Get all the items in the collection, after some modification/operation

collection.push(1).push(2);
collection.all()

Extracts a list of values corresponding to a specified key from each item in the collection.

• Usage: Use pluck to retrieve values of a specific attribute/key from each item in the collection.
• How to Use: Call pluck on the collection and provide the attribute/key name as a string.
• Example:

  Collection collection = Collection([
    {'name': 'Alice', 'age': 20},
    {'name': 'Bob', 'age': 23,'notes':[{'english':20,'french':4},{'french':20,'english':7}]}
  ]);
  
  // Extract 'age' attribute from each item
  var ages = collection.pluck<int>('age');
  
   // Extract 'age' attribute from each item
  var ages = collection.pluck<int>('notes.1.english'); // 7

• Returns: Returns a new collection containing the extracted values of the specified attribute/key from each item.

This method is useful for extracting specific data attributes from a collection for further processing or analysis.

Sorts the collection's items based on the provided criteria.

• Usage: Use sort to arrange items either by a specific attribute/key or by a custom sorting function.
• How to Use: Call sort on the collection and provide either a string representing the attribute to sort by or a custom sorting function.
• Example:

    // for nested object/map in the collection
    collection.sort('notes.courses.dart'); 
    // Sort by the first element of list notes
    collection.sort('notes.0');
    // sort by custum callback
    collection.sort<int>((a, b) => a['age'] - b['age']);

• Returns: Returns the sorted collection.

This method is useful for organizing data in ascending order based on a specific attribute or applying custom sorting logic to the collection.
