Animated & Keyboard

Animated

AnimatedLegendList supports animated props with React Native’s Animated.

import { AnimatedLegendList } from "@legendapp/list/animated";

export function AnimatedExample() {
  const animated = useRef(new Animated.Value(0)).current;

  useEffect(() => {
    Animated.timing(animated, {
      toValue: 1,
      duration: 1000,
      useNativeDriver: true,
    }).start();
  }, []);

  return (
    <AnimatedLegendList
      data={data}
      renderItem={renderItem}
      style={{ opacity: animated }}
    />
  );
}

Note that this is just a wrapper around the normal createAnimatedComponent so you can use that if you prefer.

const AnimatedLegendList = Animated.createAnimatedComponent(LegendList);

Reanimated

The Reanimated version of AnimatedLegendList supports animated props with Renimated. Note that using Animated.createAnimatedComponent will not work as it needs more boilerplate, so you should use this instead.

import { AnimatedLegendList } from "@legendapp/list/reanimated";
import Animated, { useSharedValue, useAnimatedStyle, withSpring } from "react-native-reanimated";

export function ReanimatedExample() {
  const scale = useSharedValue(0.8);

  useEffect(() => {
    scale.value = withSpring(1);
  }, []);

  return (
    <AnimatedLegendList
      data={data}
      renderItem={renderItem}
      style={useAnimatedStyle(() => ({
        transform: [{ scale: scale.value }]
      }))}
    />
  );
}

Keyboard Controller

LegendList integrates with the KeyboardAvoidingView in react-native-keyboard-controller for smoother keyboard interactions. Note that it is important to use behavior="position" for best compatibility with Legend List.

import { KeyboardAvoidingView, KeyboardProvider } from "react-native-keyboard-controller";
import { LegendList } from "@legendapp/list/keyboard-controller";

export function KeyboardControllerExample() {
  return (
    <KeyboardProvider>
      <KeyboardAvoidingView
        behavior="position"
        keyboardVerticalOffset={headerHeight}
      >
        <LegendList
          data={data}
          renderItem={renderItem}
          behavior="position"
        />
      </<KeyboardAvoidingView>
    </KeyboardProvider>
  );
}
