update state from Scene

[lokomass]

Hi,

It's impossible to update state from a Scene component

Current behaviour

State is not updated

Expected behaviour

State update with function passed as arg

Code sample

...

const Render = (props) => {
  const { setReady } = props
  return (
    <View style={styles.container}>
      <WebView
        source={{...}}
        onLoadEnd={() => setReady(false)}
      />
    </View>
  )
}

const example = (props) => {
  const [ready, setReady] = React.useState(true)
  ...
  const Scene = ({ route }) => {
    return (
      <Render
        ...
        setReady={setReady}
      />
    )
  }
  return (
    <TabView
		...
		renderScene={Scene}
		...
	/>
  )
}

export default example

Couldn't find version numbers for the following packages in the issue:

• react-native-tab-view
• react-native-gesture-handler
• react-native-reanimated

Can you update the issue to include version numbers for those packages? The version numbers must match the format 1.2.3.
