operator [] method

MimeThread? operator [](
  1. int threadIndex
)

Eases access to the MimeThread at the specified threadIndex or null when it is not yet loaded.

Note that the threadIndex is expected to be based on full threadData, meaning 0 is the newest thread and length-1 is the oldest thread.

Implementation

MimeThread? operator [](int threadIndex) {
  final index = (length - threadIndex - 1);
  if (index < 0 || threadIndex < 0) {
    return null;
  }
  return threads[threadIndex];
}
