timecode

Description:

timecode

This package implements the Timecode SMPTE spec.
Features #
A Timecode object has a framerate and a number of frames. Various mathematical operations
can be done on the object, and it will be able to understand how to convert its frame number
to a human readable SMPTE string like 01:23:45:01 where the form is HH:MM:SS:FF (hours,
minutes, seconds, frames).
Timecode objects can also be configured to use milliseconds instead of frames or to output
SMPTE code with fractional seconds instead of frame numbers. In either case, the output will
look like this 01:23:45.123 where the last three digits are milliseconds.
Usage #
Add to your pubspec.yaml.
$ dart pub add timecode

Import in your file and create a Timecode object.
import 'package:timecode/timecode.dart';

var timecode = Timecode(framerate: TimecodeFramerate(24));
print(timecode);
for (var i = 0; i < 100; i++) {
timecode.next();
print(timecode);
}
