A Flutter plugin for installing app on Android. The plugin supports both install with Android intent and silently install.

Add this to your package's pubspec.yaml file:

dependencies: flutter_app_installer: ^1.0.0

Install with Android Intent

You need to add the provider inside your AndroidManifest.xml application section.

<!-- 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> 

You need to create one android/app/src/main/res/xml/file_paths.xml with the following content.

Please replace the packageName with your app package's name.

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

If your application API level is above 25, please remember to add the permission in AndroidManifest.xml file.

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

Install silently

In order to install the APK silently, your app must be a system application or has root permission on your emulator.

You need to add permissions in AndroidManifest.xml file.

<!-- Install/delete permissions, only granted to system apps --> <uses-permission android:name="android.permission.INSTALL_PACKAGES" /> <uses-permission android:name="android.permission.DELETE_PACKAGES" /> 

Import the package with

import 'package:flutter_app_installer/flutter_app_installer.dart';

Install your apk with Android Intent.

final FlutterAppInstaller flutterAppInstaller = FlutterAppInstaller(); flutterAppInstaller.installApk( filePath: apk_file_full_path_here, );

Install your apk silently.

final FlutterAppInstaller flutterAppInstaller = FlutterAppInstaller(); flutterAppInstaller.installApk( filePath: apk_file_full_path_here, silently: true, );

The installApk function call is changed from static method to non-static method.

Please remember to change the installApk function call in your application.
