SnapshotDecoder.from constructor Null safety

SnapshotDecoder.from(
  1. SnapshotDecoder other
)

Create a new, unsealed SnapshotDecoder containing the converters in the decoder other.

Additional converters can be registered with SnapshotDecoder.register and SnapshotDecoder.registerWithFormat. Before being able to use this SnapshotDecoder, you'll need to seal it by calling SnapshotDecoder.seal.

Implementation

SnapshotDecoder.from(SnapshotDecoder other) {
  other._converters.forEach((key, value) {
    var l = _converters.putIfAbsent(key, () => []);
    for (var c in value) {
      l.add(c);
    }
  });
}
