VisualizaçõesI receive an undefined value when I pass the value of a variable through props from a parent component to a child component
I create a variable pointsFilter in app.js and through props I send the value to a child component in this case the component is Map but when I want to extract the value I get undefined and when i do a console.log in app i get the value but when i do the same in map.js i get undefined
app.js
const [pointsFilter, setPointsFilter] = useState(true)
<Map onLongPress={handleLongPress} puntos={puntos} poinstFilter={pointsFilter} />
map.js
export default ({ onLongPress, puntos, pointsFilter }) => {
console.log(pointsFilter)
return (
<Mapview style={styles.map} onLongPress={onLongPress} >
{pointsFilter && puntos.map(x => <Marker coordinate={x.coordinate} title={x.name} key={x.name} />)}
</Mapview>
)
}

On app.js you pass poinstFilter and on Map, you try to extract pointsFilter. Use the same name on both sides. Moreover, I don't see the component name on your Map component. You may create components as
const export default Map= ({ onLongPress, puntos, pointsFilter })
