First, we need a layout to organize everything neatly. So go to the ‘Layout’ section on the left and drag a ‘Vertical Arrangement’ onto the screen. This will help us stack everything one below the other. Now, let's add two text boxes where users will enter numbers. Next, let's add the calculator buttons – plus, minus, multiply, and divide. We need a place to display the result. And that’s it! We now have a fully designed calculator layout! Your screen should now have two text boxes, four buttons, and a label for the result.
Block Section:
Now that we have our calculator layout ready, it’s time to bring it to life! In this step, we'll add logic using Kodular's ‘Blocks’ section to make the buttons actually perform calculations. To create a basic calculator, first drag the ‘when Button_Add.Click’ block onto the workspace, then set ‘Label_Result.Text’ using the ‘set Label_Result.Text to’ block; use the ‘join’ block from the Text section to display the result in the format “Result: 10” by typing “Result: ” in the first slot, then calculate the sum using the ‘+’ block from Math and insert ‘get TextBox1.Text’ and ‘get TextBox2.Text’ wrapped in ‘math convert to number’ blocks—finally, repeat these steps for the subtract, multiply, and divide buttons using their respective math blocks (‘-’, ‘×’, ‘÷’) while being cautious of division by zero, and once all buttons have logic, you’re ready to test the calculator
And that’s it! In just a few minutes, we’ve built a fully functional calculator app using Kodular.
