Introduction of Dart Loops
Dart Loops are a fundamental programming construct in Dart, as in any other programming language, enabling the execution of a block of code multiple times. Dart provides various types of loops that cater to different scenarios, ensuring developers can implement repetitive tasks efficiently and effectively. Here’s a detailed look at the types of loops available in Dart, complete with examples.
1. for Loop
The for loop is ideal for running a block of code a specific number of times, with clear control over the initialization, condition, and iteration statement.
for (int i = 0; i < 10; i++) {
print('Loop iteration: $i');
}
2. for-in Loop
The for-in loop is used for iterating over elements in an iterable object, such as Lists or Sets, providing a concise way to access each item directly.
List<String> names = ['Alice', 'Bob', 'Charlie'];
for (var name in names) {
print(name);
}
3. while Loop
The while loop repeats a block of code as long as a specified condition evaluates to true. It’s useful when the number of iterations is not known before the loop starts.
int number = 5;
while (number > 0) {
print('Current number: $number');
number--;
}
4. do-while Loop
Similar to the while loop, the do-while loop ensures that the block of code is executed at least once, as the condition is checked after the code execution.
int number = 0;
do {
print('Number is $number');
number++;
} while (number < 5);
Conclusion Dart Loops
Dart’s looping constructs are powerful tools for handling repetitive tasks, data manipulation, and flow control within applications. Each type of loop offers unique advantages depending on the situation, making them indispensable in many programming scenarios.
