About #

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.

app_namethe name of the app
new_app_versionthe new app version
new_app_codethe new app code
android_packageandroid app package name
ios_packageios bundle identify
windows_packageandroid app package name
linux_packageios bundle identify
macos_packageandroid app package name
web_packageios bundle identify

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

        jsonUrl: '',
        onPressDecline: () {},
        onPressConfirm: () {},
