pass props in tabs in react native

问题

I would like to know how to pass a state from my main page to the Tabs? Currently I'm using navigate to transfer props from one page to another page but from Tabs it seems I cannot do that, do you have a function or sample code on how to pass props to the Tabs?

回答1:

Simply Pass the state as props like this:

<SampleComponent 
   sampleProps={this.state.MyMainPageState} 
/>

from there you can access it at your SampleComponent as props ;)

inside SampleComponent you can try logging it:

//this is the state from your mainPage
const {sampleProps} = this.props; 
 console.log(sampleProps); 

that should do it
