The available control widgets for selection in Material Design are as follows:

• Checkbox allows the selection of multiple options in a list.
• Radio allows a single selection in a list of options.
• Switch allows the toggle (on/off) of a single option.
• Slider allows the selection of a value in a range by moving the slider thumb.

On the iOS Cupertino side, some of these widget functionalities do not exist; however, there are some alternatives available:

• CupertinoActionSheet: An iOS-style modal bottom action sheet to choose an option among many.
• CupertinoPicker: Also a picker control. It's used to select an item in a short list.
• CupertinoSegmentedControl: Behaves like a radio button, where the selection is a single item from an options list.
• CupertinoSlider: Similar to Slider in Material Design.
• CupertinoSwitch: This is also similar to Material Design's Switch.
