1. For Loop:
The for loop in Dart is similar to other programming languages like JavaScript and C. It’s primarily used for iterating over a range of values or elements in a collection. The syntax of a basic for loop in Dart looks like this:

for (initialization; condition; increment) {
// code to be executed
}

Here’s a breakdown of each part:

• Initialization: Initialize a variable or counter before the loop starts.
• Condition: Define the condition for executing the loop. If the condition evaluates to true, the loop continues; otherwise, it exits.
• Increment: Update the loop variable after each iteration.

Example:

for (var i = 0; i < 5; i++) {
print('Value of i: $i');
}

2. While Loop:
The while loop in Dart repeatedly executes a block of code as long as a specified condition is true. Unlike the for loop, it doesn’t require an initialization step or an increment/decrement operation within the loop itself.

while (condition) {
// code to be executed
}

Example:

var count = 0;
while (count < 5) {
print('Count: $count');
count++;
}

3.  do-while Loop:
Similar to the while loop, the do-while loop in Dart executes a block of code at least once before evaluating the loop condition. It’s useful when you need to ensure that a block of code runs at least once, regardless of whether the condition is true or false.

do {
// code to be executed
} while (condition);

Example:

var x = 0;
do {
print('Value of x: $x');
x++;
} while (x < 3);

4. For-in Loop:
The for-in loop in Dart is used to iterate over the elements of an iterable (such as lists, sets, or maps). It simplifies the process of iterating through collections by abstracting away the details of indexing. The syntax of a for-in loop in Dart looks like this:

for (var item in iterable) {
// code to be executed
}

Here, item represents the current element being iterated over, and iterable is the collection being traversed.

Example:

var myList = [1, 2, 3, 4, 5];
for (var number in myList) {
print('Number: $number');
}
