When launching a Flutter view in an existing app, as of the latest versions of Flutter, it takes about 4-5 extra seconds before anything is actually rendered on the screen, after seeing logs printed from our route widget's build method.

I think this happens with native Flutter apps as well, seeing they just seem very long to launch (longer than before).

But in our case, we have timed about 4-5 seconds of dead time between the logs from our build method and the view actually rendering.

This was never the case before.

I've noticed this with 1.18.0-dev.3.0 and 1.18.0-11.0.pre.
