Thin, but strongly typed wrapper library for cloud_firestore.

Stove 🔥🍳

Stove is the thin, but strongly typed wrapper library for cloud_firestore.

Now you can,

• take advantages of the type checker of Dart language
• avoid runtime errors due to dynamic arguments of cloud_firestore
• avoid typos due to using raw String literals for the name of document's fields

Stove provides you a happy yummy Firestore life for you! 🔥🍳

Using

Define the document class

/// User document
class User {}

That's it!

Also, you can add fields for this class if you want.

Define fields of the document

// The document `User` has fields named `name` and `gender`.
class UserField<FT, LT> implements Field<User, FT, LT> {
  final String name;
  final Converter<FT, LT> storeToLocal;
  final Converter<LT, FT> localToStore;

  const UserField._(this.name, this.storeToLocal, this.localToStore);

  static const name$ = UserField<String, String>._("name", identity, identity);
  static final gender = UserField._(
        "gender",
            (f) => Gender.values.where((g) => g.toString().contains(f)).first,
            (l) => l.toString().split(".")[1]);
}

The class represents the field of the document should extend Field<T, FT, LT>. T should be unique by each document. FT means "Type in Firesore". LT means "Type in the local environment".

You can define your own converters that converts FT and LT. You can use all type of instance if you write converters. If you don't want to convert the value, put identity converter (it through arguments).

Define children of the document

// The document `User` has a child (sub collection) named `friends`.
class UserChildren<C> implements SubCollection<User, C> {
  final String name;

  const UserChildren._(this.name);

  static const friends = UserChildren<Friend>._("friends");
}

The class represents the child (sub collection) should extend SubCollection<C>. C is the class represents the document of the element of that collection.

Using document reference

// Create the reference of new document
final userReference = Stove.instance.collection<User>("/users").document();

// Save data
await userReference.setData(DocumentDifference()
  ..set(UserFields.name$, "Bob")
  ..set(UserFields.gender, Gender.male)
);

// Update data
await userReference.updateData(DocumentDifference()
  ..set(UserFields.name$, "John")
  ..delete(UserFields.gender)
);
// Delete data

await userReference.delete();

// Get the snapshot
final userSnapshot = await userReference.get();
final name = userSnapshot.data.get(UserFields.name$);    // name: String
final gender = userSnapshot.data.get(UserFields.gender); // gender: Gender (automatically converted!)
switch (gender) {
  case Gender.male:
    ......
}

// Access sub collection
final friendsReference = userReference.SubCollection(UserChildren.friends);

Using sub collection reference

final usersReference = Stove.instance.collection<User>("/users");

// Get all documents
final snapshots = usersReference.documents();

// Listen all documents
usersReference.snapshots()
  .listen((/*List<DocumentSnapshot<User>>*/ snapshots) {
    doYourStuff(snapshots)
});

// Query documents
usersReference
  .where(UserFields.gender, isEqualTo: Gender.female)
  .order(UserFields.name$)
  .documents();
