FirebaseQuery<T> class

A type-safe wrapper for Firestore queries.

Provides a fluent interface for building and executing Firestore queries with proper type conversion. The generic type T represents the model class for the query results.

Example:

final activeUsers = usersCollection
  .query()
  .where('status', isEqualTo: 'active')
  .where('age', isGreaterThan: 18)
  .orderBy('lastSeen', descending: true)
  .limit(10);

// Get results once
List<User> users = await activeUsers.get();

// Or listen to real-time updates
activeUsers.stream().listen((users) {
  print('Got ${users.length} active users');
});
