Answer 1

Please check that all required dependencies are included within "dependencies:" in pubspec.yaml. Dependencies declared inside "dev_dependencies:" are not included in released app

Answer 2

Add the following entries into your proguard-rules.pro file. If you don't have this file you can create and put in app folder.
-keep class com.arthenica.mobileffmpeg.Config {
native <methods>;
void log(long, int, byte[]);
void statistics(long, int, float, float, long , int, double, double);
}
-keep class com.arthenica.mobileffmpeg.AbiDetect {
native <methods>;
}
