Methods

as<T>({String? format}) Stream<T>
Returns a stream where each snapshot is converted to an object of type T.
asList<T>({String? format}) Stream<List<T>?>
Returns a stream where each snapshot is converted to a nullable list of objects of type T.
asMap<T>({String? format}) Stream<Map<String, T>?>
Returns a stream where each snapshot is converted to a nullable map with values of type T.
asNonNullableList<T>({String? format}) Stream<List<T>>
Returns a stream where each snapshot is converted to a non-nullable list of objects of type T.
asNonNullableMap<T>({String? format}) Stream<Map<String, T>>
Returns a stream where each snapshot is converted to a non-nullable map with values of type T.
asyncSetPath(String path, Stream childStream) Stream<Snapshot>
Updates the content at path for each snapshot in this stream asynchronously with the values from childStream
child(String path) Stream<Snapshot>
Takes the (grand)child defined by path of each Snapshot in this stream.
mapChildren(dynamic mapper(String key, Snapshot value)) Stream<Snapshot>
Updates the content of each child with the value returned by mapper
mapPath(String path, dynamic mapper(Snapshot value)) Stream<Snapshot>
recycle() Stream<Snapshot>
Returns a snapshot stream where each new emitted snapshot reuses the cache of the previous snapshot with the same decoder.
setPath(String path, dynamic value) Stream<Snapshot>
Updates the content at path for each snapshot in this stream.
switchChildren(Stream mapper(String key, Snapshot value)) Stream<Snapshot>
Updates the content of each child with the values of the stream returned by mapper
switchPath(String path, Stream mapper(Snapshot snapshot)) Stream<Snapshot>
Updates the content at path for each snapshot in this stream asynchronously with the values from the stream returned by the mapper callback.
withDecoder(SnapshotDecoder decoder) Stream<Snapshot>
Returns a snapshot stream where each snapshot has the decoder decoder.
