how to refresh when clicking a button in react code example
Example: how to rerender a page in React when the user clicks the back button
We had a similar desire and solved it by passing a refresh function from the parent to the child.
for example, when you open the child, you would have something like navigate('Child', { refresh: refreshFunction }
You can then access this function in the child ( via something like this.props.navigation.state.params.refresh(); ) before the back action.
