我在 React Native 0.64 应用程序中有一个简单的 Accordion 组件,使用react-native-reanimated 2.1.0. 动画 var 定义为animatedVar. 以下是相关代码:

  const aref = useAnimatedRef();
  const open = useSharedValue(false);
  const animatedVar = useDerivedValue(() => {open.value ? withTiming(1) : withTiming(0)});
  const height = useSharedValue(0);

  const accordStyle = useAnimatedStyle(() => {  //<<== accordStyle causes app stopping working
    return {
      height: height.value * animatedVar.value + 1,
      opacity: animatedVar.value === 0 ? 0 : 1,
    };
  });

const pressAccord = async () => {
    if (height.value === 0) {
      runOnUI(() => {
        "worklet";
        height.value = measure(aref).height;
      })();
    }
    open.value = !open.value;
  };

return (
    <>
      <TouchableOpacity onPress={() => pressAccord()}>
        <View style={styles.titleContainer}>
          <Text>{title}</Text>
          <Animated.View style={iconStyle}>
            <Icon name="chevron-down-outline" size={20}  />
          </Animated.View>
        </View>
      </TouchableOpacity>
      <Animated.View style={[accordStyle]} >  //<<==accordStyle causes app stop working
        <View ref={aref} >
          {children}
        </View>
      </Animated.View>
    </>
  );

如果accordStyle从上面的代码中删除,则手风琴工作正常(我的意思是没有错误)。但app stopped working如果accordStyle包含在style. 但我无法弄清楚有什么问题accordStyle
