Flutter : path-related methods not work on iOS simulator inside a macOS VM

Question

I'm using OSX-KVM to run a macOS VM on Fedora, and run an iPhone 14 Pro Max simulator inside it.

Error:

[VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)

<asynchronous suspension>

the flutter_wpp/db/wpp_db.g.dart is generated by floor and works fine on Android.

Here is flutter_wpp/db/db_manager.dart:

import 'package:floor/floor.dart';

import 'wpp_db.dart';

class DbManager {
  static WppDb? database;

  static setDb() async {
    database = await $FloorWppDb
        .databaseBuilder('app_database.db')
        .addMigrations([]).build();
  }

  static WppDb get db => database!;
}

Here is flutter_wpp/entity/app_dir.dart:

import 'dart:io';

import 'package:path_provider/path_provider.dart';

class AppDir {
  static Directory data = Directory('');
  static Directory cache = Directory('');

  static setDir() async {
    data = await getApplicationDocumentsDirectory();
    cache = await getTemporaryDirectory();
  }
}

Both getDatabasePath and getApplicationDocumentsDirectory are supposed to work on iOS. I have no idea why those errors happen.
