parseViewCount method
Parse view count from a string formatted as an integer and its magnitude. Example: 5 views, 1.5K views, 2.3M views, 3.4B views. If this fails returns null.
Implementation
int? parseViewCount() {
final match = _viewCountExp.firstMatch(this);
if (match == null) {
return null;
}
if (match.groupCount != 2) {
return null;
}
final count = double.tryParse(match.group(1) ?? '1');
final unitStr = match.group(2);
final unit = switch (unitStr) {
'B' => 1000000000,
'M' => 1000000,
'K' => 1000,
_ => 1
};
return (count! * unit).toInt();
}
