To print a Diamond Pattern in Dart, we use nested loops. The outer loop controls the rows and the inner loops control the spaces and stars (*) to form the pattern.
In this example,
printDiamond
that takes the desired number of rows n
as a parameter.for
loops, where the outer loop runs from 1 to n
and the inner loops control the spaces and stars in each row.void printDiamond(int n) {
for (int i = 1; i <= n; i++) {
String spaces = ' ' * (n - i);
String stars = '*' * (2 * i - 1);
print(spaces + stars);
}
for (int i = n - 1; i >= 1; i--) {
String spaces = ' ' * (n - i);
String stars = '*' * (2 * i - 1);
print(spaces + stars);
}
}
// Example usage
void main() {
printDiamond(5);
}
