createSync method
- {bool recursive: false}
Synchronously create the file. Existing files are left untouched by createSync. Calling createSync on an existing file might fail if there are restrictive permissions on the file.
If recursive is false, the default, the file is created
only if all directories in the path exist.
If recursive is true, all non-existing path components are created.
Throws a FileSystemException if the operation fails.
Implementation
void createSync({bool recursive: false});
