  try {
      //LINK CONTAINS APK OF FLUTTER HELLO WORLD FROM FLUTTER SDK EXAMPLES

        destinationFilename: 'flutter_hello_world.apk',
        //OPTIONAL, ANDROID ONLY - ABILITY TO VALIDATE CHECKSUM OF FILE:
        sha256checksum: "d6da28451a1e15cf7a75f2c3f151befad3b80ad0bb232ab15c20897e54f21478",
      ).listen(
        (OtaEvent event) {
          setState(() => currentEvent = event);
        },
      );
  } catch (e) {
      print('Failed to make OTA update. Details: $e');

Android #

Add following provider referrence to AndroidManifest.xml inside <application> node.

<provider
    android:name="sk.fourq.otaupdate.OtaUpdateFileProvider"
    android:authorities="${applicationId}.ota_update_provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/filepaths" />
</provider>

See AndroidManifest.xml in example

Also, create the file android/src/main/res/xml/filepaths.xml with following contents. This will allow plugin to access the downloads folder to start the update.

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_download" path="Download"/>
</paths>

See filepaths.xml in example
