This package can create a time interval of list in map of from and to means it can create a gap nof time or break the time in small time intervals.

Features

you can get time interval in list of map .
you can get time interval in TimeOfDate formate.
This include null safty also.

Getting started

To use this you must have

* starting time (in TimeOfDate) * ending time (in TimeOfDate) * gap time from (in TimeOfDate) * gap time to (in TimeOfDate) * interval (in int)

== Now, Just call generateTimeIntervals ==

Usage

List<Map<String,Time>>? timing;
 
  // --- Services timing ---
   Time _openingTime = const Time(
    hour: 08,
    minute: 00,
  );
  Time _closingTime = const Time(
    hour: 16,
    minute: 00,
  );
  Time _lunchTimeTo = const Time(
    hour: 14,
    minute: 00,
  );
  Time _lunchTimeFrom = const Time(
    hour: 13,
    minute: 00,
  );
  int _avgTime = 10;

 @override
  void initState() {
    // TODO: implement initState
    getIntervalOfServices();
    super.initState();
  }

 void getIntervalOfServices(){
  timing =  generateTimeIntervals(avgTime: _avgTime,closingTime: _closingTime,openingTime: _openingTime,lunchTimeFrom: _lunchTimeFrom,lunchTimeTo: _lunchTimeTo ); 
 }
