Animation not working

[bfp4]

I created this laoding icon a while back and tried using it in a new project. I for some reason won't work and I can't figure out why.

`

    export default function Loading(props){
        const flipAnim = {
            0: {
                transform: [{rotate: "0deg"}]
            },
            0.25: {
                transform: [{rotate: "180deg"}]
            },
            0.5: {
                transform: [{rotate: "180deg"}]
            },
            0.75: {
                transform: [{rotate: "360deg"}]
            },
            1: {
                transform: [{rotate: "360deg"}]
            }
        }

        const fillAnim = {
            0: {
                height: "0%"
            },
            0.25: {
                height: "0%"
            },
            0.5: {
                height: "100%"
            },
            0.75: {
                height: "100%"
            },
            1: {
                height: "0%"
            }
        }
        
        return (
            <View style={{...styles.loadingCon, height: props.size}}>
                <Animatable.View 
                    style={styles.loader} 
                    animation={flipAnim}
                    duration={2000}
                    iterationCount="infinite"
                    easing="linear"
                >
                    <Animatable.View
                        style={styles.loaderInner}
                        animation={fillAnim}
                        duration={2000}
                        iterationCount="infinite"
                        easing="linear"
                    >
                    </Animatable.View>
                </Animatable.View>
            </View>
        )
    }

    const styles = StyleSheet.create({
        loadingCon: {
            justifyContent: "center",
            alignItems: "center"
        },
        loader: {
            width: 40,
            height: 40,
            borderWidth: 5,
            borderColor: constansts.colors.blues,
            borderRadius: 4
        },
        loaderInner: {
            width: "100%",
            backgroundColor: constansts.colors.blues,
        }
    })`
