2. What is Dart?
Dart is a modern, open-source, and object-oriented programming language developed by Google.
It is designed to be a scalable and efficient language for building a wide range of applications, from
mobile apps to server-side development.
Dart's syntax is similar to Java and C#, making it easy for developers familiar with those languages
to pick up. It also features strong typing, which helps catch errors early in the development
process.

3. Dart Language Syntax
Dart's syntax is modern and easy to learn, drawing inspiration from languages like Java and C#. It
features clean and concise code, with a focus on readability and maintainability.
1. Dart uses camelCase for variable and function names, making the code more intuitive and
easy to understand.
2. The language supports type annotations, allowing for strong static typing to catch errors
early in the development process.
3. Dart provides a wide range of built-in data types, including numbers, strings, booleans,
and more, making it easy to work with various types of data.

4. Dart Data Types
Dart is a strongly-typed language, offering a rich set of built-in data types to handle various types of
data. These include numbers, strings, booleans, lists, maps, and even dynamic types for
greater flexibility.
1. Numbers in Dart can be integers, doubles, or big integers for larger values.
2. Strings in Dart can be defined using single quotes, double quotes, or triple quotes for
multiline strings.
3. Dart also supports collections like lists and maps to store and manipulate groups of data.

5. Dart Variables and Constants
Dart allows you to declare variables and constants to store and manipulate data in your
applications. Variables can be assigned different values during runtime, while constants have a
fixed value that cannot be changed.
1. Variables in Dart are declared using the var, dynamic, or specific data type keywords, like
int, double, or String.
2. Constants in Dart are declared using the const or final keywords, which ensures their
value remains fixed throughout the program's execution.
3. Dart's type inference feature can automatically determine the data type of a variable based
on its initial value, simplifying variable declarations.

6. Dart Operators and Expressions
Dart offers a comprehensive set of operators, allowing you to perform various operations on data.
These include arithmetic, assignment, comparison, logical, and more. Expressions in Dart combine
operands and operators to produce a new value, enabling you to create complex logic within your
code.
1. Dart's arithmetic operators include +, -, *, /, and %, allowing you to perform basic math operations.
2. The assignment operators, such as =, +=, and -=, help you efficiently assign values to variables.
3. Dart's comparison operators, like ==, !=, >, and <, enable you to compare values and
make decisions in your code.

7. Dart Control Flow Statements
Dart provides a rich set of control flow statements to help you make decisions and control the
execution of your code. These statements include if-else, for loops, while loops, and switch-
case constructs, allowing you to write complex logic within your Dart applications.
1. The if-else statement enables you to make decisions based on specific conditions, allowing
your program to take different actions based on the evaluated expression.
2. Dart's for loops and while loops allow you to repeatedly execute a block of code, either a
fixed number of times or until a certain condition is met.
3. The switch-case statement provides a concise way to handle multiple conditions, making it
ideal for scenarios where you need to perform different actions based on a single variable
or expression.

8. Dart Functions and Methods
In Dart, functions and methods are first-class citizens, allowing you to define reusable pieces of
code. These constructs help you organize your logic, improve code readability, and promote code
reuse.
1. Dart functions can be named or anonymous, and they can accept parameters and return values.
2. Methods are functions that are defined within a class and can access the instance
variables and other methods of that class.
3. Dart also supports higher-order functions, where functions can be passed as arguments
or returned from other functions, enabling more advanced programming techniques.

9. Dart Classes and Objects
In Dart, classes are the fundamental building blocks for creating complex and reusable objects.
They encapsulate data and behavior, allowing you to model real-world entities and concepts within
your applications.
1. Classes in Dart define the structure and attributes of an object, using properties and
methods to represent its state and behavior.
2. Objects are instances of a class, and they can be created using the new keyword or the
shorthand constructor syntax.
3. Dart supports inheritance, allowing you to create subclasses that inherit properties and
methods from a superclass, promoting code reuse and polymorphism.
