I think the lack of low level threading primitives really holds flutter from replacing native code for everything except interfacing with system interfaces.
The inability to write high performance multi threaded code means we all ways have to fall back to other languages for these kinds of tasks.

Which is the best structure to follow while coding in flutter.
I know I'm late. Sorry.
Any help is appreciated.

23:00 I strongly disagree with a statement about measure first and then optimize for this case. Let me explain. Bad code can run fast if you have great hardware and a framework, but it is bad code. Bad code in this context includes also a bad programming approach or architectural decision. So my recommendation will be to apply framework best practices and platform specifics for the code. In the context of the question, it means USE Isolates. "Measure first" approach will postpone the problem and will create technical debt.

I'll love to see some real Flutter / Dart project running on Raspberry PI. Start a simple terminal and launch a full graphical app, with keyboard and mouse support, it will open the door for many IoT graphical projects.
