reset method
Reset the read/write offsets in the buffer.
If hard
is true, reset the _recordedReadCount
and
_recordedWriteCount
accumulators also.
If hard
is false (default), add the current readCount to the
_recordedReadCount
and writeCount to the _recordedWriteCount
.
The length of the buffer does not change.
Implementation
void reset({bool hard = false}) {
resetRead(hard: hard);
resetWrite(hard: hard);
}
