Question 1

How do I add a blur effect to a react-native-hero background?

Accepted Answer

Integrate react-native-blur by wrapping your overlay content in a BlurView component, as shown in the README example. This requires installing and linking react-native-blur separately, adding an extra dependency.

Question 2

react-native-hero vs React Native's ImageBackground: which should I use?

Accepted Answer

react-native-hero offers dynamic sizing and built-in overlays out-of-the-box, while ImageBackground is more lightweight but requires manual layout handling. Choose react-native-hero for automatic adjustments or ImageBackground for full control with less abstraction.

Question 3

How to set a fixed height for the hero unit in react-native-hero?

Accepted Answer

Use the minHeight prop to define a static height, which overrides the dynamic sizing based on content. This is documented in the component props table and useful for consistent layouts.

Question 4

Does react-native-hero support video backgrounds or only images?

Accepted Answer

It only supports image backgrounds via the source prop; for video, you'd need to use a custom image component or modify the component, as it's not a built-in feature.

Question 5

Is react-native-hero compatible with Expo projects?

Accepted Answer

Yes, but features like custom image components (e.g., react-native-fast-image) may require ejecting or using compatible Expo libraries, so check dependencies and linking requirements carefully.

Question 6

What's the best way to make overlay text responsive in react-native-hero?

Accepted Answer

Style your text components within the renderOverlay function using React Native's flexible units or libraries like react-native-responsive-fontsize, as the hero handles image sizing but not automatic text scaling.
