Create business hours with slots in Kotlin

Please have a look at the attached video for reference and the exact requirements that will be have to be completed are available in the APPOINTFIX APP - please find the Edit Business details section and see the business hour details there, thanks

- display 7 days as shown in video
- you have to select which days you have availability by clicking checkbox, plus sign appears to add slots for the day that has been selected
- when click plus, an hour is added from the time of last available for eg Sunday
- if i click available on sunday default time starts at 9 am to 6 pm and plus sign appears
- when i click 9, i am able to add new start time and when i click 6 new end time, end time cannot be before start time for the day
- when i click plus sign, new row added below with on e hour duration from the end time of the previous end for an hour
- so if the last end time for the day was 6 pm, then the new row starts from 6 pm to 7 pm
- you can keep adding rows at the end only but delete in between
- the last time for the day will be 11.55 pm
- start time and end time for new added rows can also change just like in the main row
