That is called Deep Linking
The following from https://flutter.dev/docs/development/ui/navigation/deep-linking
Enable deep linking on Android
Add a metadata tag and intent filter to AndroidManifest.xml inside the <activity> tag with the ".MainActivity" name:
<!-- Deep linking -->
<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="flutterbooksample.com" />
<data android:scheme="https" />
</intent-filter>
Enable deep linking on iOS
Add two new keys to Info.plist in the ios/Runner directory:
<key>FlutterDeepLinkingEnabled</key>
<true/>
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleTypeRole</key>
<string>Editor</string>
<key>CFBundleURLName</key>
<string>flutterbooksample.com</string>
<key>CFBundleURLSchemes</key>
<array>
<string>customscheme</string>
</array>
</dict>
</array>
