Flutter deeplink Enhance | Go Router

Flutter deeplink :

Flutter deeplink, A deeplink point’s to a specific page in website or mobile app rather than opening up the basic home page or initial screen in mobile app.

We have seen few tutorials previously based on deeplink integration in flutter may visit them for getting in depth knowledge on implementation in your flutter app.

These deeplinks are mostly used to redirect users to a specific page within an app, such as a product page or a specific article, bypassing the need to navigate through multiple pages to find the desired content. Deeplinks are commonly used in mobile apps to provide a more seamless user experience and to increase engagement with specific features or content.

<meta-data android:name="flutter_deeplinking_enabled" android:value="true" />
<intent-filter android:autoVerify="true">
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="http" android:host="example.com" />
    <data android:scheme="https" />
</intent-filter>

For testing run this below command in terminal

adb shell 'am start -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d "http://example.com/“’profile com.example.flutter_basics
