Dart Isolates - Flutter compute function - Multithreading in Dart and Flutter

Dart is a fantastic language with an event loop and its own memory allocation. Today I want to talk a little bit more about how Multithreading in Dart and Flutter is possible. Therefore I talk a little bit on how you can create Isolates and how they work internally. Because the boilerplate of the Isolate is heavy I want also to talk about the compute function of Flutter.

If you read this so far, thank you once more. If you like to support us, here are some links that could help me a lot.

Thanks a billion. This is the best explanation of isolates and compute so far.

[キルア-wg]

Quick, understandable and helpful. You and people like you are gifts from the god himself for the humanity. Thanks for the great video!

[Raimkhodzhanov]

Thank You! Very interesting and helpful video! From Russia with love!

[khanisrarahmedalihusain]

I haven't used it yet, but I found there are some cases in my Project where I can use it and I will.

[rutviktak]

Understood how to work with isolates but had to go through it multiple times though worth the time.
Thanx for the amazing video💙

[Mustafa-fjt]

Thank man you are the only one make me understand Isolate❤️

[dilshan]

You have done great job for flutter .
Thanks for your explanations😇☺️

[SEGVeenstra]

One of the more clear explanations, well done!
I haven't used them, yet, I'm kind of looking into them because I think I might need them.
My use case:
I'm creating a Solver for my own puzzle game. It will look for all the possible solutions. For the smaller puzzles, this works in a matter of milliseconds, but when it tries to solve a complex puzzle, it might take seconds, or even minutes.

I feel like that's a good use-case because I can run the solver without blocking the app (as it's currently doing).

[andersonfs]

helpful on an offline-first approach, consuming a queue of offline events that need to be synchronized with the cloud without blocking the UI. Doing that without Isolates led me to frame drops.

[medamine]

very great explanation.
i think you could use your white board to explain complex topic like this with drawing... its very useful.

[shekharmahadik]

Hi sir i like way you explain the topic and i new in flutter and thanks to 🙏

[beginnerscircle]

I have been able to make use use of it in a project I needed to do some background upload.

[sangamkumar]

i am making an application wherein we are using you help me by telling how we can play the video(in pip mode) in while the app is in background.

[LMrc]

my stopwatch app is stop running when a press the back button, i ear the isoltate can be the solution. how can i implement it please?

[MarcS]

Can I get a progress from a compute function?

[thidiyaslimbu]

My application requires reading a lot of images from memory and displaying then in a list.these images are often huge in size so takes a lot of time loading them. Is isolate best for this scenario?

[sammason]

Hi, this video was great and really helped me! I am just having issue with trying to kill the isolate to prevent the completion of a task on a button press? Any help is much appreciated it!

[balkhan]

Can two isolates interact with a single db on device, something like sqflite?

[sanketkoli]

I have an api that takes 8-10 seconds to get response. By the time I want to navigate through app when my function is still running. Which best method can I use? Thanks!

[mikemannox]

With regards to compute - How can I pass it a reference of a method and its args for isolate processing? Thx
