A Flutter plugin which helps you to open another app from your app

Getting Started

The package asks you for four parameters out of which two are mandatory.

For opening apps in android

For opening an external app from your app in android, you need provide packageName of the app.

If the plugin finds the app in the device, it will be be launched. But if the the app is not installed in the device then it leads the user to playstore link of the app.

But if you don't want to navigate to playstore if app is not installed then make the openStore property to false.

For opening apps in ios

In Ios, for opening an external app from your app, you need to provide URLscheme of the target app.

To know more about URLScheme refer to this Link

In your deployment target is greater than or equal to 9 then also need to update external app information in infoPlist.

<key>LSApplicationQueriesSchemes</key>
<array>
	<string>pulsesecure</string> // url scheme name of the app
</array>

But like in Android it will not navifate to store(appStore) if app is not found in the device.

For doing so You need to provide the itunes link of the app.

Additional Feature

Apart from opening an external app, this package can also be used to check wheather an app installed in the device or not.

This can done by simply calling following code

await LaunchApp.isAppInstalled(androidPackageName: 'net.pulsesecure.pulsesecure', iosUrlScheme: 'pulsesecure://');

which retuns true and false based on the fact wheather app is installed or not
