This picker wheel uses a fixed row height of 44 pixels by default, with deterministic snapping that ensures selected items align perfectly in the center. The picker wheel supports configurable visible item counts, with an odd number recommended for balanced alignment. This picker wheel can loop through data repeatedly, enabling continuous scrolling without reaching the end .
The @limosea/react-native-wheel-picker library offers enhanced picker wheel features including haptic feedback and customizable styling. This picker wheel supports multi-column pickers, making it suitable for complex input scenarios. The picker wheel prevents scroll event penetration, ensuring smooth interaction within nested scrollable views. Real-time callback functionality allows developers to respond immediately as users interact with the picker wheel .
The @sinandsean/react-native-wheel-picker library provides another high-performance picker wheel implementation. This picker wheel is available for both iOS and Android platforms, with native performance on each. The picker wheel includes unit label support, making it suitable for measurement selection. The picker wheel also offers TypeScript support, improving developer productivity .
Key Parameters and Configuration
The picker wheel can be configured through various parameters that control its behavior and appearance. The itemHeight parameter determines the fixed height of each item in the picker wheel, affecting the snap interval. The visibleItemCount parameter controls how many items are visible in the picker wheel at once, with default values typically set to an odd number like 3 or 5 .
The picker wheel includes animation parameters that control visual effects during scrolling. The perspective parameter sets the camera distance for the 3D transform effect on the picker wheel. The maxRotation parameter defines the maximum angle of rotation for items at the edges of the picker wheel. The picker wheel also supports minimumOpacity and minimumScale parameters, which control how faded and scaled items become at the edges .
