Flutter se abarca en Android 12
I have resolved the issue. Here is what I did:
1. add android:exported="true" in my AndroidManifest.xml to all activities, services, or broadcast receivers that use intent filters
2. add implementation 'androidx.work:work-runtime-ktx:2.7.0' in the dependencies section of my app level build.gradle (android/app/build.gradle)
After that my app was working regularly on Android 12 and these changes did not affect the lower Android versions
