If you've ever struggled with complex filters in Firebase, you’ll love Filter.and()
and Filter.or()
. These let you easily combine multiple conditions without chaining .where()
calls endlessly.
🔥 AND queries:
Need all conditions to be true? Just wrap them in Filter.and()
.
query.where(Filter.and(
Filter("status", isEqualTo: "active"),
Filter("role", isEqualTo: "admin"),
));
⚡ OR queries:
Need at least one condition to match? Use Filter.or()
.
query.where(Filter.or(
Filter("age", isGreaterThan: 18),
Filter("verified", isEqualTo: true),
));
💡 Combining AND & OR:
You can nest Filter.and()
and Filter.or()
for advanced queries without writing inefficient workarounds.
query.where(Filter.and(
Filter("country", isEqualTo: "USA"),
Filter.or(
Filter("premiumUser", isEqualTo: true),
Filter("subscription", isGreaterThanOrEqualTo: 1),
),
));
✨ Why use this?
✅ Cleaner, more readable queries
✅ No more chaining .where()
for complex filters
✅ Firestore handles everything under the hood efficiently
This makes querying Firestore data in Flutter much more flexible! 🚀
If you're still using old .where()
chains, it's time to upgrade.
Who's already using Filter.and()
& Filter.or()
