Getting Started

1. Use Plugin:

  • add this code in pubspec.yaml
  r_upgrade: last version

2. Upgrade from your website ( Android or IOS )

    void upgradeFromUrl()async{
        bool isSuccess =await RUpgrade.upgradeFromUrl(

Android Platform

1.Get android store list.

    void getAndroidStores() async {
       final stores = await RUpgrade.androidStores;

2.Get version from android store.

    void getVersionName() async {
       final versionName = await RUpgrade.getVersionFromAndroidStore(AndroidStore.GOOGLE_PLAY);

3. App upgrade from store.

    void upgradeFromAndroidStore(){
       bool isSuccess = await RUpgrade.upgradeFromAndroidStore(AndroidStore.GOOGLE_PLAY);
       print('${isSuccess?'jump success':'jump error'}');

make sure your application had this permission and request dynamic permission.

    <!--(if you want to upload google store,can not add this permission)-->
    <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
     <!--(if you want to use silent install,need to add this permission,and app is system app-->
    <uses-permission android:name="android.permission.INSTALL_PACKAGES" tools:ignore="ProtectedPermissions"/>

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

1. Add Upgrade Download Listener

RUpgrade.stream.listen((DownloadInfo info){


param desc
(int) id download id
(int) max_length download max bytes length (bytes)
(int) current_length download current bytes length (bytes)
(double) percent download percent 0-100
(double) planTime download plan time /s (X.toStringAsFixed(0))
(String) path download file path
(double) speed download speed kb/s
(DownloadStatus) status download status

2. Upgrade your application

This upgrade have two part. useDownloadManager:

  • true: Use system DownloadManagerto download
    • advantage:Simple, use system.
    • Inferiority:can not use http download , can not click the notification pause downloading, can not pause and continue download by network status etc...
    • support: RUpgrade.streaminstallcancel
  • false: Use Service download(default use)
    • advantage:Power, support http/https download, support auto pause and continue download by network status etc..
    • Inferiority:No bugs found yet. If you find a bug, you are welcome to issue
    • support: RUpgrade.streaminstallcancel
      // [installType] downloaded finish will use install type to install apk.
      // [apkName] apk name (such as `release.apk`)
      // [notificationVisibility] notification visibility.
      // [notificationStyle] download notification show style about content text, only support [useDownloadManager]==false.
      // [useDownloadManager] if true will use DownloadManager,false will use my service ,
      //         if true will no use [pause] , [upgradeWithId] , [getDownloadStatus] , [getLastUpgradedId] methods.
      // [upgradeFlavor] you can use [RUpgradeFlavor.normal] , [RUpgradeFlavor.hotUpgrade] , [RUpgradeFlavor.incrementUpgrade] flavor
      void upgrade() async {
      int id = await RUpgrade.upgrade(
                 apkName: 'app-release.apk', installType: RUpgradeInstallType.normal,);
      New upgraded flavor:(no support use DownloadManager)
      enum RUpgradeFlavor {
      normal, // full upgrade
      hotUpgrade, // hot upgrade
      incrementUpgrade, // increment upgrade

3. Cancel Download

    void cancel() async {
      bool isSuccess=await RUpgrade.cancel(id);

4. Install Apk

  • use download id install
      void install() async {
        bool isSuccess=await RUpgrade.install(id);
  • use file path install
      void installByPath(String path) async {
        bool isSuccess=await RUpgrade.installByPath(path);
  • install type
    /// [RUpgrade.upgradeWithId]、[RUpgrade.upgrade]、[RUpgrade.install]、[RUpgrade.installByPath]
    enum RUpgradeInstallType {
    normal,//normal install
    silent,//silent install
    none,// not install

5. Pause Download

    void pause() async {
      bool isSuccess=await RUpgrade.pause(id);

6. Continue Download

    void pause() async {
      bool isSuccess=await RUpgrade.upgradeWithId(id);
      /// return true.
      /// * if download status is [STATUS_PAUSED] or [STATUS_FAILED] or [STATUS_CANCEL], will restart running.
      /// * if download status is [STATUS_RUNNING] or [STATUS_PENDING], nothing happened.
      /// * if download status is [STATUS_SUCCESSFUL] , will install apk.
      /// return false.
      /// * if not found the id , will return [false].

7. Get the last upgrade id

    void getLastUpgradeId() async {
     int id = await RUpgrade.getLastUpgradedId();

8. Get the download status from id

    void getDownloadStatus()async{
    DownloadStatus status = await RUpgrade.getDownloadStatus(id);

9. Increment Upgrade

  • 1.Download bsdiff to local.
  • 2.Prepare two installation packages, one is the one to be upgraded( old.apk ), an installation package that you need to update( new.apk )
  • 3.Switch to the 'bsdiff' directory downloaded above on the command line, and run the command./bsdiff old.apk new.apk increment.patch
  • 4.Put theincrement.patchUpload to server
  • 5.use RUpgrade.upgrade(...,upgradeFlavor:RUpgradeFlavor.incrementUpgrade)download file
  • 6.use RUpgrade.install(id) install apk.

The code is as follows:

    int id;
    void incrementUpgrade(){
        id = await RUpgrade.upgrade(
                fileName: 'r_upgrade.patch',
                useDownloadManager: false,
                installType: RUpgradeInstallType.none,
                upgradeFlavor: RUpgradeFlavor.incrementUpgrade,

    void install(){
        try {
            await RUpgrade.install(id);
        } catch (e) {
                .showSnackBar(SnackBar(content: Text('failure!')));

10. Hot Upgrade

  • you can use this id to hot upgrade,but download file is zip. include three file [isolate_snapshot_data]、[kernel_blob.bin]、[vm_snapshot_data].Your can use flutter build bundle generate.

    flutter build bundle
  • generate file path form ./build/flutter_assets and packaged into zip.

|- AssetManifest.json
|- FontManifest.json
|- fonts
    |- ...
|- isolate_snapshot_data *
|- kernel-blob.bin       *
|- packages
    |- ...
|- vm_snapshot_data      *
  • use RUpgrade.upgrade(...,upgradeFlavor:RUpgradeFlavor.hotUpgrade)download file.
  • download complete you can use download id to hot upgrade
          bool isSuccess = await RUpgrade.install(id);
           if (isSuccess) {
                    .showSnackBar(SnackBar(content: Text('Hot update succeeded, exit the application after 3S, please enter again')));
                Future.delayed(Duration(seconds: 3)).then((_){
                  SystemNavigator.pop(animated: true);
                    .showSnackBar(SnackBar(content: Text('Hot update failed, please wait for update package download to complete')));

At present, the hot update is still in the testing stage, only supporting the change of the flutter code, not supporting the resource file, etc. the author of the plug-in is not responsible for all the consequences caused by the hot update, and the user is responsible for it.

Android Platform Notification Bar

If you want to customize the content displayed in the download notification bar, you can do so, modify or add files project/android/app/main/res/values/r_upgrade_value.xml,add the following code

<?xml version="1.0" encoding="utf-8"?>
    <string name="r_upgrade_download_speech">%.0f kb/s</string>
    <string name="r_upgrade_download_planTime">%.0fs left</string>
    <string name="r_upgrade_download_finish">Download finished</string>
    <string name="r_upgrade_download_paused">Download paused</string>
    <string name="r_upgrade_download_failed">Download failed</string>

And then.When you use upgrade method,you should set the notificationStyle param.

/// Notification show style about content text
enum NotificationStyle {
  speechAndPlanTime, // 100kb/s 1s left
  planTimeAndSpeech, // 1s left 100kb/s
  speech,// 100kb/s
  planTime, // 1s left
  none, //

IOS Platform

1.Go to the AppStore Upgrade

    void upgradeFromAppStore() async {
        bool isSuccess =await RUpgrade.upgradeFromAppStore(
                 'your AppId',//such as:WeChat AppId:414478124

2.Get the last version form AppStore

    void getVersionFromAppStore() async {
        String versionName = await RUpgrade.getVersionFromAppStore(
                'your AppId',//such as:WeChat AppId:414478124
