very very comprehensive.
Please explain it further with .map()...toList() methods, as in how do i know when its required in my code and what do they do?

[@dbestech]

You call .map() on a map object. You call this because you may want to change the value of the map's key or do something using those keys and values. Once you are done you return them as a list using toList(). If you use toList() it becomes a list. If it's a list them you can access the items using index.
So whenever you need a list from a map you would do this.
mapObject.entries.map((e)=>e.value).toList();

easy to follow, great explanation. why cant i just store the decode json directly in the map?. i don't understand why the fromjson method is needed?

[@indraworks6050]

as beginer in dart i just read it doc,that shown fromJson is one of Factory constructor method,
Factory is class contructor that under main class which no produce instance like comons constuctor
but hasa the return value if Facotry constructor make task order to subordinary class
this fromJson method conver json format to object format ,i hope you will understand it
on the above presentation Mr.dbestech i think mr.dBestech use the Factory constructor but forget to put infront of the Task class or formJson on the above mentioned as named Constructor ? :)))
it should be like this : Factory Task.fromJson(Map json)
but in this case mr.Dbestech use named constructor because not mentioned write factory,
so the task in the above explanation is instance from named class :
Task task = new Task..fromJson(args as json format)
so from json = {"key1":value1, "key2":value2} become this : value1, value2 ( from method above0

@@dbestech By "keying", you can still maintain your lecture video visible underneath the Subscribe animation while its displayed, instead of green background.

what if the json has no keys and it is just values? like this: ["food", ""sleep", "rest, "breathe"].
