Different deeplinking url between onGenerateInitialRoutes and onGenerateRoute #161867
Description
Steps to reproduce
- Run the code sample
- Run this command to test deeplink.
adb shell 'am start -a android.intent.action.VIEW \
-c android.intent.category.BROWSABLE \
-d "https://example.com/test"' \
com.example.test- Note the printed value of
onGenerateRoutemethod - Stop the app
- Run
flutter logs - Run this command again
adb shell 'am start -a android.intent.action.VIEW \
-c android.intent.category.BROWSABLE \
-d "https://example.com/test"' \
com.example.test- Note the printed value by
onGenerateInitialRoutesmethod
Expected results
The two printed values should be the same
Actual results
The two values are different. onGenerateInitialRoutes keeps all the url https://example.com/test while onGenerateRoute keeps only the path /test.

Please check the behavior described for https://api.flutter.dev/flutter/material/MaterialApp/onGenerateRoute.html to see if it helps further in your case as why it could be different behavior.

@darshankawar
It doesn't explain the different behavior. I think that
initialRouteshould only be the path without the scheme and the base url or else mention in the documentation that there is this different behavior when using a deeplink.darshankawar commentedon Jan 21, 2025
Thanks for the update. I do see the same behavior upon following the details as provided.

@chunhtai I think this is expected behavior. Can you confirm?
