sizeHint method

  1. @override
int sizeHint(
  1. ChainType value
)
override

If possible give a hint of expected size of the encoding.

This method is used inside default implementation of encode to avoid re-allocations.

Implementation

@override
int sizeHint(ChainType value) {
  switch (value.runtimeType) {
    case Development:
    case Local:
    case Live:
      return 1;
    case Custom:
      return (value as Custom)._sizeHint();
    default:
      throw Exception(
          'ChainType: Unsupported "$value" of type "${value.runtimeType}"');
  }
}
