This section will help you if you are here for the update and  have already generated the signed release  apk/appbundle the last time and already have the keytool and the manifest file ready in your old project folder.

If you are installing and building the release file for the first time this section is not for you.

Extract the scource_code.zip. You will find this inside the main zip.

Open the folder in your android studio.

**Remember to open this in a separate folder than your old project.

Even if you are building an app for ios, use android studio for the build.

Then in your android studio terminal run:
flutter pub get

This will fetch all the necessary packages

If you are updating, you must have build the key.jks previously

Copy the key.jks , key.properties, and the manifest file from your old project and paste in the correct locations

See the previous screenshots for the file locations

If you are missing your old project, you have to configure key.properties, and the manifest file like described in the installation.

As our source code  is made ready for the fresh installation , you will have to do all your configuration (like domain path, app color, package name etc ) shown in the previous steps.

But do not create a new key.jks, you have to update your app with the existing key

If you have somehow lost your previous key , you have to release a totally  new app to the play store.You will not be able to release an update.

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.
