Button class

An interactive TUI button widget that triggers a callback when activated.

Keyboard: When focused is true, pressing Space (' '), Enter ('\n'), or Carriage Return ('\r') will trigger onPressed.
Mouse: Left-clicking (mouse press event) inside the bounds of the button triggers onPressed.

Button(
  text: 'Submit',
  focused: true,
  onPressed: () {
    print('Button clicked!');
  },
);
