react-native update state automatically
I am using mobx to pass state.
First I store some data to mobx.
For example, in the FirstScreen, I store some data using mobx: store.data = 'somedata'
Then, I want to pass this data in my SecondScreen, so I do:
<Button onPress={()=> this.setState({putsomeData:store.data})}>
<Text>update</Text>
</Button>
This would work fine. But is there a way I could listen to the update and automatically update the state without using the button?

Setting your state in a lifecycle method does not fit your question? For example incomponentDidMount()
of the SecondScreen.
