Flutter ffi failed to open dynamic library

Question

I'm trying to use the flutter ffi to port over my c/c++ code but it's unable to open the dynamic library it needs to be able to work(I'm on windows)

import 'dart:ffi';
import 'dart:io' show Directory, Platform;

import 'package:ffi/ffi.dart';
import 'package:path/path.dart' as path;

typedef ValidNative = Bool Function(Pointer<Utf8> name, Pointer<Utf8> password);
typedef valid = bool Function(Pointer<Utf8> name, Pointer<Utf8> password);

void main() {
  // Open the dynamic library
  var libraryPath = path.join(Directory.current.path, 'src', 'ye.so');
  if (Platform.isMacOS) {
    libraryPath = path.join(Directory.current.path, 'src', 'ye.dylib');
  }
  if (Platform.isWindows) {
    libraryPath = path.join(Directory.current.path, 'src', 'dll');
  }
  final dylib = DynamicLibrary.open(libraryPath);
  final valid Valid = dylib.lookupFunction<ValidNative, valid>('valid');

  var thi = Valid('Admin'.toNativeUtf8(), 'password'.toNativeUtf8());
}

does anyone know how I could fix this and get it to open the library(in my case the DLL file)? Any help would be appreciated!
