How to Publish App On Play Store

This section will help you to learn how to publish app on play store step by step.

Requirements

Before publishing android app to google play store make sure you have the following requirements.

• App Logo (512x512px)
• App Banner (1024x500px)
• Screenshots for mobile, tablet, and Chromebook (1920x1024px, 16:9 ratio)
• App signing key (key.jks and key.properties)
• App Name and Description
• Privacy Policy
• About Us
• App Video (optional)
• App Bundle
• Verified Google Play Console Account

Step 1: Generate App Icon

• Generate Icon from App Icon Generator
• Paste the generated icon in android/app/src/main/res folder.

Step 2: Create KeyStore File

You can paste the following command in the terminal to generate keystore file.

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

• Enter the password and other details.
• You will get upload-keystore.jks file in your home directory.

In my case location is

C:/Users/iambi/upload-keystore.jks

Step 3: Create Key Properties File

Create a file named key.properties in the android folder and paste the following code.

storePassword=<password-from-previous-step>
keyPassword=<password-from-previous-step>
keyAlias=upload
storeFile=<keystore-file-location>

Step 4: Update Build Gradle File

Now open the android/app/build.gradle file and paste the following code.

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

android {
         ...
}

Also, update the signingConfigs and buildTypes section.

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

Step 5: Change App Name

Open the android/app/src/main/AndroidManifest.xml file and change the android:label value.

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <application
        android:label="Your App Name"
        android:icon="@mipmap/ic_launcher">

Step 6: Change App ID

Open the android/app/build.gradle file and change the applicationId value.

defaultConfig {
    applicationId "com.example.app"
    ...
}

Step 7: Build Signed App Bundle on VS Code:

flutter build appbundle

-Alternatively,you Use Android Studio to build a signed app bundle.

Step 8: Publish and Release for Google Review

• Fill the necessary details under section of “Set up your app”.

• Goto Create and Publish a Release(app bundle ) and Submit the release for Google’s review.

• After Google’s review, if no issues are found, your app will be ready for publishing.
