How put url download only apk signed?

I have a flutter project that at the end of the pipeline sends a message to slack with the signed apk, but using ${BITRISE_PUBLIC_INSTALL_PAGE_URL} sometimes it is the link for the signed app, sometimes it is for the unsigned one. How do I resolve this?

The install page shows artifacts uploaded in the deploy-to-bitrise-io Step.
Your workflow may be generating both a signed an unsigned apk on the same file path and they could overwrite each other. Can you check gradle configuration and bitrise workflow if there are multiple apks generated? If you can share your workflow, maybe we can spot something.

I’m using Flutter Build step to genareted apk, after Android Signed to signed apk. I don’t have grandle in Bitrise step to generate two apk.
