patchkite

Flutter SDK for Patchkite: self-hosted over-the-air updates for your Dart code.

Patchkite replaces your app's compiled Dart code (libapp.so) with a newer version downloaded from your own server, so you can ship fixes without a store release.

• Android only. Apple doesn't allow loading new native code, so on iOS the plugin is a no-op that always reports "up to date" — you can keep one codebase.
• Diff updates and binary patches; automatic rollback; code signing.
• Updates only reach binaries built with the same Flutter engine revision.

Install

flutter pub add patchkite

Setup

android/app/src/main/kotlin/.../MainActivity.kt:

import io.github.patchkite.flutter.PatchkiteFlutterActivity

class MainActivity : PatchkiteFlutterActivity()   // or PatchkiteFlutterFragmentActivity

android/app/src/main/AndroidManifest.xml, inside <application>:

<meta-data android:name="PatchkiteServerUrl" android:value="https://patchkite.example.com" />
<meta-data android:name="PatchkiteDeploymentKey" android:value="DEPLOYMENT_KEY" />

Dart:

import 'package:patchkite/patchkite.dart';

void main() => runApp(const PatchkiteApp(
      checkFrequency: CheckFrequency.onAppResume,
      child: MyApp(),
    ));

Release updates with the Patchkite CLI, using the same Flutter version as your store build:

patchkite release-flutter MyApp-Android android

Read the Flutter guide for limitations, deployment keys per flavor, code signing, and verification, and the API reference for everything else.

Make sure your use complies with Google Play's policy on downloading executable code.
