What is Dart thread?

Flutter is single threaded and runs an event loop (like Node. js), you don’t have to worry about thread management or spawning background threads. If you’re doing I/O-bound work, such as disk access or a network call, then you can safely use async/await and you’re done.

Dart isolate is a version of the thread . … The isolate works differently in comparison of Thread. The isolates are independent workers that do not share memory, but instead interconnect by passing message over channels. Since isolates completes its task by passing message thus it need a way to serialize a message.

In Documentation, Dart is Single Threaded but to perform two operations at a time we use future objects which work same as thread. Use Future objects (futures) to perform asynchronous operations. If Dart is single threaded then why it allows to perform asynchronous operations.

Each Dart isolate has a single thread of execution and shares no mutable objects with other isolates. To communicate with each other, isolates use message passing.

Dart is indeed multi-threaded .4 Mar 2021

By design, Dart is a single-threaded programming language . That’s mean we have asynchronous code across application. When a program starts, it creates something that is called Isolate. When isolated created, the microtask manager executes all events asynchronously.8 Eki 2019
