flutter_updater

This library allows you to easily add auto-update functionality to your Android, iOS, and Windows Flutter application.

Our use case was to update the app by launching the App Store on iOS or install/execute the Android APK or Windows executable; thus, this package was born. To use this package, you should adhere to the format of the Version Template below.

Features

• Fetch updates from iTunes App Store/remote URL
• Launch App Store
• Download functionality with progress
• SHA512 hash checksum on download

Installation

Run the following command

flutter pub add flutter_autoupdate

Import the package

import 'package:flutter_autoupdate/flutter_autoupdate.dart';

Add the following to your Android app.

• AndroidManifest.xml

<!-- Provider -->
<provider
    android:name="androidx.core.content.FileProvider"
    android:authorities="${applicationId}.fileProvider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

• android/app/src/main/res/xml/file_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path path="Android/data/<package name>/" name="files_root" />
    <external-path path="." name="external_storage_root" />
</paths>

Update the <package name> to your app package name

Examples

import 'package:flutter_updater/flutter_autoupdate.dart';

// Android/Windows
var updater = UpdateManager(versionUrl: 'versionUrl');

// iOS
var updater = UpdateManager(appId: 1500009417, countryCode: 'my');

// App Store country code, this flag is optional and only applies to iOS
var result = await updater.fetchUpdates();
print(result?.latestVersion);
print(result?.downloadUrl);
print(result?.releaseNotes);
print(result?.releaseDate);
 
if (result?.latestVersion > Version.parse('1.0.0')) {
  // Get update stream controller
  var update = await result?.initializeUpdate();
  update?.stream.listen((event) async {
    // You can build a download progressbar from the data available here
    print(event.receivedBytes);
    print(event.totalBytes);
    if (event.completed) {
      print('Download completed');

      // Close the stream controller
      await update.close();

      // On Windows, autoExit and exitDelay flag are supported.
      // On iOS, this will attempt to launch the App Store from the appId provided
      // On Android, this will simply attempt to install the downloaded APK
      await result?.runUpdate(event.path, autoExit: true, exitDelay: 5000);
    }
  });
}
