How to make a timer in React Native?

Question

React Native

Hello!
I tried to make a timer through setInterval and this.setState , but with this approach, the entire application stopped and behaved somehow inappropriately.
Here is an excerpt of my NOT working code:

timer() {
    let timer = setInterval(() => {
      this.setState({
        seconds: this.state.seconds + 1
      })
    }, 1000)
  }

render() {
return(
{this.timer()}
<Text>{this.state.seconds}</Text>
)}

Tell me how to make a timer correctly
