How to get redirected url in flutter which open app?

Question

I define host URL in my Flutter app

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data
        android:scheme="https"
        android:host="example.io" />
</intent-filter>

example.io is my base URL when I click any URL with this base it open my app how I can get

https://example.io/uniqueid
https://example.io/

When I tap on either above URL, it opens my app. How I can get uniqueId every-time when app is launched with my URL?
