Can you list the main data structure types and briefly explain their applications?

Main types of data structures and their applications:

• Array — an ordered set of elements of fixed size. Used for storing data with quick access by index.
• List — a dynamic collection of elements, allowing adding and removing elements. In Flutter, List is often used to store sequences.
• Stack — a data structure with the LIFO (last-in, first-out) principle. Used for implementing undo actions, graph traversal.
• Queue — a structure with the FIFO (first-in, first-out) principle. Used in scheduling and event processing tasks.
• Hash table (Map/Dictionary) — stores key-value pairs with quick access by key. In Flutter, this is Map.
• Tree — a hierarchical structure, such as a binary search tree for fast search and sorting.

In Flutter/Dart, most often List, Set, and Map are used to solve most data-related tasks.
