Loops are fundamental constructs in programming that allow you to execute a block of code repeatedly based on a condition or a set of values. In Dart, the primary looping constructs are `while` loops and `for` loops. This article will explore these constructs in detail, providing you with the knowledge to use them effectively in your Dart programs.

`while` Loops

A `while` loop executes a block of code as long as a specified condition is true. It is useful when the number of iterations is not known beforehand and depends on a condition.

Syntax

Simple Example

In this example, the program prints the value of `counter` from 0 to 4. The loop continues to execute as long as `counter` is less than 5.

Infinite Loop

Be careful with `while` loops to avoid creating infinite loops, where the condition never becomes false.
