为什么在 Flutter 中无法获取 Android 的已安装应用程序列表？

Question

I have been trying out 2 libraries in order to get a list of all the installed apps for Android. The libraries that I use are made for the Flutter framework. When I try to get a list of installed apps, I noticed that only the app that I am working on is being shown in this list and not all the installed apps. How am I able to override this limitation? Is there anyone who experienced the same problem?

These are the libraries that I have tried:

• device_apps & android_intent
• flutter_appavailability

A swift help is much appreciated!

Answer 1

<manifest...>

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

add this permission to query the packages

By using the package https://pub.dev/packages/device_apps you can get list of packages /apps in the device

And you can get list of packages with:

List apps = await DeviceApps.getInstalledApplications();
