As shown in the doc, you can do as follows:
// Create a reference to the collection
final collectionRef = db.collection('collectionName');
// Create a query against the collection.
final query = collectionRef.where('locationEvent.${nameL}', isEqualTo: 'jkn');
// Execute the query
query.get().then(
(res) => print("Successfully completed"),
onError: (e) => print("Error completing: $e"),
);
