readTime method
Returns the average read time duration of the given String in seconds.
The default calculation is based on 200 words per minute.
You can pass the wordsPerMinute
parameter for different read speeds.
Example
String foo = 'Hello dear friend how you doing ?';
int readTime = foo.readTime(); // returns 3 seconds.
Implementation
int? readTime({int wordsPerMinute = 200}) {
if (this == null) return null;
if (this!.isEmpty) return 0;
final words = this!.trim().split(RegExp(r'(\s+)'));
final magicalNumber = words.length / wordsPerMinute;
return (magicalNumber * 100).toInt();
}
