create method Null safety
- {bool recursive = false}
override
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 already 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
@override
Future<File> create({bool recursive = false});
