Methods

as<T>({String? format}) → Stream<T>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

Returns a stream where each snapshot is converted to an object of type T.

asList<T>({String? format}) → Stream<List<T>?>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

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>?>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

Returns a stream where each snapshot is converted to a nullable map with values of type T.

asNonNullableList<T>({String? format}) → Stream<List<T>>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

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>>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

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>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

Updates the content at path for each snapshot in this stream asynchronously with the values from childStream

child(String path) → Stream<Snapshot>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

Takes the (grand)child defined by path of each Snapshot in this stream.

mapChildren(dynamic mapper(String key, Snapshot value)) → Stream<Snapshot>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

Updates the content of each child with the value returned by mapper

mapPath(String path, dynamic mapper(Snapshot value)) → Stream<Snapshot>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

recycle() → Stream<Snapshot>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

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>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

Updates the content at path for each snapshot in this stream.

switchChildren(Stream mapper(String key, Snapshot value)) → Stream<Snapshot>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

Updates the content of each child with the values of the stream returned by mapper

switchPath(String path, Stream mapper(Snapshot snapshot)) → Stream<Snapshot>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

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>

Available on Stream<Snapshot>, provided by the SnapshotStreamX extension

Returns a snapshot stream where each snapshot has the decoder decoder.
