Deploy your Flutter Android app on the Google Play Store

Let's see how to deploy your Android app on the Google Play Store.

Generate a key sign your Android app

You must first generate a key to sign your Android app. This key will be used to sign all your future versions of your app.

Don't lose it, otherwise you won't be able to update your app anymore.

keytool -genkey -v -keystore ~/my-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my-key-alias

Create a file

Create a file named in the android folder of your project.


Of course you must replace the values with your own... For security reasons, it is recommended to use environment variables to store your passwords. Store your key in a safe place, as you will need it to update your app. Never put this in a public repository.

Your android folder should look like this: Capture d’écran 2023-03-14 à 09.56.46.png

Configure your app

Open the android/app/build.gradle file and add the following lines:

// [...]

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('')
if (keystorePropertiesFile.exists()) {
   keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

android {
 // [...]

	signingConfigs {
      release {
         keyAlias keystoreProperties['keyAlias']
         keyPassword keystoreProperties['keyPassword']
         storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
         storePassword keystoreProperties['storePassword']
	buildTypes {
      release {
				signingConfig signingConfigs.release

// [...]

Generate the Executable file

Run this command to generate the AppBundle file:

flutter build appbundle --release \
--dart-define=BACKEND_URL= \

If you have setup flavors, you can run this command

flutter build appbundle --release --flavor <flavor_name> \
--dart-define=BACKEND_URL= \

Don't forget to add all your environment variables. That's one of the reasons I encourage you to use a CI to build your app.

AppBundle are like Zip files containing all the resources of your app. It is the format required by the Google Play Store to be able to deploy your app. You can also build an APK directly to test your app on your phone.

But don't send an APK to the Google Play Store. Send an AppBundle instead.

Create a Google Play Store account

You must have a Google Play Store account to be able to deploy your app. To create an account, go to the following link: Google Play Console

Create a new application

Once your account is created, you can create a new application. Now you can fill in the information about your app and drag and drop the AppBundle file you generated earlier into a production or test release.

Pushing an update

You must increment the version number of your app in the pubspec.yaml file. Then you can generate a new AppBundle file and upload it to the Google Play Store.

like this

version: 1.0.0+1
version: 1.0.1+2

Then you can run the build command again

ℹ️ Note: Flutter encourage you to use the Semantic Versioning to manage your app version.

ℹ️ Note2: The google play store only care about the +1 number. The 1.0.0 is only for you. But it's a good practice to use the semantic versioning.
