while Loop in Dart
A while loop is a programming construct that allows you to execute a specific block of code as long as a certain condition is true.
The syntax for a while loop in Dart is as follows:
loop.dart
123while (condition) { // Statements to be executed while a condition is `true` }
- Before entering the loop, the condition in parentheses is checked. If it’s
true, the loop runs. - After each run, the condition is checked again. If still
true, it repeats. - When the condition becomes
false, the loop stops and the program continues.
It is important to remember that while loops can be infinite if the condition never becomes false. Remember, it is essential to check the condition carefully.
main.dart
12345678void main() { int counter = 0; while (counter < 5) { print(counter); counter = counter + 1; } }
The while loop runs as long as counter is less than 5. Since counter starts at 0, the loop executes five times, increasing counter by 1 on each iteration.
