{FIXED} I found how to fix the problem. I was using the "new_version" package and I changed to "new_version_plus" and the bug is no longer there!

PS: add this: if(status?.localVersion != status?.storeVersion) { newVersion.showUpdateDialog(

Anyone who still faces this issue can try a new package new_version_plus, you can use the same code by just changing the name, it works completely fine.

make sure you are not forgetting to mention "Release Note" while uploading aab to google play console. when NewVersion is unable to find release note it returns null

you are missing the package name as value in androidId key if working on android to let the new Version function check and compare .Below is the Updated code

 void _checkVersion()async{
    final newVersion=NewVersion(
      androidId: "com.snapchat.android",
    );
    final status=await newVersion.getVersionStatus();
    if(status?.canUpdate==true){
      newVersion.showUpdateDialog(
        context: context,
        versionStatus: status!,
        allowDismissal: false,
        dialogTitle: "UPDATE",
        dialogText: "Please update the app from ${status.localVersion} to ${status.storeVersion}",
      );}}
