Page does not update after deep link to same page is clicked

I am using React-navigation to handle deep link.

Let's say I am in BusinessProfile Page that is currently displaying detail for BUSINESS B1. I click on home button and minimize my app. When I click on a deep link, myapp://BusinessProfilePage/B2, It takes me to the BusinessProfile Page but still displays result for Business B1. The function to get business detail for B2 is not called.

How can I make the page refresh when a page opens from a deep link.

P.S. I cannot call the function in componentDidUpdate because when the function to get Business Detail is called, it updates the state which then evoke componentDidMount again.

    You should call your function in a listener for the change event of AppState:

    import { AppState } from 'react-native';
    componentDidMount() {
      AppState.addEventListener('change', this._handleAppStateChange);
    _handleAppStateChange = (nextAppState) => {
      if (nextAppState === 'active') { // App has come to the foreground
        if(this.state.currentBusiness.ID != (ID received in deep link)) // Need to get data
             this.getBusiness(ID received in deep link);

    Taking my best guess here with regards to variable names as you didn't provide and code (you should always include code samples when describing your issue :) ), but you get the idea.
