App Install Checker plugin for Flutter

A Flutter plugin for checking an app is installed or not on the device.

Getting Started

First, you need to add app_install_checker in your pubspec.yaml file:

import 'package:app_install_checker/app_install_checker.dart';

Only for iOS

For the app performing the installation check Add the iOS scheme in the Info.plist file:

<dict>
    ...
	<key>LSApplicationQueriesSchemes</key>
	<array>
    	<string>example</string>
	</array>
    ...
</dict>

For the app being checked for installation on the device

You don't need to install this package for the app that is checked for installation on the device; you just need to set up the custom URL scheme in the Info.plist file:

<dict>
	...
    <key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>example</string>
            </array>
        </dict>
        ...
    </array>
</dict>
