# AppCheck
|
|
|
|
[](https://pub.dartlang.org/packages/appcheck)
|
|
|
|
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](https://flutter.io/using-packages/).
|
|
|
|
## 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.
|
|
|
|
```xml
|
|
<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.
|
|
|
|
```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:
|
|
|
|
```xml
|
|
<key>LSApplicationQueriesSchemes</key>
|
|
<array>
|
|
<string>scheme1</string>
|
|
<string>scheme2</string>
|
|
<!-- Add more schemes as needed -->
|
|
</array>
|
|
```
|
|
|
|
Example:
|
|
|
|
```xml
|
|
<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>
|
|
```
|
