How to print Pyramid Pattern in Dart

How to print Pyramid Pattern in Dart ?

Answer

To print a pyramid pattern in Dart, you can use nested loops where the outer loop controls the rows and the inner loops control the spaces and stars printed in each row.

✐ Examples

1 Pyramid Pattern with Asterisks (*)

In this example,

We define a function printPyramid that takes an integer n as input to represent the number of rows in the pyramid.
We use nested loops where the outer loop controls the rows and the inner loops control the spaces and stars printed in each row.
Inside the inner loops, we use conditions to determine whether to print a space or a star (*) based on the pyramid pattern.
After each row, we use print() to move to the next line.

Dart Program

void printPyramid(int n) {
  for (int i = 1; i <= n; i++) {
    String row = ' ' * (n - i) + '*' * (2 * i - 1);
    print(row);
  }
}

void main() {
  printPyramid(5);
}

Output
