### Platforms you faced the error (IOS or Android or both?)
iOS only

### Expected behavior
Builds and runs

### Actual behavior
Fails build with clang error

           === BUILD TARGET Runner OF PROJECT Runner WITH CONFIGURATION Debug ===
           duplicate symbol _GetDirectoryOfType in:
               /Users/jamescollins/Development/Company/app-name/build/ios/Debug-iphonesimulator/flutter_sound/libflutter_sound.a(FlutterSoundPlugin.o)
               /Users/jamescollins/Development/Company/app-name/build/ios/Debug-iphonesimulator/path_provider/libpath_provider.a(PathProviderPlugin.o)
           ld: 1 duplicate symbol for architecture x86_64
           clang: error: linker command failed with exit code 1 (use -v to see invocation)

[ +3 ms] Could not build the application for the simulator.
[ +1 ms] Error launching application on iPhone Xʀ.
```

Tested environment (Emulator? Real Device?)

iOS emulator

Steps to reproduce the behavior

Create a new flutter project
Depend on redux_persist_flutter or any other library using path_provider as a transient dependency.
Build with xCode or directly to simulator.

i also meet this error i try to downgrade to 1.4.8 this and sdk version but don't work with same error
android is ok but ios (real device) dont build because this error

[jabonge]

As a result of my experiment, it seems that the error occurs when the GetDirectoryOfType method name in the flutter sound plug-in file and the method name GetDirectoryOfType in the path_provider package file overlap. I temporarily forked the flutter sound plugin and noticed that it ran without error when I replaced all of the method names with getDirectoryOfType1(othername).
You can fix it in 3 parts of fluttersoundPlugin.m file
