how ot make a background color faor evaluationbutton in flutter

To set a background color for an ElevatedButton in Flutter, you can use the style property of the ElevatedButton widget. The style property accepts an instance of the ElevatedButton.styleFrom method, which allows you to define the button's appearance.

Here's an example of how you can set the background color for an ElevatedButton:

  style: ElevatedButton.styleFrom(
    primary:, // Set the background color here
  onPressed: () {
    // Your button's onPressed logic here
  child: Text('Evaluation Button'),

In this example, the primary property of the styleFrom method is set to, which will set the background color of the button to blue. You can replace with any color you desire.

Remember to replace the onPressed callback with your desired logic for the button's functionality. The child property is used to define the text displayed on the button.

I hope this helps! Let me know if you have any further questions.
