Read moreWhat is compute function in flutter?
Dart is a single threaded language, but it comes with a handy compute function to spawn isolates . In a nutshell, the compute function is useful for doing extra work on a different “thread”–it’s actually an isolate–so your flutter app does not experience “jank”. Jank occurs when the UI doesn’t render smoothly.29 Eyl 2019

compute<Q, R> function Q is the type of the message that kicks off the computation . R is the type of the value returned. The callback argument must be a top-level function, not a closure or an instance or static method of a class.
Read moreWhat is Flutter performance?
Flutter aims to provide 60 frames per second (fps) performance, or 120 fps performance on devices capable of 120Hz updates . For 60fps, frames need to render approximately every 16ms. Jank occurs when the UI doesn’t render smoothly.
Read moreDoes flutter use VM?
During debug mode, Flutter uses a virtual machine (VM) to run its code in order to enable stateful hot reload , a feature that lets you make changes to your running code without recompilation.
Read moreCan multiple threads run at the same time?
When multi-threaded program execution occurs on a multiple core system (multiple uP, or multiple multi-core uP) threads can run concurrently , or in parallel as different threads may be split off to separate cores to share the workload. This is one example of parallel processing.
