subchannelOf static method

String subchannelOf(
  1. String line
)

The channel an added/removed line travelled on.

The one place such a line is taken apart, and it is safe because the line is the channel, a space and the title: the channel is everything before the first space, and a channel name never contains one.

Implementation

static String subchannelOf(String line) {
  var space = line.indexOf(' ');
  return space < 0 ? line : line.substring(0, space);
}
