How to Pass DatepickerIOS Date Object to Firebase (React Native) - react-native

Question

I'm EXTREMELY new at coding, and I took Grinder's course on React Native. I have no idea how to save the datepickerios date object into Firebase. I'm pretty sure something in this code here is incorrect.
Any help would be greatly appreciated. Also, if anyone's looking for a mentee, I'd be grateful for your help. Thanks!
class ScoreForm extends Component {
constructor(props) {
super(props);
this.state = {chosenDate: new Date()};
this.setDate = this.setDate.bind(this);
}
setDate(newDate) {
this.setState({chosenDate: newDate});
}
render() {
return (
<View>
<CardSection>
<Text style={styles.pickerTextStyle}>Enter Date</Text>
</CardSection>
<CardSection>
{/* <Input
label="Date"
placeholder="MM/DD/YY"
value={this.props.date}
onChangeText={value => this.props.scoreUpdate({ prop: 'date', value })}
/> */}
<DatePickerIOS
style={{ flex: 1 }}
mode='date'
date={this.state.chosenDate}
onDateChange={value => this.props.scoreUpdate({ prop: 'date', value })}
/>
</CardSection>
<CardSection>
<Input
label="Score"
placeholder="Add Number"
value={this.props.score}
onChangeText={value => this.props.scoreUpdate({ prop: 'score', value })}
/>
</CardSection>
</View>
);
}
}
const styles = {
pickerTextStyle: {
fontSize: 18,
paddingLeft: 20
}
};
const mapStateToProps = (state) => {
const { date, score } = state.scoreForm;
return { date, score };
};
export default connect(null, { scoreUpdate }) (ScoreForm);
Since I am using Redux, I'm assuming I that I don't want to store it in state, correct? Here is the this.props.ScoreUpdate action:
export const scoreUpdate = ({ prop, value }) => {
return {
type: SCORE_UPDATE,
payload: { prop, value }
};
};
