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.

Maybe this help you
```
Backend backend = Backend.instance();
PackageInfo packageInfo = await PackageInfo.fromPlatform();
String packageName = packageInfo.packageName;

Response r;
try {

  r = await backend.io.get("https://play.google.com/store/apps/details?id=$packageName&hl=en");
  if(r.statusCode == 200){
    String data = r.data;

    String pat1 = 'Current Version
```
'; String pat2 = ''; int p1 = data.indexOf(pat1) + pat1.length; String f = data.substring(p1, data.length); int p2 = f.indexOf(pat2); String currentVersion = f.substring(0, p2); return currentVersion; } return null; } catch (e) { errors = backend.interceptor.errors; return null; }
