AppCheck

Pub

A Flutter plugin that allows you to check if an app is installed/enabled, launch an app and get the list of installed apps.

Installation

First, add appcheck as a dependency in your pubspec.yaml file.

Methods available

• checkAvailability(String uri)
• isAppInstalled(String uri)
• getInstalledApps() (only for Android)
• isAppEnabled(String uri) (only for Android)
• launchApp(String uri)

Permissions

Before using the plugin, you need to add declarations in your configuration files.

Android

If you want to use the getInstalledApps() function, you need the QUERY_ALL_PACKAGES permission.

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

If you only want to check certain apps and you know the packageName, add them via queries in AndroidManifest.xml.

<queries>
   <package android:name="com.google.android.apps.maps"/>
</queries>

iOS

Make sure your Info.plist file includes the necessary URL schemes under LSApplicationQueriesSchemes to check and launch other apps:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>scheme1</string>
    <string>scheme2</string>
    <!-- Add more schemes as needed -->
</array>

Example:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fb</string>
    <string>twitter</string>
    <string>instagram</string>
    <string>whatsapp</string>
    <string>youtube</string>
    <string>comgooglemaps</string>
    <string>http</string>
    <string>https</string>
    <string>mailto</string>
    <!-- Add more schemes as needed -->
</array>
