Dart Core Libraries: dart:core

Dart's core library, dart:core, is like the foundation or the most basic set of tools that every Dart program automatically gets. It provides essential building blocks for writing Dart code. Here are some simple explanations for what it includes:

1. Numbers and Text (Strings): dart:core helps you work with numbers (like 1, 2, 3) and text (strings). For example, you can do math with numbers or manipulate and combine text.

2. Collections: It gives you ways to organize and store data. Lists are like containers for multiple pieces of information, and maps are like dictionaries where you can look up values by a specific key.

3. Booleans: You can use dart:core to work with true/false values, making decisions in your program.

4. Functions: You can create and use functions to organize your code. Functions are like little tasks that your program can perform.

5. Exceptions: If something unexpected happens in your program, you can use exceptions to handle errors gracefully.

6. Iterators: You can loop through collections of data, like going through a list one item at a time.

7. Symbols: Symbols are like special names you can use in your program. They're often used in more advanced programming scenarios.

In a nutshell, dart:core is like the essential toolkit for doing basic things in Dart. It gives you the fundamental tools you need to work with data, make decisions, and organize your code. It's the foundation that makes Dart programming possible!
