Here’s an English description of loop structures in Dart:

Loop Structures in Dart

In Dart, loop structures are used to repeatedly execute a block of code until a certain condition is met. Dart provides several main types of loop structures, including the for loop, while loop, do-while loop, and for-in loop. Below is a detailed introduction and examples of these loop structures.

1. for Loop

The for loop is used a block of code a known number of times.

dart

for (initialization; condition; increment/decrement) {

// Loop body

}

Example:

dart

for (int i = 0; i < 5; i++) {

print('Iteration: $i');

}

2. while Loop

The while loop repeatedly executes a block of code as long as the condition is true.

dart

while (condition) {

// Loop body

}

Example:

dart

int count = 0;

while (count < 5) {

print('Count: $count');

count++;

}

3. do-while Loop

The do-while loop is similar to the while loop, but it executes the loop body at least once before checking the condition.

dart

do {

// Loop body

} while (condition);

Example:

dart

int count = 0;

do {
