Question 1

How do I anchor a popover to a button in React Native?

Accepted Answer

Use the `fromRect` prop with a rectangle obtained by calling `measure()` on the button's ref, as shown in the README example. This provides the exact position and dimensions for anchoring.

Question 2

Does react-native-popover work with React Native functional components?

Accepted Answer

Yes, but the README example uses class components. You can adapt it by using hooks like `useState` and `useRef` to manage state and refs for measurement in functional components.

Question 3

How can I customize the animation of the popover?

Accepted Answer

Use the `customShowHandler` and `customHideHandler` props with functions that define animations using the react-tween-state wrapper API. Refer to the default handlers in the source code for guidance.

Question 4

react-native-popover vs react-native-modal for popovers?

Accepted Answer

react-native-popover specializes in anchored, contextual popovers with precise positioning, while react-native-modal is better for full-screen or centered modals. Choose based on whether you need anchored tooltips or general overlays.

Question 5

How to make the popover appear on top of other elements?

Accepted Answer

Since React Native doesn't support z-index well, use react-native-overlay as recommended in the README, or rearrange your view hierarchy to place the popover last in the render tree.

Question 6

Does react-native-popover support accessibility features?

Accepted Answer

The README doesn't mention accessibility. You'll need to manually add accessibility props like `accessible` and `accessibilityLabel` to the popover content for screen reader support.
