      </Button>
    </React.Fragment>
  );
}

useState

Pass the value from the useState hook to the isVisible modal prop to set the open state of the modal.

Heading

Use the heading prop to set the heading of the modal. For accessibility purposes, a heading is required. Please provide a heading that accurately describes the content of the modal so a screen reader can provide this description to the user.

Scrollable

Use the scrollable prop to make the content scrollable. Setting the prop to false changes the Modal's content container from a ScrollView to a View. Defaults to true.

Action Buttons

Action Buttons can be placed on either the left or right side of the header using the actionLeft and actionRight props. Use the onActionLeftPress prop to fire a callback when the left action is pressed, and onActionRightPress prop to fire a callback when the right action is pressed.

If one of the actions is an icon, make sure to use the heading and isScreenReadable props on the icon for accessibility.

Footer

Use the footer prop to place content at the bottom of the modal.

Modal Section

Wrap content in a Modal.Section component to add padding to the content.

onClose

iOS

Use onClose to close the modal when swiping the modal down on iOS devices.

() => {
  const [modalVisible, setModalVisible] = useState(false);

  return (
    <Modal
      heading="Swipeable Modal"
      isVisible={modalVisible}
      actionLeft={
        <IconSymbol
          icon="close"
          color="$semantic.color.icon.interactive.rest.primary"
          title="Close"
          isScreenReadable
        />
      }
      onActionLeftPress={() => setModalVisible(false)}
      onClose={() => setModalVisible(false)}
    >
      <Modal.Section>
        <Text>Swipe the modal down</Text>
      </Modal.Section>
    </Modal>
  );
};

Layouts like BottomSheet and Modal can be used in combination with each other to create flows.

Focus Guidance

Abyss does not control the focus of components on the screen when the Modal is toggled off. To meet accessibility guidelines, the focus must be set to the previous node when closed. The useSetFocus hook can be used for this.

For example, if a button is pressed to open a Modal, focus must return to that button once the Modal is closed, so that a screen reader or keyboard user may continue using the app where they left off.
