The application may be doing too much work on its main thread. in flutter

Question

How come I have this message in my Flutter android app? I try with the counter app which is the first app made by flutter team, it shows this message too. Does it need to be fixed? How do we fix it?

I/Choreographer( 5455): Skipped 45 frames!  The application may be doing too much work on its main thread.

There's a lot of factors that may cause frame skipping. It may be dependent on some of these items:

The size of the widget tree to be displayed on the screen.
Speed of the CPU that does computational work, i.e. parsing JSONs at startup.
The speed of the network connection in case of needing some necessary data before the app starts up.
If you're using an emulator or a physical device.

You may also want to consider testing the app on a physical device and see if similar frame skipping occurs. If not, and if you're not doing anything unnecessary on the screen, then this can be safely ignored.
