Setup environment for keytool:
- Run this command in your system terminal: flutter doctor -v
- Find the Java binary at: copy this path except the “java” folder.
- Change your terminal path by running this command : cd “past here your copied path” then press enter. Example: cd C:\Program Files\Android\Android Studio\jre\bin
- Run the keytool.exe file. Example: C:\Program Files\Android\Android Studio\jre\bin>keytool.exe
Create jks file for uploading app on playstore:
- Open your project path and run this command: keytool -genkey -v -keystore android/app/key.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias key
- Provide all information.
Your created JKS file is located your project->android->app folder
** If you lose the jks file , you will not be able to release a new update your app in playstore**
Create new file key.properties in the android folder . Enter the information

in app/build.gradle do necessary changes
Note: You may need to run flutter clean after changing the gr0adle file. This prevents cached builds from affecting the signing process.
Now you are almost done
In your terminal run: flutter build appbundle
The release bundle for your app is created at <your app dir>/build/app/outputs/bundle/release/app.aab.
Upload this app.aab file to your google play console
