How to print Rhombus Pattern in Dart - Step by Step Examples

How to print Rhombus Pattern in Dart ?

Answer

To print a Rhombus Pattern in Dart, we use nested loops. The outer loop controls the number of rows, and the inner loops control the spaces and stars (*) to form the pattern.

✐ Examples

1 Rhombus Pattern

In this example,

We initialize a variable n to the desired number of rows in the rhombus.
We use two nested for loops, where the outer loop runs from 1 to n and the inner loops control the spaces and stars in each row.
Within the inner loops, we calculate the number of spaces and stars based on the current row number to form the rhombus pattern.

Dart Program

void main() {
  int n = 5;
  for (int i = 1; i <= n; i++) {
    String row = '';
    for (int j = 1; j <= n - i; j++) {
      row += ' ';
    }
    for (int k = 1; k <= n; k++) {
      row += '*';
    }
    print(row);
  }
}
