ota_update

pub package

Flutter plugin implementing OTA update.
On Android it downloads the file (with progress reporting) and triggers app installation intent.
On iOS it opens safari with specified ipa url. (not yet functioning)

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 
  // START LISTENING FOR DOWNLOAD PROGRESS REPORTING EVENTS
  try {
    //LINK CONTAINS APK OF FLUTTER HELLO WORLD FROM FLUTTER SDK EXAMPLES
    //destinationFileName is optional
    OtaUpdate().execute('https://internal1.4q.sk/flutter_hello_world.apk', destinationFilename: 'flutter_hello_world.apk').listen(
      (OtaEvent event) {
        print('EVENT: ${event.status} : ${event.value}');
      },
    );
  } 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
