Check App Version

A plugin that allows you to check the version of the app installed with a hypothetical version of the app published on the PlayStore / AppStore.


The plugin compares two version codes:

  • The code for the app installed on the device.
  • Code for a new version of the app compiled using JSON.

In fact the package acquires the necessary information for the comparison between the two versions, through a JSON file compiled by the user himself.

Example of a JSON file at this link.

app_namethe name of the app
new_app_versionthe new app version
new_app_codethe new app code
app_packageandroid app package name
bundle_id_iosios bundle identify
ios_app_idiOS app id number


Import the Check App Version package

To use the Check App Version package, follow the plugin installation instructions.

Use the package

Add the following import to your Dart code:

import 'package:check_app_version/show_dialog.dart';

We now have the option to use the method ShowDialog(jsonUrl: 'my url').checkVersion(); to check the version and show a message dialog, remember to replace 'my link' with the link that refers to our previously created and customized JSON file

        context: context,
        jsonUrl: '',

Customize the message dialog

In the ShowDialog() method we have many properties to be able to customize massage dialog.
