import 'package:flutter/material.dart';
import 'package:app_local/app_local.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Locales.init(localeNames: ['en', 'ar', 'fa'],localPath: "assets/a/"); // get last saved language
  // remove await async (to get system language as default)
