How can I make my Flutter app run faster?

Instead of threads, all Dart code runs inside of isolates . … Isolates are like threads or processes, but each isolate has its own memory and a single thread running an event loop.

Threading is an implementation of the cooperative, non-preemptive multitasking (software threads) . Also can be used in conjunction with any third-party libraries for parallel computations (for the coordination and synchronization).

An isolate is a thread that has an event loop that continuously processes events in its own memory space .

Flutter/Dart is not technically single-threaded, even though Dart code is executed in a single thread. Dart is a thread-safe-by-default , parallel-capable, totally-non-blocking language with message passing pattern, that can take full advantage of modern multi-core architecture, without worrying about lock or mutex.

Flutter applications aren’t as necessary as a single step by step line of executing code. You have user clicks, timers, keyboard input, and that’s just the beginning, all wanting to method code. On the off chance that there is only simply one thread , at that factor, then how do these events and code get processed?
