Dart Isolate在Flutter for Android/ iOS中是如何实现的？

Question

I have a problem understanding Dart Isolates and how they are implemented in Flutter for Android/ iOS. This answer states that "Dart is compiled to native machine code (ARM, Intel, ...) executable and bundled with some native platform code (Java, Kotlin, Objective-C/Swift) to interact with the native platform."

When I use a Dart Isolate in Flutter, eg for Android, is the Isolate compiled to something like Workmanager , or does it "only" use the Dart Isolate itself?

Answer 1

Flutter is a high level implementation of things, you don't need to think on processor level, system process level it is all handled by Target OS,

On low level a Thread is a light-weight process that performs some task and uses system resources like CPU,

As per ISOLATE specification

Each Dart isolate has a single thread of execution and shares no mutable objects with other isolates.

Using Isolate you create a separate thread that handles the separate task without intercepting the main thread of your dart/flutter App,
