Introduction to Dart

1. First Acquaintance with Dart

This section will tell you about the advantages of Dart and why you should learn it. We'll also write the first programs on Dart

Basic Math Operations

2. Variables and Data Types

Numbers and text are an integral part of every application and mobile application. This section will teach you how to work with these and other data types.

Data Types

Variables

Properties of Numbers

Bool, Equality and Relational Operators

3. Conditional Statements

Previously, our code only worked linearly from top to bottom. In this section, we will learn how to control the code flow.

if Statement

if...else Statement

else-if Statement

switch-sase Statement

4. List and String

Every serious program has a lot of data. Data is usually stored in sets. In this section, we will explore data collections.

String Properties and Methods

5. Loops

In programs, instructions often need to be repeated many times. To do it quickly, we can use loops. In this section, we will study cycles.

Introduction to Loops

while-Loops

Do-while

for-Loops

Increment and Decrement

Break and Continue

break

In Dart, break is a statement used to exit a loop. The break statement can be used in any loop, including while, for, and do-while loops.

The syntax for the break statement is as follows:

When the break statement is encountered in code, it terminates the execution of the loop in which it is located. This means that any other iterations of the loop will not be executed.

Example

The break statement is often used to exit a loop if a condition meets specific requirements. For example, the following code prints all numbers from 1 to 10, but it breaks the loop if it encounters the number 5:

main.dart

continue

Continue is a statement used to skip the current iteration of a loop. The continue statement can be used in any loop, including while, for, and do-while loops.

The syntax for the continue statement is as follows:

Example

The continue statement is often used to skip certain values or conditions

main.dart

As you can see, the continue statement allows us to control which list items will be output to the console.
