It's unfortunate, but when you lose your keystore, or the password to your keystore, your application is orphaned. The only thing you can do is resubmit your app to the market under a new key.

ALWAYS backup up your keystore and write the passwords down in a safe location.

I lost my .keystore file?

Lost keystore password, but let Google Manage Signing Key

Because you've enrolled in Play Signing (i.e. "Manage Signing Key by Google"), then you can contact Google Play developer support and ask them for instructions on how to reset the upload key for your app. This will consist of creating a new keystore and sending them the new certificate (after you have proved your identity).

You will then need to change your signing configuration in your Flutter project to reference the new keystore.

After that, you'll be able to keep uploading updates of your app to the Play Console and your users will keep receiving updates as before.

The keystore you lost is what Google calls "upload key": it's only used to verify that what is uploaded effectively comes from you. But Google has a hold of the app signing key which it uses to re-sign the APK that are served to users.

I lost my Keystore used to sign my apk. Is it possible to reupload in play store?

Yes, you can delete the previous application and re-upload it.
You won't be able to use the same package name though, as it will already be taken by your old app.
Simply re-upload it as you would when you want to publish a new app.

But remember,
you should always keep your keystore and passwords saved!

I lost my key store password, I want to update my app on plays store with same keystore

Sorry, the answer is there's absolutely no way to update your app with your keystore without the password.

You have to unlist your app and build with a new keystore, list a new one. Users will not see the updated app because the listing is now pointing at a different entry.

Please keep your keystore file like your life.

I reset my Keystore password

If you forgot your password, there is no way to fix this. If your application is not published to the playstore, you are free to change the sign-in cert to a new one. Otherwise you will not be able to update your app at playstore, you have to unpublish your current app, change the package name and publish a new one with a different key and package. So always try keep a backup of your cert file and password.

Seems it should work.
"Manage your app signing keys
With Google Play App Signing, you can securely manage your app signing keys for new or existing apps. Keys are stored on the same secure infrastructure Google uses to store its own keys.

If you lose your keystore or think it may be compromised, Google Play App Signing makes it possible to request a reset to your upload key. If you're not enrolled in Google Play App Signing and lose your keystore, you'll need to publish a new app with a new package name."
