Ready to program some Flutter apps? The first steps are an old, familiar refrain. First you get some software. Then you run the software. This is how you get your software set up to start programming Flutter apps.
Hello everyone, today you can finally download Flutter for Mac and get a chance to basically experience the future of programming brought to you by Google themselves. If you ever wanted to easily build native apps for both Android and iOS, this is probably the best software to do it. Segment 3 – Download Flutter & Dart – The Complete Flutter App Development Course's Source code – Get source code for the course projects. Section 4 – Installing Development Tools and Machine Setup Mac computer Users: Set up your MAC COMPUTER to begin developing Flutter Apps. The technical preview for Flutter Web was released, and a live demonstration showed how Flutter apps can run on Desktop environments, like Chrome OS, Linux, Mac OS, or Windows. In this article we.
Getting and installing the stuff you need to program Flutter apps
- Download this file containing all the Flutter program examples from Dummies.com.The downloaded file is a
.zip
archive file.Most web browsers save files to theDownloads
directory on the computer’s hard drive. But your browser may be configured a bit differently. One way or another, make note of the folder containing the downloaded fileFlutterForDummies_Listings.zip
. - Extract the contents of the downloaded file to a place on your computer’s hard drive.
- Visit Flutter’s Install Page and download the Flutter SDK.Choose a version of the software that matches your operating system (Windows, Macintosh, or whatever).
- Extract the contents of the downloaded file to a place on your computer’s hard drive.The aforementioned contents is actually a directory full of stuff. The directory’s name is
flutter
. Put your newflutter
directory in a place that isn’t protected with special privileges. For example, if you try extracting theflutter
directory inside thec:program
files directory, Windows displays its User Account Control dialog box and asks for confirmation. Don’t put theflutter
directory inside a place like that.Many Flutter programmers like to put theflutter
directory inside the home directory. This home directory usually contains aDocuments
directory, aDownloads
directory, and lots of other stuff. After you extract the downloaded file’s content, the home directory should have a brand-newflutter
directory.You don’t have to extract theflutter
directory right inside your home directory, but it’s the simplest, most reliable thing you can do. - Make a note of the place on your hard drive where the new
flutter
directory lives.For example, if you copied the.zip
file’s contents to your/Users/janeqreader
directory, make a note of the/Users/janeqreader/flutter
directory. That’s your Flutter SDK path.To make sure that you’ve extracted the downloaded file’s contents correctly, look inside theflutter
directory for a subdirectory namedbin
. Your mileage may vary, depending on when you download the Flutter SDK. - Download the Android Studio IDE.The download is an
.exe
file, a.dmg
file, or maybe something else. - Install the software that you downloaded in Step 6.During the installation, a dialog box may offer the option of installing an Android virtual device (AVD). If so, accept the option.Android Studio isn’t the only IDE that has features for creating Flutter apps. Some developers prefer Virtual Studio Code (known affectionately as VS Code) which is available for Windows, Macintosh, and Linux. And if you enjoy roughing it, you can do without an IDE and use the command line along with your favorite text editor — Emacs, vi, or Notepad.Learn more about Visual Studio Code.While you’re visiting any software download site, check the requirements for downloading, installing, and running that software. Make sure you have enough memory and an operating system that’s sufficiently up to date.
Programming Flutter on your Mac
If you have a Mac and you want to create iPhone apps, follow these steps:
- Select App Store from the Apple menu.
- In the store’s search field, type Xcode and then press Enter.The App Store’s search finds dozens of apps, but only one has the simple name Xcode.
- Click the Xcode app’s Get button.As a result, the App Store installs Xcode on your computer.
- Launch the Xcode application.The first time you run Xcode, your Mac installs some additional components. If you want your apps to run on Apple devices, you need those additional components.
Configuring Android Studio to program Flutter apps
Android Studio doesn’t come automatically with Flutter support, meaning you have to add Flutter support the first time you run the IDE. Here’s what you do.
- Launch the Android Studio application.The first time you run a fresh, new copy of Android Studio, you see the Welcome screen.
- Select Configure→Plugins on the Welcome screen.You’ll find the Configure drop-down menu in the lower right corner of the Welcome screen.
- Search for a plugin named Flutter. Install that plugin.
If Android Studio offers the option of installing Dart as well, accept the option.After installing the plugin, Android Studio may want to be restarted. Of course, you should restart it. When you do, you see the Welcome screen again. Now the Welcome screen includes the Start a New Flutter Project option.

Flutter bridge to Sign in with Apple.
Supports login via an Apple ID, as well as retrieving credentials saved in the user's keychain.
Supported platforms #
- iOS
- macOS
- Android
Example Usage #
Flow #
Integration #
Integrating Sign in with Apple goes beyond just adding this plugin to your
pubspec.yaml
and using the credential-receiving functions exposed by it.Once you receive the credentials, they need to be verified with Apple's servers (to ensure that they are valid and really concern the mentioned user) and then a new session should be derived from them in your system.
Your server should then daily verify the session with Apple (via a refresh token it obtained on the initial validation), and revoke the session in your system if the authorization has been withdrawn on Apple's side.
Prerequisites #
Before you can start integrating (or even testing) Sign in with Apple you need a paid membership to the Apple Developer Program. Sign in with Apple is one of the restricted services which is not available for free with just an Apple ID (source).
Setup #
Register an App ID
If you don't have one yet, create a new one at https://developer.apple.com/account/resources/identifiers/list/bundleId following these steps:
- Click 'Register an App ID'
- In the wizard select 'App IDs', click 'Continue'
- Set the
Description
andBundle ID
, and select theSign In with Apple
capability- Usually the default setting of 'Enable as a primary App ID' should suffice here. If you ship multiple apps that should all share the same Apple ID credentials for your users, please consult the Apple documentation on how to best set these up.
- Click 'Continue', and then click 'Register' to finish the creation of the App ID
In case you already have an existing App ID that you want to use with Sign in with Apple:
- Open that App ID from the list
- Check the 'Sign in with Apple' capability
- Click 'Save'
If you have change your app's capabilities, you need to fetch the updated provisioning profiles (for example via Xcode) to use the new capabilities.
Create a Service ID
Next go to https://developer.apple.com/account/resources/identifiers/list/serviceId and follow these steps:
- Click 'Register an Services ID'
- Select 'Services IDs', click 'Continue'
- Set your 'Description' and 'Identifier'
- The 'Identifier' will later be referred to as your
clientID
- The 'Identifier' will later be referred to as your
- Click 'Continue' and then 'Register'
Now that the service is created, we have to enable it to be used for Sign in with Apple:
- Select the service from the list of services
- Check the box next to 'Sign in with Apple', then click 'Configure'
- In the
Domains and Subdomains
add the domains of the websites on which you want to use Sign in with Apple, e.g.example.com
. You have to enter at least one domain here, even if you don't intend to use Sign in with Apple on any website. - In the
Return URLs
box add the full return URL you want to use, e.g. https://example.com/callbacks/sign_in_with_apple - Click 'Next' and then 'Done' to close the settings dialog
- Click 'Continue' and then 'Save' to update the service
In order to communicate with Apple's servers to verify the incoming authorization codes from your app clients, you need to create a key at https://developer.apple.com/account/resources/authkeys/list:
- Click 'Create a key'
- Set the 'Key Name' (E.g. 'Sign in with Apple key')
- Check the box next to 'Sign in with Apple', then click 'Configure' on the same row
- Under 'Primary App ID' select the App ID of the app you want to use (either the newly created one or an existing one)
- Click 'Save' to leave the detail view
- Click 'Continue' and then click 'Register'
- Now you'll see a one-time-only screen where you must download the key by clicking the 'Download' button
- Also note the 'Key ID' which will be used later when configuring the server
Now everything is set up on Apple's developer portal and we can start setting up the server.
Server #
The server part is usually integrated into your existing backends, and there are existing packages for most existing programming languages and web frameworks out there.
In order to show how to build a complete example, we set up a example project on Glitch which offers simple and free hosting of a HTTPS-enabled web API, which is exactly what's needed here.
To get started with the Glitch-based example go to the project's page at https://glitch.com/~flutter-sign-in-with-apple-example and click 'Remix this'. Now you have your own copy of the sample server!
Flutter Web Apps
First select the
.env
file in the file browser on the left and put in your credentials (these will not be public, but only shared with invited collaborators).Then click on the 'Share' button next to your avatar in the upper left, select 'Live App' and copy the entry page URL (e.g.
https://some-random-identifier.glitch.me
).Now update the services you created earlier at https://developer.apple.com/account/resources/identifiers/list/serviceId to include the following URL under
Return URLs
: https://[YOUR-PROJECT-NAME].glitch.me/callbacks/sign_in_with_apple
(replacing the name inside the []
).After this is done, you can now proceed to integrate Sign in with Apple into the code of your Flutter app.

Android #
Adding Sign in with Apple to a Flutter app is shown from 2 sides here. First we look into making the example app work with our server-side setup, and then we go over the additional steps required to set up your app from scratch.
To use this plugin on Android, you will need to use the Android V2 Embedding.
You can find out if you are already using the new embedding by looking into your
You can find out if you are already using the new embedding by looking into your

In your

inside <application>
addOn the Sign in with Apple callback on your sever (specified in
WebAuthenticationOptions.redirectUri
), redirect safely back to your Android app using the following URL:The
PARAMETERS FROM CALLBACK BODY
should be filled with the urlencoded body you receive on the endpoint from Apple's server, and the package
parameter should be changed to match your app's package identifier (as published on the Google Play Store). Leave the callback
path and signinwithapple
scheme untouched.Furthermore, when handling the incoming credentials on the client, make sure to only overwrite the current (guest) session of the user once your own server have validated the incoming
code
parameter, such that your app is not susceptible to malicious incoming links (e.g. logging out the current user).iOS #
At this point you should have added the Sign in with Apple capability to either your own app's capabilities or the test application you created to run the example.
In case you don't have
Automatically manage Signing
turned on in Xcode, you will need to recreate and download the updated Provisioning Profiles for your app, so they include the new Sign in with Apple
capability. Then you can download the new certificates and select them in Xcode.In case XCode manages your signing, this step will be done automatically for you. Just make sure the
Sign in with Apple
capability is actived as described in the example below.Flutter App Development Free Download
Additionally this assumes that you have at least one iOS device registered in your developer account for local testing, so you can run the example on a device.

Your App
- First and foremost make sure that your app has the 'Sign in with Apple' capability (
Runner
(file browser side bar) ->Targets
->Runner
->Signing & Capabilities
), as otherwise Sign in with Apple will fail without visual indication (the code will still receive exceptions) - Either integrate the example server as shown above, or build your own backend
- Ensure that the
clientID
used when validating the receivedcode
parameter with Apple's server is dependent on the client: Use the App ID (also called 'Bundle ID' in some places) when using codes from apps running on Apple platforms, and use the service ID when using a code retrieved from a web authentication flow
