integrity with mobile app
I used the api call using flutter, then built the release apk of the app that shows movies but the content is not loading at all in phones
can you please assist with the problem

TMDb does not provide any links to watch movies or series.
It only provides metadata and posters, backdrops, fanarts, etc...
We cannot provide programming support and/or codes for third-party programs or APPs.
Therefore, we have no idea how to help you.
I suggest you look for a Flutter forum.
