My flutter application is a bit slow when booting, so I need to know what is happening during the startup. More specifically, I want to use the Performance and CPU Profiler tabs of Flutter DevTools.
However, to use those DevTools, I need to open the DevTools page, click "record", and then click "start recording" / "refresh". However, I am not quick enough (and IMHO it is also not a good idea) to quickly do these steps when the app is starting up, in order to capture information about startup.
Thus I wonder what I should do? Thanks!
P.S. This does not work, because that does not talk about CPU profiling. This also does not work, because it is not a "real" restart and many states are not re-inited, etc.
P.S. A sample screenshot of Performance and CPU Profiler tab:
