Flutter automatically update application when new version is available

Question

How can I implement auto-updating of my application when a new version is released without using Google Play Store? I\'m using JSON to check the version.

Answer 1

My way of implementation is to use a variable and compare that variable from a database. It could be Firebase or any other. For this example, I will use Firebase realtime database.

int version = 1;
void checkLatestVersion(){
    
//Here i am getting just the value of the latest version stored on firebase.    
databaseReference.child("version").child("latestRealase").once().then((snapshot){
      if(snapshot.value != null){
          int versionNumberFromDatabase = int.parse(snapshot.value));
          if(versionNumberFromDatabase>version){
             print("the app needs to be updated");
             //HERE you can create a dialog to display and force users to update
          }else{
             print("The app doesn't to be need updated ");
          }
      }
     });
 }

The above example will work for both Android and iOS, but there is a package that will let you update your app from the app itself. Check the documentation.

in_app_update 1.1.7

This will enables In-App Updates on Android using the official Android APIs.
