Checkbox class

An interactive checkbox widget for toggling boolean flags.

Keyboard: When focused is true, pressing Space (' '), Enter ('\n'), or Carriage Return ('\r') toggles value and triggers onChanged.
Mouse: Left-clicking inside bounds toggles value and triggers onChanged.

Checkbox(
  value: isAgreed,
  label: 'I agree to the terms',
  onChanged: (val) {
    setState(() => isAgreed = val);
  },
);

`onChanged`	`Function(bool)`	Callback triggered when state toggles.
