Flutter中的同步和异步文件操作
Synchronous and asynchronous file operation in Flutter
在我的 Flutter 应用程序中处理文件和目录时，我使用了异步和同步方法，例如 createSync() 和 create or list() 和 listSync() 但我无法理解它们之间的主要区别我可以使用相同功能的两个不同版本之一的场景。
flutter 文档说：-
Most methods in this class occur in synchronous and asynchronous pairs, for example, create and
createSync. Unless you have a specific reason for using the synchronous version of a method, prefer
the asynchronous version to avoid blocking your program.
Dart 和 Flutter 对 Asynchronous Operations 有很好的支持。
看看下面的解释：有帮助。
Key terms:
1)Synchronous operation: A synchronous operation blocks other operations from executing until it completes.
2)synchronous function: A synchronous function only performs synchronous operations.
3)Asynchronous operation: Once initiated, an asynchronous operation allows other operations to execute before it completes.
4)Asynchronous function: An asynchronous function performs at least one asynchronous operation and can also perform synchronous operations.
为什么要使用 Asynchrnous operations and functions？
Asynchronous operations let your program complete work while waiting for another operation to finish. Here are some common asynchronous operations:
Fetching data over a network.
Writing to a database.
Reading data from a file.
To perform asynchronous operations in Dart, you can use the Future class and the async and await keywords.
