3. Android
build
Preparation
Hardware requirements
● A 64-bit environment is required for Android 2.3.x
(Gingerbread) and higher versions.
● At least 250GB of free disk space to check out the code and an
extra 150 GB to build it.
● At least 16 GB of available RAM is required, but Google
recommends 64 GB.
The build process involves many tools and processes that convert
your project into an Android App Bundle (AAB).
AAB create via .keystore or .jks(java KeyStore). Once created
bundle we need to one play store account. It will cost around $25
lifetime.

4. Sign the apk or
app bundle
How to sign the apk or app bundle created using flutter ?
To publish your app on Play Store, you need to give your app a
digital signature.
step 1 : Create a new keystore file ; if you have an existing
keystore , skip this step
● Run command in your terminal for linux/mac
keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize
2048 -validity 10000 -alias key
● On Windows, use the following command:
keytool -genkey -v -keystore c:/Users/USER_NAME/key.jks -
storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias
key
● Fill in the required info inside the terminal

15. iOS build
Preparation
Xcode system requirements:
https://developer.apple.com/support/xcode/
Image result for ios build The Xcode build system manages the tools
that transform your code and resource files into a finished app.
When you tell Xcode to build your project, the build system analyzes
your files and uses your project settings to assemble the set of tasks
to perform. Apple developer account cost $100 (per year)
Preliminaries
Xcode is required to build and release your app. You must use a
device running macOS to follow this guide.
Before beginning the process of releasing your app, ensure that it
meets Apple’s App Review Guidelines.
In order to publish your app to the App Store, you must first enroll in
the Apple Developer Program. You can read more about the various
membership options in Apple’s Choosing a Membership guide.

16. Register App
Store
Register your app on App Store Connect
Manage your app’s life cycle on App Store Connect (formerly iTunes
Connect). You define your app name and description, add
screenshots, set pricing, and manage releases to the App Store and
TestFlight.
Registering your app involves two steps: registering a unique Bundle
ID, and creating an application record on App Store Connect.
For a detailed overview of App Store Connect, see the App Store
Connect guide.
Page - 16 of 40

17. Register a
Bundle ID
Every iOS application is associated with a Bundle ID, a unique
identifier registered with Apple. To register a Bundle ID for your
app, follow these steps:
1. Open the App IDs page of your developer account.
2. Click + to create a new Bundle ID.
3. Enter an app name, select Explicit App ID, and enter an ID.
4. Select the services your app uses, then click Continue.
5. On the next page, confirm the details and click Register to
register your Bundle ID.

22. Create a
certificate
signing request
https://developer.apple.com/help/account/create
-certificates/create-a-certificate-signing-request/
Keychain Access on your Mac allows you to create a certificate
signing request (CSR). Open keychain in your mac system. And
follow above link step.
Where use this? → Create a New Certificate: Upload a Certificate
Signing Request To manually generate a Certificate, you need a
Certificate Signing Request (CSR) file from your Mac.

23. iOS build
provisioning
profile
What is a provisioning profile & code signing in iOS?
Apple Developer Program membership is required to request,
download, and use signing certificates issued by Apple.
iOS Distribution Certificate (in-house, internal-use apps)
Users will no longer be able to run apps that have been signed with
this certificate. You must distribute a new version of your app that is
signed with a new certificate.
Developer ID Installer Certificate (Mac applications)
If your certificate expires, users can no longer launch installer
packages for your Mac applications that were signed with this
certificate. Previously installed apps will continue to run however
new installations won't be possible until you have re-signed your
installer package with a valid Developer ID Installer certificate. If
your certificate is revoked, users will no longer be able to install
applications that have been signed with this certificate.

24. iOS build
provisioning
profile
Ad-Hoc certificate?
The Ad-Hoc certificate allows you to build your app to run on a
predetermined list of devices. There are a couple big caveats
though: You need the UDID of every device you want the app to run
on. The user needs to install the provisioning profile for the app as
well as the device manually.

For a detailed overview of app signing, see Create, export, and
delete signing certificates.
Create an app bundle
Run flutter build ipa to produce an Xcode build archive (.xcarchive
file) in your project’s build/ios/archive/ directory and an App Store
app bundle (.ipa file) in build/ios/ipa.
Consider adding the --obfuscate and --split-debug-info flags to
obfuscate your Dart code to make it more difficult to reverse
engineer.
If you are not distributing to the App Store, you can optionally
choose a different export method by adding the option --export-
method ad-hoc, --export-method development or --export-method
enterprise.

39. Obfuscating
Dart code
Code obfuscation is the process of modifying an app’s binary to
make it harder for humans to understand. Obfuscation hides
function and class names in your compiled Dart code, making it
difficult for an attacker to reverse engineer your proprietary app.
The following list describes which platforms support the obfuscation
process described in this page:
Android/iOS/macOS (Supported)
Linux/Windows (Not yet supported.)
Web Obfuscation is not supported for web apps, but a web app can
be minified, which is similar. When you build a release version of a
Flutter web app, it is automatically minified. For more information,
see Build and release a web app.
Flutter’s code obfuscation, when supported, works only on a release
build.

Continuous delivery with Flutter (CI-CD)
Follow continuous delivery best practices with Flutter to make sure
your application is delivered to your beta testers and validated on a
frequent basis without resorting to manual workflows.
