I'm new to react native, and I've been having some trouble understanding the folder structure of the app which should supposedly be present in the project folder on creation. Basically, when creating the project with npm, I get some starting files (App.js etc.) and a node_modules folder. I've got it up and running with expo, which created the .expo folder as well.
However, when I go to react's official documentation or look into plugins/addons on git they talk several times about an android and an iOS folder in the project root. But they are nowhere to be seen. I then got some hints that I could install and run react-native-upgrade-git, which allegedly would generate these missing folders. But that didn't work either.
So what have I missed? Where are those folders located?
Edit: Here is a screen dump from a Youtube tutorial showing the project structure I'm looking for:

Expo is updated their command to eject,
To eject and use your custom model
npx expo prebuild
This command ejects your Android and ios folder for further updation
To Run on android device
npx expo run:android
To Run on IOS Device
npx expo run:ios
For more detail https://docs.expo.dev/workflow/prebuild/

If you previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:
npm uninstall -g react-native-cli @react-native-community/cli
then create a new project again:
npx react-native init DemoApp

If you created the project with Expo you will have the Expo folder instead of ios and android folders

To add to Funk Soul Ninja's answer after following his directions (thank you! :) ), for those who started with an Expo project:
expo run:ios
did the trick for me.
The command creates the ios folder that contains the project that can be edited and built in Xcode.
I did not do this step, but I believe expo run:android
does exactly the analogous thing for Android; but I would suggest checking out Expo documentation on adding custom native code.

I had to run expo eject
. The story behind why I didn't have the folders is had to downgrade my react-native application because of some broken dependencies and then I got build failures. So I deleted the ios and android folders then ran expo eject
and got all the build issues fixed. Note that I used expo command line via a script in package json so that the versions would match the version my project was using.

This worked for me: Go to Setting and remove both entries "android" and "ios" from "Files:Exclude". Don't forget both environments - User and Workspace.
Removing entries on Workspace:
... same for User:

The simplest way I know
1) Take your app name from your current app.json, let's say the name is "mynativeapp"
2) make a new folder somewhere outside of your current project folder
3) start in it:
react-native init mynativeapp
4) the command above will make android and ios folders internally compatible by name with your project
5) copy android/ios folders into your project folder
Now you can try to start your native project. I checked that for Android:
react-native run-android
enjoy!
P.S. "react": "16.9.0", "react-native": "0.61.4"

One of the points of Expo on top of React Native is that you don't go down to android or ios code. Expo deals with those folders for you, you don't need to interact with them. Is there a reason you need those folders? if so, you will have to eject. Here's the documentation to do so: Ejecting with ExpoKit

I think I am little late but follow this steps if you don't want to read any document.
android and ios folder are not present when react native project is created with expo. so you have to detach expo from your project to create android and ios folder.
first add required package name in app.json file
ios: {
bundleIdentifier: "com.yourcompany.yourappname",
},
android: {
package: "com.yourcompany.yourappname",
}
then run below command in terminal
exp detach
after command is successfully executed you will find android and ios folder

i think if you want to develop app with ReactNative you start follow this : Getting Started use React Native.
If you create project with ReactNative
just write on your terminal like:
react-native init YourProjectName
cd YourProjectName
react-native run-ios //for iOS
I hope my answer helping you to create project with ReactNative. thanks..

You can get to that project structure by running:
npm run eject
However, it removes the app from the Expo framework, which adds a lot of nice benefits and abstraction from the Android/iOS code.
