I have two components in react native and I'm unable to close a modal from my child component.

ListTrips - Parent

ModalAddTrip - Child

ListTrips.js

import ModalAddTrip from './ModalAddTrip';

....

....

this.state = {

    isModalAddTripVisible: false

} 

....

handleDismissModalAddTrip = () => {

    this.setState({ isModalAddTripVisible: false });

};



closeModal() {

    this.refs.ModalAdd.handleDismissModalAddTrip();

}

....



<ModalAddTrip

    ref="ModalAdd"

    isVisible={this.state.isModalAddTripVisible}

    onBackDropPress={this.handleDismissModalAddTrip}

    closeModal={() => this.closeModal()}

    onRequestClose={this.handleDismissModalAddTrip}

/>

ModalAddTrip.js

<Modal

    isVisible={isVisible}

    onBackdropPress={onBackDropPress}

    closeModal={this.props.child}

>

<Button

    style={{ fontSize: 18, color: 'white' }}

    containerStyle={{

        padding: 8,

        marginLeft: 70,

    }}

    onPress={this.closeModal}

>

I'm unable to close the modal once I open it. I know its something to do with referencing/props but I've messed around with it for hours and I cannot get anywhere. I was trying something along the lines of this.props.closeModal; along with switching the ref to the child component but it didn't work either. inside a function in ModalAddTrip but that wouldn't work either.

Any help is greatly appreciated.
Thanks

Here is a solution which I use to handle modal.

export default class MyModal extends React.Component<Props, State>{



  constructor(props: Props){

    super(props);

    this.state = {

      visible: false,

    }

  }



  // Use this method to toggle the modal !

  toggleModal = () => {

    this.setState({visible: !this.state.visible});

  }





  render(){

    return(

      <Modal

      isVisible={this.state.visible}

      hideModalContentWhileAnimating

      onBackdropPress={() => {

        this.toggleModal();

      }}

      useNativeDriver

      >

        <View style={{backgroundColor: "white", padding: 5}}>

        </View>

      </Modal>

    );

  }

}

If I press behind it, the modal will close -> it can close itself.

Now to manage it from the parent component just get a ref from your modal :

  <MyModal 

    ref={ref => {

      this.myModal = ref;

    }}

  />

And you can toggle it from the parent component :

toggleMyModal = () => {

    if(this.myModal){

      this.myModal.toggleModal();

    }

  }

Let me know if you got it working :)

ModalAddTrip.js

  _toggleModal = () =>

      this.setState({ isVisible: !this.state.isVisible });

  ....



  render() { 

  ....

   <Modal

    isVisible={isVisible}

    onBackdropPress={onBackDropPress}

  >

      <Button

            style={{ fontSize: 18, color: 'white' }}

            containerStyle={{

              padding: 8,

              marginLeft: 70,

            }}

            onPress={this._toggleModal} >

</Modal>
