On Android it downloads the file (with progress reporting) and triggers app installation intent.
On iOS it opens safari with specified ipa url. (only briefly tested)

Usage

To use this plugin, add ota_update as a dependency in your pubspec.yaml file.

Example

// IMPORT PACKAGE
import 'package:ota_update/ota_update.dart';

// RUN OTA UPDATE 
try {
  // START LISTENING FOR DOWNLOAD PROGRESS REPORTING EVENTS
  try {
    //LINK CONTAINS APK OF FLUTTER HELLO WORLD FROM FLUTTER SDK EXAMPLES
    OtaUpdate().execute('https://test1.4q.sk/flutter_hello_world.apk').listen(
      (OtaEvent event) {
        print('EVENT: ${event.status} : ${event.value}');
      },
    );
  } catch (e) {
    print('Failed to make OTA update. Details: $e');
  }
