create method Null safety

Future<File> create (
  1. {bool recursive = false}
)

Creates the file.

Returns a Future<File> that completes with the file when it has been created.

If recursive is false, the default, the file is created only if all directories in its path alredy exist. If recursive is true, any non-existing parent paths are created first.

Existing files are left untouched by create. Calling create on an existing file might fail if there are restrictive permissions on the file.

Completes the future with a FileSystemException if the operation fails.

Implementation

Future<File> create({bool recursive = false});
