A Flutter plug-in helps to install iOS and Android apps.
It is not uncommon that you may want to ask a user to install another app within your app. What you need to do here is to prepare a set of iOS app ID on App Store, and Android package name.
For example, if you want to lead your customers to install KKBOX, you need to create an app set like:
var app = AppSet(); app.iosAppId = 300915900; app.androidPackageName = 'com.skysoft.kkbox.android';
Then call the plug-in.
On iOS, the plug-in calls SKStoreProductViewController, while it creates an activity to open a "market://" URL on Android.
That's all. Enjoy!
