Async programing in Dart

What is Async programing?

Asynchronous operations let your program complete work while waiting for another operation to finish.

Here are some common asynchronous operations:

1. Fetching data over a network.
2. Writing to a database.
3. Reading data from a file.

To perform asynchronous operations in Dart, you can use the Future class and the async and await keywords.

The async and await keywords support asynchronous programming.

Dart library dart:async provides asynchronous support for functions that returns.

1. Future Object
2. Stream Object

Synchronous functions

synchronous operation: A synchronous operation blocks other operations from executing until it completes.

synchronous function: A synchronous function only performs synchronous operations.

Asynchronous functions

asynchronous operation: Once initiated, an asynchronous operation allows other operations to execute before it completes.

asynchronous function: An asynchronous function performs at least one asynchronous operation and can also perform synchronous operations.
