My app made by android and flutter,

Kotlin coroutines working on complex calculations and networking in android

But,I love dart-lang

So I'm considering switching from coroutines to isolates.

Is there any concern about this?

CodePudding user response：

There are no general concerns that I'm aware of. Although there are some points that you need to consider before doing the change.

• The concurrency paradigm changes from multithread to single thread. This means that you should not think of changing coroutines to isolates, since you will not be using isolates so often or for the same purposes as coroutines.
• Isolates are used for "extreme/unique" cases, if you want to perform a long running operation, you normally shouldn't opt out for an isolate, you should perform that with the simple async/await.
• It's simpler to use async/await since you don't have to worry about resource allocations or race conditions, but at the same time it allows you to do "dirtier" things, to the responsability is on you.
• Last thought on Isolates: they are a separate process so communication between isolates is only done through messages, so basic data should be passed between them and that could give you some headaches if you want to return some big data. (Of course everything is possible with serialization)

Hope this helps you to choose, if not, feel free to comment and we can discuss this further.
