open method Null safety
- {FileMode mode: FileMode.read}
Open the file for random access operations. Returns a
Future<RandomAccessFile>
that completes with the opened
random access file. RandomAccessFiles must be closed using the
RandomAccessFile.close method.
Files can be opened in three modes:
FileMode.read: open the file for reading.
FileMode.write: open the file for both reading and writing and truncate the file to length zero. If the file does not exist the file is created.
FileMode.append: same as FileMode.write except that the file is not truncated.
Implementation
Future<RandomAccessFile> open({FileMode mode: FileMode.read});
