Steps to reproduce
- Create a Flutter app using go_router.
- Configure AndroidManifest.xml with an to handle https deep links (e.g., https://example.com).
- Launch the app from a cold start (app not running) with a deep link that has no explicit path:
adb shell 'am start -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d "https://example.com"' com.example.android_issue_sample
Expected results
- The deep link https://example.com should be normalized to https://example.com/,
preserving the scheme (https) and authority (example.com). - Router should correctly recognize this as a deep link and route accordingly.
Actual results
- The URI is converted to /?, losing the scheme and host.
- go_router treats this as a relative route rather than the full deep link.
- Example log output:
redirect: /?
instead of
redirect: https://example.com/
