*****How It Works
n rows, each containing n stars. The simplest nested-loop pattern — the foundation for all grid patterns.
Practice Variations
- Try printing the pattern with a different character (e.g.,
#or+) - Modify the code to accept the pattern size as user input
- Combine this pattern with its inverse to create a diamond or hourglass
Complexity
- Time: O(n²) — total characters printed grows quadratically
- Space: O(n) — longest row is O(n) characters

FAQ
How do you print the Solid Square Star pattern in Dart?
Use nested loops: the outer loop walks through the rows while the inner loop prints the characters or values for each row. The complete Dart implementation with expected output is shown in the sections above.
What is the time complexity of the Solid Square Star pattern in Dart?
The time complexity is O(n²) and the space complexity is O(n), since the pattern is built with a fixed number of loop counters and printed row by row.
Happy coding!
