Chapter 3 - Isolates - Free Dart Course 💙

Part of Free Dart Course playlist: • Free Dart Course 💙
Isolates are a rarely-visited aspect of Dart which Flutter developers can also take advantage of in order to create smoother UI experienced for their users. Even the documentation for Isolate in Dart's official documentation is lacking some fundamentals of how Isolate works in Dart and how you can use it.
In this chapter we will look at using Isolate in Dart in order to greatly increase the performance of our applications.

You're very welcome and thank you for your support 💙

[@thomasmabika7291]

Nice work.
Can you also cover design patterns and clean architecture in the future?

[@imadrashid9174]

I was going to request Clean Architecture from him too...
It would be really helpful if you make a playlist on it too.

Great content. Thank you

[@VandadNP]

You’re most welcome brother

[@user-uq7zx5nc3t]

Very nice. Much appreciated.
For flutter web, I must create workers instead of isolates.
Does this mean I have to use JS, or is there a dart way ?
I realise JS and dart are very similar, but I'd rather stick to dart...

[@DemsDema]

Great video. Is there a way to pass an argument to the isolate function together with SendPort?

[@mokshmahajan6340]

You can create a class which will be having sendPort as one of its instance variables and other data that you need to pass.
As the isolate's main function can have only one argument, so you can use this approach to pass multiple data points to your isolate's main function.

[@stephendoyle2658]

Thanks for the video. At 1:10:31 why not just spawn your isolate, and then return rp.takeWhile((e) => e is Iterable).cast(); ? The result would be the same would it not?

[@benny-shen]

what's the difference between using async directly and using isolates?

[@Sergey-fc8gv]

I believe the difference is that using `async` doesn't make your code run in a separate event loop, and can potentially freeze UI.

[@LMrc534]

and if I want to use several functions in a chrono for example Start() stop() and reset() , must I use another isolate?

[@VandadNP]

No need to do that. You won't even need an isolate to do a stop watch tbh

[@LMrc534]

could isolate can avoid my stopwatch being killed when I press the back button?

[@VandadNP]

You don't necessarily need an isolate to create a stop watch
