How do I check if a File exists in darts?

File(path). exists() returns a future bool. To implement this in a stateless widget, or to just check using if statement, use File(path). existsSync() which returns a bool data type.

These are four steps to create folder in Flutter:

Create a new Directory to give access the directory with the specified path: var myDir = Directory(‘myDir’); Most instance methods of Directory exist in both synchronous and asynchronous variants, for example, create and createSync.

A Directory is an object holding a path on which operations can be performed . The path to the directory can be absolute or relative. It allows access to the parent directory, since it is a FileSystemEntity.
